- Intel Threading Tools and OpenMP
- Explicit threading methods, such as Windows threads or POSIX threads, use library calls to create, manage, and synchronize threads. Use of explicit threads requires an almost complete restructuring of affected code. On the other hand, OpenMP is a set of pragmas, API functions, and environment variables that enable one to...

- An Implementation of the POMP Performance Monitoring Interface for OpenMP Based on Dynamic Probes
- OpenMP has emerged as the standard for shared memory parallel programming. Unfortunately, it does not provide a standardized performance monitoring interface, such that users and tools builders could write portable libraries for performance measurement of OpenMP programs. This paper presents an implementation of a performance monitoring interface for OpenMP, based...

- Analyzing Overheads and Scalability Characteristics of OpenMP Applications
- Analyzing the scalability behavior and the overheads of Open-MP applications is an important step in the development process of scientific software. Unfortunately, few tools are available that allow an exact quantification of OpenMP related overheads and scalability characteristics. This paper presents a methodology which defines four overhead categories that can...

- OpenMP and Automatic Parallelization in GCC
- This paper describes the design and implementation of the OpenMP specification v2.5 in GCC. The implementation supports all the languages specified in the standard (C, C++ and Fortran), and it is generally available on any platform that supports POSIX threads. Emphasis is placed on the internal architecture and, in particular,...

- Cluster Interconnect Analysis and Comparison White Paper
- TruCluster Server Version 5.1A and higher supports Memory Channel or local area network LAN as the cluster interconnect. A cluster must have a dedicated cluster interconnect to which all cluster members are connected. This interconnect serves as a private communication channel between cluster members. This white paper provides guidelines to...

- How to demote a cluster
- I have a 2003 enterprise server. I configured it into a cluster. However, this is one machine and after making it a cluster server, I realized you need other servers with same OS to join a cluster. I want to now UNCLUSTERIZE this. How do I do that? There is...

- Exchange Cluster Checks With ClusPrep and ClusDiag (Part 2)
- Microsoft has a tool available to verify a cluster by running performance tests against cluster, as well as providing a graphical view of various components such as the network and disk layouts. In addition, this tool helps with the cluster troubleshooting process as it can examine the cluster log files....

- Cluster Computing: A Review of Cluster Characteristics across Several Leading Vendors
- The cluster systems covered differ in style and architecture from the basic systems which comprise the nodes of the cluster as well as the manner in which the nodes participate in the cluster system as a whole. Cluster operation is fundamental to VMS, unlike most systems which consist of a...

- Intel Ct leaps ahead in multi-threaded development
- At Intel research day last week, one of the most impressive things I've seen to date in the parallel programming arena leapt out on center stage. I blogged earlier this month about "The death of single-threaded development" due to the systemic shift microprocessor progression. The OpenMP code took 172 lines...

- High Availability Cluster Multiprocessing Best Practices
- The IBM High Availability Cluster Multiprocessing HACMPTM product supports a wide variety of configurations, and provides the cluster administrator with a great deal of flexibility. With this flexibility comes the responsibility to make wise choices: there are many cluster configurations that are workable in the sense that the cluster will...

- Load Balancing and OpenMP Implementation of Nested Parallelism
- Many problems have multiple layers of parallelism. The outer-level may consist of few and coarse-grained tasks. Next, each of these tasks may also be rich in parallelism, and be split into a number of fine-grained tasks, which again may consist of even finer subtasks, and so on. Here this paper...

- Installing and Configuring Sun Cluster 3.1 09/04 Software for High-Availability Applications
- The goal of the cluster is to maintain near 100 percent uptime while ensuring data integrity. More than one highly available application can be run on a cluster at a time, either sharing resources with other applications, or running on separate nodes with their own resources. The Sun Cluster environment...

- Introduction to Linux Cluster Filesystems
- Traditionally, a cluster is simply a group of servers, either PCs or workstations, acting as a single system. That definition is stretching considerably, however; cluster technology is now a dynamic field with diverse applications that is continually absorbing new features. Furthermore, cluster filesystem technologies, whether open source or proprietary, are...

- Using Microsoft iSCSI Software Target to Provide Shared-Disk Resources to Clusters
- Software clustering is the configuration of two or more servers to work as a unit. When one server fails, another node in the cluster picks up the workload, and the cluster continues to function without interruptions. The Microsoft iSCSI Software Target enables the HP All-in-One Storage System or ProLiant Storage...
