Hi all,
I tried a google/mailing list search for this but came up with nothing, so here
goes:
Is there any level of automation between open mpi's dynamic process management
and the SGE queue manager?
In particular, can I make a call to mpi_comm_spawn and have SGE dynamically
increase the number of slots?
This seems a little far fetched, but it would be really useful if this is
possible. My application is 'restricted' to coarse-grain task parallelism and
involves a work load that varies significantly during runtime (between 1 and
~100 parallel tasks). Dynamic process management would maintain an optimal
number of processors and reduce idling.
Many thanks,
This is an interesting idea but no integration has been done that would
allow an MPI job to request more slots.
