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?
Thanks
Raj
