   Measuring the data locality of parallel    
   17 Apr 10 12:19:58

   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
