Computational methods for fracture 1_2
Timon RABCZUK: A state-of-the-art overview on computational methods for fracture will be presented. The lecture will discuss especially methods for discrete cracks, i.e. extended meshfree and finite element methods, the phantom node method (a special case of the extended finite element method), extended IGA (Isogeometric analysis) formulations, efficient remeshing techniques and peridynamics (PD). The focus will be on ‘enriched’ methods based on local partition of unity. As an alternative to discrete crack methods, the phase field approach to fracture will be presented which shows similarities to nonlocal or gradient models. The lecture starts with an introduction to meshfree methods (MMs) and different ways to model fracture in MMs. In this context, the concept of intrinsic and extrinsic enrichment schemes based on a local partition of unity will be explained. Subsequently, the extended finite element method (XFEM) for fracture in continua and structures will be addressed. Different enrichment schemes for brittle and ductile failure will be shown. Solutions to difficulties due to blending, enrichment and integration will be given. As tracking the crack path is of major concern in computational methods that preserve crack path continuity, different crack tracking techniques will be discussed. Alternatives to XFEM, in particular extended meshfree methods, the cracking particles methods, the phantom node method and extended IGA formulations will be presented exploiting for example the higher order continuity of meshfree and IGA approximations. One part of the lecture will be dedicated to efficient remeshing techniques that do not require adding degrees of freedom. Subsequently, an overview of peridynamics (PD) will be given which is particularly suitable to model dynamic fracture with numerous cracks and complex fracture patterns. The focus will be on bond-based (BB) and ordinary state based peridynamics. A novel variable horizon peridynamics formulation for adaptive simulation with error control will be presented as well. Finally, the phase field approach including advantages, drawbacks and limitations will be explained as an alternative to discrete crack methods. The lecture will close with a brief overview on cracking criteria for non-linear fracture.

Verification v/s Validation ||| Static Testing v/s Dynamic Testing
Verification is intended to check that a product, service, or system (or portion thereof, or set thereof) meets a set of design specifications.[3][4] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service or system, then performing a review or analysis of the modeling results. In the post-development phase, verification procedures involve regularly repeating tests devised specifically to ensure that the product, service, or system continues to meet the initial design requirements, specifications, and regulations as time progresses.[4][5] It is a process that is used to evaluate whether a product, service, or system complies with regulations, specifications, or conditions imposed at the start of a development phase. Verification can be in development, scale-up, or production. This is often an internal process. Validation is intended to ensure a product, service, or system (or portion thereof, or set thereof) results in a product, service, or system (or portion thereof, or set thereof) that meets the operational needs of the user.[4][6] For a new development flow or verification flow, validation procedures may involve modeling either flow and using simulations to predict faults or gaps that might lead to invalid or incomplete verification or development of a product, service, or system (or portion thereof, or set thereof). A set of validation requirements (as defined by the user), specifications, and regulations may then be used as a basis for qualifying a development flow or verification flow for a product, service, or system (or portion thereof, or set thereof). Additional validation procedures also include those that are designed specifically to ensure that modifications made to an existing qualified development flow or verification flow will have the effect of producing a product, service, or system (or portion thereof, or set thereof) that meets the initial design requirements, specifications, and regulations; these validations help to keep the flow qualified.[citation needed] It is a process of establishing evidence that provides a high degree of assurance that a product, service, or system accomplishes its intended requirements. This often involves acceptance of fitness for purpose with end users and other product stakeholders. This is often an external process. It is sometimes said that validation can be expressed by the query "Are you building the right thing?"[7] and verification by "Are you building it right?".[7] "Building the right thing" refers back to the user's needs, while "building it right" checks that the specifications are correctly implemented by the system. In some contexts, it is required to have written requirements for both as well as formal procedures or protocols for determining compliance. It is entirely possible that a product passes when verified but fails when validated. This can happen when, say, a product is built as per the specifications but the specifications themselves fail to address the user's needs.

