Hello,
Sometimes we have users that like to do from within a single job (think
schedule within an job scheduler allocation):
"mpiexec -n X myprog"
"mpiexec -n Y myprog2"
Does mpiexec within Open MPI keep track of the node list it is using if
it binds to a particular scheduler?
For
Hello,
I looked into this a few months back, although we have had OK
luck using LAM with R/MPI. I emailed the author of R/MPI, Dr.
Hao Yu and his answer was:

Hello Ralph,
This is great news! Thanks for doing this. I will try and get around
to it soon before the holiday break.
The allocation scheme always seems to get to me. From what you describe
that is how I would have seen it. As I've gotten to know osc mpiexec
through the years I think they li
Hi Chris
Okay, we have modified the pernode behavior as you requested (on the trunk
as of r12821)- give it a shot and see if that does it. I have not yet added
the npernode option, but hope to get that soon.
I have a question for you about the npernode option. I am assuming that you
want n procs/
GM: gm_register_memory will be able to lock XXX pages (YYY MBytes)
Is there a way to tell GM to pull more memory from the system?
GM reserves all IOMMU space that the OS is willing to give it, so what is
needed is a way to tell the OS and/or machine to allow a bigger chunk of
IOMMU space to b

Hello all,
I am a user of R and have been having trouble with LAM/MPI. I am curious as
to whether OpenMPI would be a good option for me to try instead. However, I
am unsure as to whether OpenMPI and R can be used together. Can someone
tell me whether OpenMPI can be used with R or not? If so, c
