RE: [ptp-user] New MPICH2 resource manager support
Hi Greg,
 
I have installed the latest build(March 5th).  It seems to behave a lot better but when I still run my parallel configuration using an MPI project or a Remote C project the rdt server throws the following exception:
 
java.io.IOException: Stream closed

I can connect using RTD to my remote server and start my resource manager without any problems but when I run my parallel config it's when i get the ex above.
 
Please advise.
 
Thanks,
Alex

Hi Alex,

PTP 2.1.1 doesn't use a proxy for Open MPI or MPICH2 any more, so you should only see the sdm. The MPICH2 RM does not automatically start the mpd's, so you need to do that manually.

Please check that you can manually run an MPI job on the machine (using the 'mpirun' command). 

To check how many nodes you should see, run the command 'mpdtrace -l'.

If either of these commands indicate there are problems, you'll need to correct them first.

Greg

Greg,
I have tried the latest ptp version 2.1.1 using mpich but I haven't had any success.  I did noticed that when I installed the ptp server components in my remote machine and ran the "sh Build command"  I only had the sdm executable(no proxy exe - I'm guessing this part of the upgrade 2.1.1).
 
Before running my parallel configuration I did the following:
-created a remote c Mpich project
-ran my rdt server in my remote machine
-connected within eclipse to my remote system
-I had to run manually my mpd(mpich) exe
-Ran my resource manager
 
When I started the resource manager using mpich2-1.0.5p4 I was able to see the machine a one root node(node 0).  When I tried to launch my parallel program I did see my job but there was no root info in my job view.
 
Please advise.
 
Thanks a lot,
Alex

Hi,

The 20 Jan build of PTP 2.1.1 now includes a preliminary version of a  
new resource manager for MPICH2. The MPICH2 resource manager no longer  
requires a direct connection to MPD, so should theoretically work with  
any version of MPICH2 (I've tested with 1.0.8). It also supports  
debugging of MPICH2 applications!

To install, follow the 2.1.0 release notes here: http://wiki.eclipse.org/PTP/release_notes/2.1
.

A link to the build is available here: http://wiki.eclipse.org/PTP/builds/2.1.1

Note: this is a pre-release version, so you may encounter bugs.

Regards,

Greg
