Can you send the optupt from the following runs. You can do this with src/ksp/ksp/examples/tutorials/ex2.c - to keep things simple.
petscmpirun -n 2 taskset -c 0,2 ./ex2 -log_summary | egrep \(MPI_Send\|MPI_Barrier\) petscmpirun -n 2 taskset -c 0,4 ./ex2 -log_summary | egrep \(MPI_Send\|MPI_Barrier\) petscmpirun -n 2 taskset -c 0,6 ./ex2 -log_summary | egrep \(MPI_Send\|MPI_Barrier\) petscmpirun -n 2 taskset -c 0,8 ./ex2 -log_summary | egrep \(MPI_Send\|MPI_Barrier\) petscmpirun -n 2 taskset -c 0,12 ./ex2 -log_summary | egrep \(MPI_Send\|MPI_Barrier\) petscmpirun -n 2 taskset -c 0,14 ./ex2 -log_summary | egrep \(MPI_Send\|MPI_Barrier\) Satish
