Answers for the questions raised during the April session of our Introduction to High Performance Application Development for Intel® Xeon® & Intel® Xeon Phi™ processors class have been assembled. There were some duplicates and other questions we couldn't decipher, either because of the wording or because of implied context that was not spelled out. We tried to address the rest, which appear below:

Using Intel® MPI Library and Intel® Xeon Phi™ coprocessor tips
1. Check prerequisites
- Each host and each Intel® Xeon Phi™ coprocessor should have a unique IP address across a cluster;
- ssh access between host(s) and Intel® Xeon Phi™ coprocessor(s) should be password-less;
- Update the Intel® Manycore Platform Software Stack (Intel® MPSS) to current version;
O que é o Intel® Xeon Phi™ e como ele atinge o impressionante processamento de 1 TFlops
Intel® Xeon Phi™ - 61 cores, 244 threads, 8 GB de memória DDR5 e 1 TFlops.
Antes de mais nada, gostaria de apresentar o Intel® Xeon Phi™ e mostrar como esta pequena obra de arte tecnológica pode lhe trazer benefícios.
Intel(R) Software Development Tools Demystified: The Packaging, Reference Guides, User Guides, BKMs, Getting Support
This article is a brief summarizing "List of Links" to find tool documentation, with a short explanation of Intel's software development tool packaging.
This graphic explains the way Intel tools are packaged; you have the option of downloading and installing individual tools, or downloading and installing the 'bundles'.
Is it time to replace the TOP 500 list?
A new TOP500 list was released at SC12. Is this one-dimensional benchmark still relevant in today's diverse HPC fields of computation?
OpenMP 4.0 may offer important solutions for targeting and vectorization
The upcoming OpenMP 4.0 will be discussed at SC12, and there will be a number of additions I'm particularly excited to see coming from OpenMP. They are: "SIMD extensions" and "targeting extensions." One helps make the intention of a developer to have code vectorized efficiently be realized, and the other allows for the first time an industry standard to designate code and data be targeted to an attached device.
Intel® Cluster Checker 2.0 - What's New?
Intel® Cluster Checker version 2.0 provides many new and improved features.
The goal of this version is to include support for third generation Intel® Core™ (codename Ivy Bridge) processors. All the packaged High Performance Computing benchmarks were rebuilt using latest releases of the Intel® Cluster Tools. The list of test modules was streamlined by merging similar checks as well.
VMware Fusion 5 supports Intel® VTune™ Amplifier event sampling
One of the great features in Intel® VTune™ Amplifier is the use of the event monitoring registers built into Intel processors. These can give us important insights into what is really happening on a system. The event monitoring allows the profiling of code in terms of what causes caches misses, unaligned memory accesses, denormalized numeric computations and hundred of other types of processor and memory activity.
Get the Most out of Intel Compilers for your Ultrabook Apps
First, let me begin by saying that compiler switches are mainly targeted for specific processors (not OS's.) With the recent launch of the 3rd Generation Intel Core Processors (code-named Ivy Bridge), developers may be looking for information on any new switches that might have been developed to specifically support (and run the best on) our latest architecture. This blog will include the following:
