Intel MPI, perhost, and SLURM: Can I override SLURM?


(Note: I'm also asking this on the slurm-dev list.)

I'm hoping you can help me with a question. Namely, I'm on a cluster that uses SLURM and lets say I ask for 2 28-core Haswell nodes to run interactively and I get them. Great, so my environment now has things like:


Now, let's run a simple HelloWorld on, say, 48 processors (and pipe through sort to see things a bit better):

mpitune get "could not dump the session, because unknown encoding: utf-8"

Hi forum,

I try the following command on a server: (impi, icc 2015.2.164)

mpitune -of analysis.conf -application \"mpirun -n 24 -host `hostname` ./myexe\"

It did run for a while but output nothing of analysis.conf. Meanwhile the console output message like:

ERR | Could not dump the session, because unknown encoding: utf-8

I try to change LANG=C, as locale outputs:



...(all other environment variables are "C")

Intel MPI and Windows firewall on localhost

Hi everybody,

We run mpiexec on Windows 7 on multiple network installations of our product in the following manner:

mpiexec.hydra.exe -np x -localroot -delegate -localonly -localhost one_path_to_EXECUTABLE

The problem is with the windows firewall (which is executable path triggering) and alerts, because mpiexec.hydra.exe and pmi_proxy.exe do a listen on

Is there an option / environment variable available to tell mpiexec.hydra only listen on instead of all available interfaces if we run it only local on one workstation.

open_hca: getaddr_netdev ERROR: Connection refused. Is ib0 configured ERROR

Dear all,

I am a beginner in linux; i am using quantum espresso software; The cluster we have at University has three types of partition short (for jobs within an hour), long (jobs within 4 days) and superlong (jobs within 10 days). each node has 8 processors; however recently when I am running a job, only the SHORT partition works properly; this is not very useful for me as I need to run longer jobs. when i run the other two (long and superlong) I get several errors: running on more than one node say : 16 processors (2 nodes) producesan error:
