The MPI Performance Snapshot (MPS) is a scalable lightweight performance tool for MPI applications. It collects a variety of MPI application statistics (such as communication, activity, and load balance) and presents it in an easy-to-read format. The tool is not available separately but is provided as part of the Intel® Trace Analyzer and Collector installation. This article will serve as a quick getting started guide.
The Intel® Parallel Studio XE 2015 Update 3 Cluster Edition for Linux* and Windows* combines all Intel® Parallel Studio XE and Intel® Cluster Tools into a single package. This multi-component software toolkit contains the core libraries and tools to efficiently develop, optimize, run, and distribute parallel applications for clusters with Intel processors. This package is for cluster users who develop on and build for IA-32 and Intel® 64 architectures on Linux* and Windows*, as well as customers running over the Intel® Xeon Phi™ coprocessor on Linux*. It contains:
The Intel® Trace Analyzer and Collector employs the use of the Structured Trace File Format (STF) in order to profile MPI applications in a scalable and efficient manner.
I have established secure shell (SSH) connectivity on my cluster where each node has a public key. However, when I use any secure shell utility on the cluster, I am still prompted for a password. What am I doing wrong?
This Beta release of the Intel® Parallel Studio XE 2016 introduces a major change to the 'Named-user' licensing scheme (provided as default for the 2016 Beta licenses). Read below for more details on this new functionality as well as a list of special exceptions. Following a thorough Beta testing period, implementation will carry forward into the product release.
The What's New pages describe features and changes since the last release.
The Release Notes include important information, such as:
On Linux* OS: After unpacking the Intel® Trace Collector archive in a folder of your choice read the file relnotes.txt for information on how to install Intel® Trace Collector.
On Microsoft Windows* OS: run the installation file setup.exe and follow the instructions given in the installation wizard.
Traces of just one process can be generated with the libVTcs library, which allows the generation of executables that work without MPI.
Linking is accomplished by adding libVTcs.a (VTcs.lib on Microsoft* Windows* OS) and the libraries it needs to the link line:
For interactive debugging the application has to be started so that stderr is printed to a console window. Then one can follow which errors are found while the application is running and start analyzing them without having to wait for it to complete. If critical errors are found early on one could even abort the run, fix the problem and restart. This ensures a much faster code and test cycle than a post-mortem analysis.
