Yes, I believe you could. I used to run my parallel MPI program on one CPU environment. It was fine. It depends on the way you configure your program. The only thing is that you won't get real performance due to pseudo-parallelism. So, it may not be useful to you in that sense. But you can run the same program later, without any modification, once you manage to get real parallel network. -sk ---------------------------------------- Perpetual optimism is a force multiplier
