Cachetest

Author: Alex Szlavik Email: [email protected]

INTRODUCTION: Cachetest is a small POSIX compliant appliation allowing for the characterization and study of contemporary memory hierarchies.

COMPILING: The cachtest suite utilizes the gnu autoconf process for generating makefiles and determining system header file compatibility.

If you wish to use Cachetest with PAPI support, use --with-papi= If PAPI is globally installed and visible via your PATH settings, you do not need this option. Alternatively, Cachetest ships with a custom PMU event interface, which is used if no PAPI installation is found.

./configure make (optionally) make install

RUNNING: Cachetest can be run directly via the binary which was installed, or via the testing scripts found in scripts/ .

cachetest's Issues

one of the

commenting out this part causes the compilation on Power7 to throw 'undefined reference to vtable for Perf_Cachetest'. Which is caused due to having the prototype in Perf_Cachetest.hpp but not including the implementation in the cc file. I guess either remove both or include both !

You commented that out to prevent breaking PAPI in this commit:

automake version mismatch

I am using automake 1.11 and although configure was running without problems, make was complaining about autmake-1.13 command not found. I had to do

autoreconf --force --install

for make to run successfully.
