Hi,
Would you please recommend a debugger, which can do debugging for parallel
processes on Open MPI systems ?
I hope that it can be installed without root right because I am not a root user
for ourMPI cluster.
Any help is appreciated.
Thanks

Hi,
I tried to build Open MPI 1.5 on Solaris X86 and x86_64 with Oracle
Studio 12.2. I can compile Open MPI with thread support, but I can
only partly install it because "libtool" will not find "f95" although
it is available. "make check" shows no failures.
tyr openmpi-1.5-SunOS.x86_64.32_cc 188
Hello. I'm try to build orcm , in dependencies it need openmpi trunk
with some options have been enabled.
Install fails with message:
Creating orte-migrate.1 man page...
x86_64-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I../../../opal/include
-I../../../orte/include
-I../../../opal/mca/paffinity/hwloc/
Sorry, but can you give us the config line, the config.log and the
full output of make preferrably with make V=1?

I'd suggest looking into TotalView (http://www.totalviewtech.com) and/or DDT
(http://www.allinea.com/). I've used TotalView pretty extensively and found
it to be pretty easy to use. They are both commercial, however, and not
cheap.
As far as I know, there isn't a whole lot of open source support
Couple of things stand out:
1. you definitely don't want to use a copy of the trunk beyond r23924. The
developer's trunk is undergoing some major change and orcm no longer is in-sync
with it. I probably won't update orcm to match until later this year (will
freeze integration at r23924).
2. th
I find that using mpirun to launch multiple instance of a serial
debugger is fairly usable (but not perfect) for jobs with fewer than
about four processes.
A description of how to do this is here:

The biggest drawbacks to this approach are that

Hi list,
I'm sorry to bother you with a stupid question.
we intend to have for a short period of time, some nodes with 1.4.3 and
others with 1.4.1 (before upgrading everyone to 1.4.3).

releases in a given feature series and its corresponding super-stable series

I guess we will play it safe and upgrade every cluster at once so that
we won't get bad surprises.
thank you Jeff.

thanksI have run padb (the new one with your patch) on my system and got
:-bash-3.2$ padb -Ormgr=pbs -Q 48516.cluster$VAR1 = {};Job 48516.cluster is
not activeActually, the job is running.
How to check whether my system has pbs_pro ?
Any help is appreciated. thanksJinxu DingOct. 29 2010

Can you try the following and send me the output.
qstat -n -u `whoami` @clusterName
The output sent before implies that your cluster is called "clusterName" rather
than "cluster" which is a little surprising but let's see what it gives us if
we query on that basis.

Hi,
this is what I got :
-bash-3.2$ qstat -n -u myName
clsuter:

Not without a list of hostnames it's not any use no, if you can get that, then
I have something to work with. From looking around on google -n might help
here. Once I have this info you'll need to verify that you are able to ssh to
these nodes without a password, that pdsh is installed and gi
