MPI debugger settings for VS 2008

Tue, 10 Mar 2009 02:27:56 Z

I would be very grateful to you for any help with MPI debugger settings.

This is the story:

1) I have a VS 2008 project set for an MPI executable like this:

MpiRun Command: mpiexec
MpiRun Arguments: -job 64.0 -hosts 3 AUSYDTSS011 3
Appp command: C:\TFS\RAV2\RAP\Prototypes\HPC\RADA\RECA Prototype\MpiSingleTaskletRun\bin\Debug\MpiSingleTaskletRun.exe
MPIShim loc: mpishim.exe

(the rest as per MS recommendations)

2) This is how I have submitted a job for scheduler:

C:\>job submit /numprocessors:3 /requestednodes:AUSYDTSS011 /runtime:00:06:00 /rununtilcanceled:true /scheduler:AUSYDTSS010

Job has been submitted. ID: 64.

C:\>job view /scheduler:AUSYDTSS010 64

Id : 64

State : Running

Name :

Project Name :

Owner : TSSLAB\aronovv

Template : Default

Priority : Normal

Resource Request : 3-3 cores

Type : Batch

Node Groups :

Requested Nodes : AUSYDTSS011

Allocated Nodes : AUSYDTSS011

Current Allocation : 3 cores

Submit Time : 10/03/2009 11:12:53 AM

Start Time : 10/03/2009 11:12:53 AM

End Time :

Elapsed Time : 00:00:51:57

Wait Time : 00:00:00:00

Run As : TSSLAB\aronovv

Pending Reason :

Error Message :

Task Count : 0

Configuring tasks : 0

Queued tasks : 0

Running tasks : 0

Finished tasks : 0

Failed tasks : 0

Canceled tasks : 0

3) Nevertheless I got the following when I have started debugging from the head node of the cluster (AYSYDTSS010):

Aborting: Access denied by node 'AUSYDTSS011'.

mpiexec is attempting to use this node which was not allocated to job '64.0' by

the Microsoft HPC Scheduler.Press any key to continue . . .

4) When I removed -job clause from the project settings and set CCP_TASKCONTEXT=64.0:

C:\Users\aronovv>set CCP_TASKCONTEXT

CCP_TASKCONTEXT=64.0

it was even worse:

Aborting: Access denied by node 'AUSYDTSS011'.

This node is a resource managed by the Microsoft HPC Scheduler and mpiexec was attempting to use it without a scheduled job.Press any key to continue . . .

What would you suggest?

Regards and many thanks,

Valery

BTW: Another problem - my attempt to set a shared resource for 'Application Command' and 'Working Directory' was rejected: CMD does not support UNC names. Many MS examples on-line have UNC settings there. How to fix it? V.
