Im using AMD opteron 4-core PC. When i parallelise(Using OpenMP) and run a serial legacy application on the 4-core i get very inconsistent results when compared to the results on a single or dual core. I want to benchmark my PC to know how well the 4-cores are being utilised and to check the load on each core. I also want to know if the program is bein run on four threads as expected(i've used default settings of openmp to spawn four threads). Could someone please suggest some good tools that would give the above information as well as the information on the memory usage etc....


I've used Code analyst but the results are not clear...
It shows four threads running on a single core.. Its pretty confusing
