Re: [ptp-user] Problem Using MPICH2 With Eclipse PTP

Hi Martin,
Looks like you're mixing some old and some new PTP features.
The Parallel Runtime Perspective and the starting a "resource manager" explicitly are now deprecated in favor of setting a "target system configuration" (yet we still sometimes call it a "resource manager") on the run configuration dialog and monitoring the run in the "System Monitoring Perspective."

Can you confirm your version of PTP?
The latest release is  6.0.3.201211112147
So I'm guessing you are running ok with the old resource manager framework but the new one isn't working.

Do you mean "in the run configuration dialog" instead?
Note that to run on a local machine you (currently) have to create an ssh connection back to localhost.

The perl scripts should get moved to .eclipsesettings automatically .... altho I'm not an expert on that matter.
Just wanting to clarify some things so others can perhaps answer other details.

Hello,
 
I’m a new PTP user, so please forgive me if this is dumb question.
 
I’m using the latest versions of PTP and MPICH2 running on Centos 6. 
 
I have built and run the C++ CPI example project on  my local machine from the Parallel Runtime perspective. This seems to work OK as I get a value of pi output to the Console. I can also change the number of processes used – success so far!
 
OK, so I’d like to be able to set up a Resource Manager for MPICH2, so I created an MPICH2-Generic-Interactive instance using the Resource Manager tab in the Parallel Runtime perspective. When I start it, I get an error:
 
Problem Occurred
‘LML DA Driver (connection name)’ has encountered a problem.
Server finished with exit code 1
 
After a little digging, I found the report.log file in the $HOME/.eclipsesettings/tmp_<host>_<pid> directory, containing the following error:
 
LML_da_driver.pl: found rms/MPICH2/da_check_info_LML.pl running test ...
LML_da_driver.pl:  ERROR could not run rms/rms/MPICH2/da_check_info_LML.pl (perhaps missing return code of script)
 
I checked my $HOME/pi/.eclipsesettings/rms/MPICH2 directory and it only contains start-job.pl. I compared the contents of this directory with the others in rms and found that they also contain other perl scripts, including the one that appears to be missing from MPICH2 (da_check_info_LML.pl).
 
So, my questions are:

1)      Are some of the perl scripts missing from $HOME/pi/.eclipsesettings/rms/MPICH2 or do they exist somewhere else?
2)      If they are missing, is there also a bug in the script existence check in LML_da_driver,pl which shows up the in the first line of the log output above, since it reports that it found rms/MPICH2/da_check_info_LML.pl but it doesn’t actually appear to exist.

I tried this with the both the latest Eclipse Juno PTP installation and also with the latest Juno PTP update and got the same issue.
 
Thanks in advance for any help you may be able to give.
 
Martin
