|    Measuring the data locality of parallel     |
|    17 Apr 10 12:19:58    |
      From: SidTouati@inria.fr              Dear all,       does anybody knows some tools to measure the data locality of parallel       OPEN-MP applications ? (shared memory)              The PIN tool (used with MICA from Ghent) is perfect for doing this for       sequential applications. But it is not thread safe.              We modified the MICA pin tool to become thread safe, we added a lock       before and after each memory reference, but this produces an equivalent       sequential execution: the parallelism is disturbed by such excessive       locks. So the parallel behaviour is not correctly observed.              We are looking for tools allowing to measure the data locality of OPENMP       application in a thread safe way. The measurment should not "disturb"       the parallel execution too much.              Any help is appreciated.              All the best       S              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
