Greetings
When running mpi code on 32 procs, with gm, lam 7.1.1 gives me the
following error:
-----------------------------------------------------------------------------
It seems that rank 13 was not able to allocate additional
DMA-accessible memory for Myrinet. DMA-accessible memory is memory
which the Myrinet cards can access. Typically, OS's have fixed limits
on how the total amount of DMA memory can be allocated at one
time. Long MPI messages require that a large amount of DMA-accessible
memory be allocated. If possible, try using smaller messages or
adjusting the OS's DMA limit. :-(
GM failed to allocate a DMA block of 16428 bytes.
-----------------------------------------------------------------------------
The same code runs without any problems on mpich 1.2.6..13b (with gm)
and also runs without any problems with lam when rpi is set to tcp. Any
ideas, suggestions?
NB This is on CCT's supercomputer: supermike, x86 arch, and everything
was compiled with intel 8.0 C/C++/F90 compilers.
