Here's a quick reference to several of the performance-related tools and packages that are in use on the NCSA IA-32 and IA-64 GNU/Linux clusters and SGI Altix, and pointers to where you can find them (and more information about using them) out on the 'Net.
Software is listed in alphabetical order within each section, and should not be considered an endorsement or recommendation of any software listed on this page.
Each package has a pointer to its main web page and (where available) NCSA-specific information about the package as well as information about the software's license terms.
At NCSA, VProf has been modified to accept the environment variable
VMON_FREQ to set the threshold (default 100000) for
sampling when PAPI is used.
Additionally, modifications have been made to allow the use of
all PAPI standard events (the VProf 0.12 distribution doesn't declare
them all) and to support processor native events if using PAPI 3.
A patch (unsupported) to apply these modifications is
available here. This patch has been
updated for use with either PAPI version 2 or 3.
To apply this patch, unpack the standard VProf 0.12 distribution, change into the directory containing the source code (vprof-0.12), and execute the command:
patch -p1 < PATCHFILE
where PATCHFILE corresponds to the location of the file containing the patch. Then follow the instructions in the README.NCSA file and the README file.
