Ganglia

Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and grids. It is based on a hierarchical design targeted at federations of clusters. Ganglia is currently in use on over 500 clusters around the world and has scaled to handle clusters with 2000 nodes.

RiDE Computing

RIDE is a multi-flow HPC paradigm and the system that implements it. It aims to beat MPI and OpenMP for simplicity of use. It also beats approaches such as MapReduce and Task Flow because RIDE solves wider range of tasks.

likwid

Likwid stands for Like I knew what I am doing. This project contributes easy to use command line tools for Linux to support programmers in developing high performance multi threaded programs. It contains the following tools: likwid-topology: Show the thread and cache topology likwid-perfCtr: ... [More] Measure hardware performance counters on Intel and AMD processors likwid-features: Show and Toggle hardware prefetch control bits on Intel Core 2 processors likwid-pin: Pin your threaded application without touching your code (supports pthreads, Intel OpenMP and gcc OpenMP) There are already a bunch of performance counter tools available. Likwid stands out because: No kernel patching, any vanilla kernel with the standard msr module works Transparent, always clear which events are chosen, event tags have the same naming as in documentation Ease of use, no java hog, simple to build, no need to touch your code, configurable from outside. Clear CLI interface Multiplatform, likwid supports Intel and AMD processors Up to date, likwid tries to fully support new processors as soon as possible If you encounter problems feel free to ask questions in the User Mailing List. NOTICE Although Likwid is already fully usable Likwid is not yet released. I need your help to find bugs and improve Likwid to ensure a high quality for the release. Give it a try and test it. If you encounter problems write a email to me or the Forum. I promise a quick reaction time to fix errors or respond to feature requests. [Less]

OLib

High performance library of mathematical functions and algorithms

io-watchdog

io-watchdog is a facility for monitoring user applications and parallel jobs for "hangs" which typically have a side effect of ceasing all IO in a cyclic application (i.e. one that writes something to a log or data file during each cycle of computation). The io-watchdog attempts to watch ... [More] all IO coming from an application and triggers a set of user-defined actions when IO has stopped for a configurable timeout period. Read the full IO Watchdog README NEWSio-watchdog v0.7 released2009-11-17 The major feature in this new version of io-watchdog is the addition of a client API to get and set the current watchdog timeout. See the io-watchdog(3) manpage for more information about using the libio-watchdog library. Other changes in this release include Add -q, --quiet option to io-watchdog Set IO_WATCHDOG_TIMEOUT and IO_WATCHDOG_TARGET in the environment of action scripts. Fix for hangs in io-watchdog on exec(2) failures The io-watchdog now exits by default after the first timeout event is reached. This means that if the monitored process is not terminated by any action script, then it will continue to run unmonitored by the watchdog. There is a new option to io-watchdog(1), --persistent which restores the old behavior. The spec file included with the distribution now splits the io-watchdog RPM into a main package and -libs, -devel, and -slurm subpackages. A small testsuite is now included with the io-watchdog source. [Less]
