Hello to all and to whoever is from the United States, Happy 4th of Jully !


I am having these collective aborts while executing a program. More specifically the error is :
rank 7 in job 38  Calliope_50667   caused collective abort of all ranks   exit status of rank 7: killed by signal 11  [cli_2]: aborting job: Fatal error in MPI_Allgather: Error message texts are not available [cli_4]: aborting job: Fatal error in MPI_Allgather: Error message texts are not available

But the MPI_Allgather command it's written correctly, since i checked it multiple times and what about the "Error message texts are not available"?

MPI_Allgather(&docs, 1, MPI_INT, texts_vectors, 1, MPI_INT, MPI_COMM_WORLD);

Where docs is a int variable holding a single value for each node, and texts_vectors is an int array with the size of the population of the nodes.

I compile the programm using mpicc -g -o prog prog.c -lm and execute using mpiexec -n number_of_nodes `pwd`/prog
I am using MPICH2 1.0.6 in a linux cluster machine that i use for the purposes of my bachelor thesis. I know it's an older version, but the machine belongs to an institute, so i don't have the permission to upgrade it.
