Hi all,

I tried to compile Pelegant from source code on Ubuntu 13.04 64-bit. After successful compilation I tried to run the application and got the following error:

Code: Select all

Fatal error in PMPI_Bcast: Invalid root, error stack:
PMPI_Bcast(1478): MPI_Bcast(buf=0x8b63e8, count=1, MPI_LONG, root=1, MPI_COMM_WORLD) failed
PMPI_Bcast(1440): Invalid root (value given was 1)

Could anyone help me fixing this problem?

Thanks a lot and regards,
Manuel

Sorry it has taken be so long to respond. The forum notification system didn't work for your message and I was only recently informed about it.

After a google search, it appears that you compiled with one version of mpi and are using a different version to launch the program. We offer two different pre-compiled versions of Pelegant on Ubuntu 13.04 64bit using the standard packages for openmpi and mpich2 that are distributed with Ubuntu. You can also compile your own using the Build-AOP-RPMs script and telling it where your version is located. When you go to launch Pelegant with mpiexec or mpirun, you need to use the same version that Pelegant was built with.