The talk will touch on three protocols from this family and relate them to each other: The first, Rumor Mongering, spreads gossip in each call. This protocol was invented at Xerox PARC for the purpose of synchronizing replicas in the Clearinghouse directory service. The second, Name Dropper, pushes new neighbors in each call. This protocol was developed at Akamai for network discovery in a partially connected network. The third, SWIM, pulls a heartbeat in each call. This mechanism was developed at Cornell University in order to implement scalable failure detection.

Drift-insensitive distributed calibration of probe microscope scanner: Approach description
Elsevier's Audio Slides http://audioslides.elsevier.com//ViewerSmall.aspx?source=1&doi=10.1016/j.apsusc.2015.10.108 A short introduction to the research article: R. V. Lapshin, Drift-insensitive distributed calibration of probe microscope scanner in nanometer range: Approach description, Applied Surface Science, vol. 359, pp. 629-636, 2015 (DOI: 10.1016/j.apsusc.2015.10.108). The article is available for free at the following link: http://www.niifp.ru/staff/lapshin/en/index.htm#approach2015 Slide 1. Title Dear Colleagues! My name is Rostislav Lapshin, I am a research scientist from the Institute of Physical Problems, Zelenograd, Moscow, Russian Federation. I am going to briefly report about a new method, which is presented in my recent paper “Drift-insensitive distributed calibration of probe microscope scanner in nanometer range: Approach description” published in Applied Surface Science journal, in October 2015. Slide 2. Main concept The method of distributed calibration of a probe microscope scanner consists in a search for a net of local calibration coefficients in the process of automatic measurement of a standard surface, whereby each point of the movement space of the scanner can be defined by a unique set of scale factors Slide 3. Applied methods To eliminate the negative influence of noise, thermal drift and creep upon the distributed calibration results, the following methods were used: 1. Feature-oriented scanning. 2. Feature-oriented positioning. 3. Counter-scanned images. Slide 4. Partitioning the scanner movement space with a net At the beginning of the distributed calibration, the scanning space is partitioned with a square cell net where the nodes correspond to the absolute integer coordinates x, y, z of the scanner. During the calibration, three local calibration coefficients corresponding to axes X, Y, Z of the scanner are determined in the neighborhood of each net node. Slide 5. Simplified flowchart of the distributed calibration The procedure of distributed calibration is a sequence of three basic measurement operations: probe attachment (position 2), aperture scanning (position 3), and skipping (position 4), which are carried out in each net node of the scanner’s movement space. Slide 6. Local calibration structure ABC of a standard surface The attachment of the microscope probe to a surface feature allows capturing the feature located near the current net node and holding it within the “field of view” of the instrument. Scanning a small neighborhood called an aperture around the captured feature followed by recognition of topography in the obtained scan enables detecting the local calibration structure. Local calibration structure usually consists of three features A, B and C such that the distances between them are a priori known precisely. Atoms and/or interstices of the crystal lattice are used as features. To get the sought-for local calibration coefficients, the distances between the features A and B, A and C should be measured. Drift-insensitive measurement of these distances is carried out within the skipping operation. Slide 7. Application fields The developed calibration approach can be used in the following fields: 1. Accurate calibration of a probe microscope scanner in nanometer and subnanometer ranges. 2. Automatic characterization of lattice crystal parameters and surface defects. 3. Analysis and certification of SPM operation: measurements of thermal drifts, creeps, nonlinearities, nonorthogonalities, and spurious couplings. Slide 8. Conclusions 1. A method of automatic distributed calibration has been suggested that allows excluding errors caused by static nonlinearities, nonorthogonalities and spurious couplings of a probe microscope piezoscanner. 2. The calibration database obtained during calibration is insensitive to microscope head thermal drift and piezoscanner creep because of the application of the feature-oriented scanning methodology. 3. The lattice constant of a crystal has been used as a nature length standard of nanometer range. Finishing, I wish you all good luck in your research!

