Re^8: Limit on number of cores

Hi,

it looks like you are using nt-mpich-smp MPI implementation.
The problem you faced is related to this MPI, not to Firefly.
As I mentioned previously, you need to increase the size of
the shared memory segment, e.g. add the following line to the
batch file you are using to start Firefly:

set MPI_GLOBMEMSIZE=536870912

Kind regards,
Alex Granovsky
