Dear all,
I had to try the checkpoint/restart function of Openmpi recently, and after
several failure and checking lots of the docement, I am still very confused
about how to config the checkpoint/restart function. Can anybody give me a
$HOME/.openmpi/mca-params.conf script and introduce me what p
My main question is:
after I finished the checkpoint operation against a simple task which ran on
tow machines, I can only restart it on one machine. if I ran the following
command to force the ompi-restart to run the program on two machines:
*ompi-restart -hostfile ./machine_names ompi_global

Can anyone point me towards the most recent documentation for using
srun and openmpi?
I followed what i found on the web with enabling the MpiPorts config
in slurm and using the --resv-ports switch, but I'm getting an error
from openmpi during setup.
I'm using Slurm 2.1.15 and Openmpi 1.5 w/PSM
I'm not sure there is any documentation yet - not much clamor for it. :-/
It would really help if you included the error message. Otherwise, all I can do
is guess, which wastes both of our time :-(
My best guess is that the port reservation didn't get passed down to the MPI
procs properly - but
Dear all,
I have figured it out. It was a simple issue, I didn't add the "blcr lib" to
the $PATH environment varable. However, it can make checkpoint operation,
but can't make restart operation successfully. It was so wield.
