As a general practice when debugging parallel programs, debug runs of your program with the fewest number of processes possible (2, if you can). To use valgrind, run a command like the following: mpirun -np 2 --hostfile hostfile valgrind ./mpiprog. This example will spawn two MPI processes, running mpiprog in valgrind.Employee reviews are an important part of any business.