There is No Such Thing as User Error
User Centric is now a part of GfK! Read about our Medical Device UX research and design solutions (http://www.gfk.com/solutions/ux/health/Pages/Medical-device-UX-research-and-design.aspx). Medical device design necessitates an assessment of risk. The need is prudent given their ecosystem of use, but also mandated by regulatory agencies. Risk management uses analysis protocols to identify and predict situations where a device may fail and assess the consequences. Common techniques, like Failure Mode and Effects Analysis (FMEA) must expand to go beyond engineering and material failure to identify hazard risks due to user-device interactions or "use errors." During this webinar, we will discuss the practice of the FMEA with added upgrades, such as a Task Analysis and how integration with simulated use labs can help you and your design team be more successful at reducing patient risk.

How to Detect Soft Corruption in Oracle 12c Database
Detection of Soft Corruption in 12c: To use the scripts below replace : , ",# and $ by proper bracket Lets Create a tablespace and small table. SQL: create tablespace DEMO1 datafile '/u02/tstdb1/TSTDB1/datafile/demo01.dbf' size 50M SQL: create table objects tablespace DEMO1 as select * from dba_objects; SQL: alter table objects add constraint pk_obj primary key #object_id$; SQL: create index idx_obj_name on objects#object_name$ tablespace demo1; Backup tablespace. RMAN: backup tablespace DEMO1; We need to put the DB in archivelog first Rebuild index with NOLOGGING option to simulate soft corruption later. RMAN: alter index idx_obj_name rebuild nologging; Confirm that we have datafiles that require backup because they have been affected with NOLOGGING operation. RMAN: report unrecoverable; Simulate corruption. RMAN: alter database datafile 5 offline; RMAN: restore datafile 5; RMAN: recover datafile 5; RMAN: alter database datafile 5 online; Query table with corrupted index and notice error. SQL: select count#*$ from objects where object_name like 'A%'; Let’s perform validation of datafile to check block corruption. RMAN: backup validate check logical datafile 5; Notice that we have 457 blocks marked corrupt but v$database_block_corruption view is empty. SQL: select count#*$ from v$database_block_corruption; Let’s query v$nonlogged_block view. set lines 200 set pages 999 select file#, block#, blocks,object#,reason from v$nonlogged_block; Will RMAN detect that we have corrupted blocks? RMAN: backup datafile 5; RMAN backup won’t fail due to NOLOGGING corrupt blocks and our backup will contain soft corrupted blocks. Let’s Identify corrupt segments using v$nonlogged_block view. set lines 2000 set pages 9999 col owner for a20 col partition_name for a10 col segment_name for a20 SELECT e.owner, e.segment_type, e.segment_name, e.partition_name, c.file# , greatest#e.block_id, c.block#$ corr_start_block# , least#e.block_id+e.blocks-1, c.block#+c.blocks-1$ corr_end_block# , least#e.block_id+e.blocks-1, c.block#+c.blocks-1$ - greatest#e.block_id, c.block#$ + 1 blocks_corrupted FROM dba_extents e, V$NONLOGGED_BLOCK c WHERE e.file_id = c.file# AND e.block_id "= c.block# + c.blocks - 1 AND e.block_id + e.blocks - 1 := c.block# UNION SELECT s.owner, s.segment_type, s.segment_name, s.partition_name, c.file# , header_block corr_start_block# , header_block corr_end_block# , 1 blocks_corrupted FROM dba_segments s, V$NONLOGGED_BLOCK c WHERE s.header_file = c.file# AND s.header_block between c.block# and c.block# + c.blocks - 1 UNION SELECT null owner, null segment_type, null segment_name, null partition_name, c.file# , greatest#f.block_id, c.block#$ corr_start_block# , least#f.block_id+f.blocks-1, c.block#+c.blocks-1$ corr_end_block# , least#f.block_id+f.blocks-1, c.block#+c.blocks-1$ - greatest#f.block_id, c.block#$ + 1 blocks_corrupted FROM dba_free_space f, V$NONLOGGED_BLOCK c WHERE f.file_id = c.file# AND f.block_id "= c.block# + c.blocks - 1 AND f.block_id + f.blocks - 1 := c.block# order by file#, corr_start_block# / This is the best outcome to get if you notice corruption errors. All errors are related to index corruption so we could fix this problem rebuilding index. alter index idx_obj_name rebuild; Simply issuing "alter index rebuild" command won't work. We should mark index unusable to drop segment before rebuilding it or just rebuild index with online option. It is better choice to mark index unusable because you don't need additional space then, but I will simply rebuild index with online option and see what will happen. SQL: alter index idx_obj_name rebuild online; Index altered. SQL: select count#*$ from objects where object_name like 'A%'; No errors... but, let's validate datafile for corruption. RMAN: backup validate check logical datafile 5; Notice "Marked Corrupt" column. Hm... 457 like before. Don't worry, this is not new corruption. These are FREE blocks which will be reused and Oracle will automatically re-format those blocks. Query the v$nonlogged_block view again as given above. We could force re-formatting creating dummy table and inserting data to dummy table. Check Doc ID 336133.1. create table s # n number, c varchar2#4000$ $ nologging tablespace DEMO1; SQL: BEGIN FOR i IN 1..1000000 LOOP INSERT /*+ APPEND */ INTO sys.s select i, lpad#'REFORMAT',3092, 'R'$ from dual; commit ; END LOOP; END; / SQL: drop table sys.s purge; Notice that we don't have corrupted blocks any more. RMAN: backup validate check logical datafile 5;

