Dear all, Glad to meet you in the ompi society.
I have a small question when using openmpi to compile petsc which is scientific computing tools. I'm using openmpi-2.0.1 with slurm in the cluster. After compiling petsc, I run the following test to check the multi-processors ability: srun -n 8 --ntasks-per-node 24 -N 1 -c 1 make PETSC_DIR=/rigel/free/users/rs3741/SourceCode/petsc-3.5.4 PETSC_ARCH=gnu-opt streams NPMAX=8 It always generate the following error: Number of MPI processes 8 > > Process 0 node013 > > Process 1 node013 > > Process 2 node013 > > Process 3 node013 > > Process 4 node013 > > Process 5 node013 > > Process 6 node013 > > Process 7 node013 > > Function Rate (MB/s) > > Copy: 12262.7658 > > Scale: 19360.2183 > > Add: 17548.6988 > > Triad: 34414.3445 > > Function Rate (MB/s) > > Copy: 61824.9894 > > Scale: 57833.3291 > > Add: 66578.3984 > > Triad: 54500.8303 > > Function Rate (MB/s) > > Copy: 6266.7602 > > Scale: 6841.4854 > > Add: 9856.5828 > > Triad: 10460.4597 > > ------------------------------------------------ > > Traceback (most recent call last): > > File "process.py", line 110, in <module> > > process(len(sys.argv)-1) > > File "process.py", line 26, in process > > triads[size] = float(fields[size+5].split()[1]) > > IndexError: list index out of range > > gmake[1]: [stream] Error 1 (ignored) > > Traceback (most recent call last): > > File "process.py", line 110, in <module> > > process(len(sys.argv)-1) > > File "process.py", line 26, in process > > triads[size] = float(fields[size+5].split()[1]) > > IndexError: list index out of range > > gmake[1]: [streams] Error 1 (ignored) > > > Do you have any ideas on this issue? Any help will be appreciated. Best regard.
