Hi Josh, Thanks for the email. I have install BLCR 0.8.1 and openmpi 1.3 on my laptop with Ubuntu 8.04 on it. It works fine.
I now tried the installation on the cluster ( on one machine for now) in my university. ( the administrator installed it) i am not sure if he followed the steps i gave him. I am checkpointing a simple mpi application which looks as follows: #include <mpi.h> #include <stdio.h> int main(int argc, char **argv) { int rank,size; MPI_Init(&argc, &argv); MPI_Comm_rank(MPI_COMM_WORLD, &rank); MPI_Comm_size(MPI_COMM_WORLD, &size); printf("I am processor no %d of a total of %d procs \n", rank, size); system("sleep 30"); printf("I am processor no %d of a total of %d procs \n", rank, size); system("sleep 30"); printf("I am processor no %d of a total of %d procs \n", rank, size); system("sleep 30"); printf("bye \n"); MPI_Finalize(); return 0; } Do you think its better to re install BLCR?