Stochastic Optimization for x86 Binaries
Google Tech Talks January 12, 2015 (more info below) ABSTRACT The optimization of short sequences of loop-free fixed-point x86_64 code sequences is an important problem in high-performance computing. Unfortunately, the competing constraints of transformation correctness and performance improvement often force even special purpose compilers to produce sub-optimal code. We show that by encoding these constraints as terms in a cost function, and using a Markov Chain Monte Carlo sampler to rapidly explore the space of all possible programs, we are able to generate aggressively optimized versions of a given target program. Beginning from binaries compiled by gcc -O0, we are able to produce provably correct code sequences that either match or outperform the code produced by gcc -O3, and in some cases expert hand-written assembly. Because most high-performance applications contain floating-point computations, we extend our technique to this domain and show a novel approach to trading full floating-point precision for further increases in performance. We demonstrate the ability to generate reduced precision implementations of Intel's handwritten C numerics library that are up to six times faster than the original code, and achieve end-to-end speedups of over 30% on a direct numeric simulation and a ray tracer. Because optimizations that contain floating-point computations are not amenable to formal verification using the state of the art, we present a technique for characterizing maximum error and providing strong evidence for correctness. Publication list: http://cs.stanford.edu/people/eschkufz/ Github: https://github.com/eschkufz/stoke-release About the speaker Eric Schkufza is a postdoctoral scholar at Stanford University working with professor Alex Aiken. He graduated from Stanford University with a PhD in computer science in June 2014. He is interested in applying stochastic search techniques to the design of optimizing compilers.

