Using Intel MPI on Windows HPC cluster manager

gert_massa — Wed, 09 Jun 2010 08:51:07 GMT

Hi All,

In the Intel MPI manual it says it is supported on Windows HPC am unable to run my MPI application using the HPC cluster nanager.

My observations:

- When I select the resources based on number of nodes equal to 1 but not using mpi (ie. running my application sequencially) it works fine.
- When I select the resources based on cores but not using mpi (ie. running my application sequencially) it only works when I specify to number of cores equal to the physical cores of my system. Ie. on a quad core it works when I secify 4 core but doesn't work for 1, 2 or 3
- when I want to user mpi and I add mpiexec to my command i get the folowing error
[01:4792]....ERROR:unable to read the cmd header on the pmi context, Error = -1

Does anyone have some experience with Intel mpi and windows HPC?

Thanks in advance!

Hi Gert,

I think that we need more information about your environment and your task.

First of all: what version of the Intel MPI Library do you use?
Have you tried to run HelloWorld example from the test directory of the Intel MPI installation?

Does smpd service work on your nodes? Please run 'smpd -status .

What is your application and how you run it?

Let's start from this information and I hope that we will be able to help you.

Regards!
Dmitry

Hi Dmitry,

I've downloaded the last MPI version 4.0.0.012 but still have the same problem as I had with version 3.2.1.009. I am able to run a small test apllication I wrote myself but my real application needs to be lauched from a bat file (setting some environment variables) which might cause some problems. Although doing the same thing using the microsoft mpi works fine. I have a contact at microsoft which helped me to find the cause of the problem but he found out there is a crash happening in impi.dll because of a division by zero.

Strangely I do not need to run my application in parallel to have this error. Ie not using mpiexec.

See below the stack trace

(a1c.6b4): Integer divide-by-zero - code c0000094 (first chance)