MCTS 70-680: Performance Monitor and Data Collector Sets in Windows 7
This video will look at how to use the Performance Monitor and Data Collector Sets to measure performance in Windows 7. The Performance Monitor can provide charts of current real time performance. Performance monitor can't be scheduled but Performance Monitor settings can be imported into a Data Collector Set and scheduled from in there. The Data Collector Set supports any Performance Monitor counters plus additional settings and measurements from other parts of the system. Bottleneck A bottleneck in computers is described as one component which can seriously reduce the performance of the rest of the computer. A slow or over worked hard disk could cause a bottleneck. For example, if the hard disk was too slow, the CPU may spend most of its time idle because it is waiting for data from the hard disk. The most common bottle neck is RAM. When there is not enough RAM in a system, the system will starting using the hard disk as virtual RAM. This causes poor performance for the whole system. When you upgrade a bottleneck in a system, the performance of the complete system should be dramatically increased. For the exam, remember that if performance is poor for short periods of time, e.g. the CPU spikes to 100% and drops just as quick, this is not an indication of a bottleneck. Bottlenecks are when the system is slowed down by one component regularly. A small CPU spike or heavy disk activity while a program loads does not normally mean that you need to upgrade your system. Permissions There are two groups which determine what you can access in Performance Monitor and Data Collector Sets as listed below. Performance monitor group: Allows the user to see real time information in the performance monitor. Performance log users groups: Same as above but also allows the user to make changes to Data Collector Sets. Performance Monitor Performance Monitor is found in administrative tools under the start menu or control panel. In order to track different parts of the system, you need to add a counter. There are counters for every different part of the system and a lot of counters can be sub divided. For example, if you have more than one hard disk or CPU, you can select what is called an instance. For each additional piece of hardware of the same type in the system, a new instance is created which can be tracked individually. If you want to track overall performance, instead of selecting an instance, you can select the option for total. Data Collector Sets A Data Collector Set will collect data from a number of different areas of the system over a set period of time. The results from this are put into a report. A Data Collector Set can be scheduled to run at certain times and each run will be put into a report. Data Collector Sets allow you to gather information over a period of time and create a history for the computer. Using this allows you to make future decisions about whether more RAM is required in the server.

Dropped Samsung Laptop Hard Disk Corrupted
This laptop was sent over to me by a friend. They said it was dropped flat to the ground. I don't know about that nature of the drop but during boot time it said BOOTMGR is missing. I was delighted that major components was still active owing to the fact that it still boots. However the hard drive being one of the most sensitive component in the laptop did not survive. I first thought to format and reinstall however I may write over the Thesis files they want me to recover. So I finally decided to remove the hard drive and port it to a PC instead. However the Partition Tables were corrupted and it does not appear as a drive until the Partition Tables are repaired. During repair this is what I got. Unreadable sections aplenty.

Isolating Cluster Jobs for Performance and Predictability, Brooks Davis (DCBSDCon 2009)
Isolating Cluster Jobs for Performance and Predictability, Brooks Davis (DCBSDCon 2009) At The Aerospace Corporation, we run a large FreeBSD based computing cluster to support engineering applications. These applications come in all shapes, sizes, and qualities of implementation. To support them and our diverse userbase we have been searching for ways to isolate jobs from one another in ways that are more effective than Unix time sharing and more fine grained than allocating whole nodes to jobs. In this paper we discuss the problem space and our efforts so far. These efforts include implementation of partial file systems vitalization and CPU isolation using CPU sets. Source: Jason Dixon

CPU & DRAM Bugs: Attacks & Defenses
In the quest for higher performance, modern CPUs make heavy use of speculative execution. Unfortunately, speculative execution opens the possibility of side-channel attacks in which malicious parties can read the memory of co-located processes, OSes, and VMs (e.g., Meltdown, Spectre). Similarly, in the quest for higher memory capacities, modern DRAMs have drastically increased the density of memory cells on a chip. This high cell density opens the possibility of attacks that cause bit flips in DRAM (e.g., Rowhammer). A single bit flip is sufficient to lead to serious security breaches, such as privilege escalation, remote login, or factoring an RSA private key. Unfortunately, no single silver bullet for stopping these types of attacks exists. These attacks all stem from hardware “bugs.” While fixing each particular bug is feasible, the hardware life-cycle is very long, and the fixes often come with serious performance and cost overheads. Software-based fixes offer a faster response, but also may impose significant overhead. The goal of this session is to discuss the state of the art techniques in performing such attacks and defending against them using both hardware and software.
