We are facing another problem, we were tryin to install different
benchmarking packages
now whenever we try to run *mpirun* command (which was working perfectly
before) we get this error:
*usr/local/bin/mpdroot: open failed for root's mpd conf filempdtrace
(__init__ 1190): forked process failed; s
i feel the above problem occured due 2 installing mpich package, now even
nomal mpi programs are not running.
What should we do? we even tried *yum remove mpich* but it says no packages
to remove.
Please Help!!!

Hi,
I am running MPI alltoall test on my 8nodes cluster. They all have
24core cpus.
So total number of processes that I am running is 8*24=192. In summary,
alltoall test on 8nodes and 24 processes per node.
But, my test consumes all RAM and swap space memory. However, if I count

Your calculation looks correct, the conclusion is slightly wrong
however. The Application buffers

Did you mean 1.1.3 or 1.3.1?

Hi Ankush
I second Eugene's comments.
I already sent you on previous emails to this thread
all relevant information on where to
get HPL from Netlib (http://netlib.org/benchmark/hpl/),
Goto BLAS from TACC (http://www.tacc.utexas.edu/resources/software/),
and the standard BLAS from Netlib (http://
Hi
This is a MPICH2 error, not OpenMPI.
I saw you sent the same message to the MPICH list.
It looks like you are mixed both MPI flavors.

Hi
Do "yum list | grep mpi" to find the correct package names.
Then uninstall them with "yum remove" using the correct package name.
Don't use yum to install different flavors of MPI.
Things like mpicc, mpirun, MPI libraries, man pages, etc,
will get overwritten in /usr or /usr/local.

It looks like something must not be right in your password-less ssh
setup. You need to be able to "ssh cluster-srv2.logti.etsmtl.ca
uptime" and have it not ask for a password. Are you able to do that?

I am trying to get the checkpoint/restart to work on a single machine

Incidentally, if I add a check for the value base->sig.sh_old, that it
is not NULL, and recompile, everything works fine. I am concerned this
is just fixing a symptom rather than the root of the problem.

is what I used.

It looks like you need to fix your password-less ssh problems first:

Hi Luis, list
To complement Jeff's recommendation,
see if this recipe to setup passwordless ssh connections helps.
If you use RSA keys instead of DSA, replace all "dsa" by "rsa":

I hope this helps.

thank you all, I'll try to fix this ASAP, after I'll make a new test
round than I answer back, Thanks you all until here.

Hi,
I've never done this, but I believe that an executable compiled with
profilling support (-pg) will generate the gmon.out file in its current
directory, regardless of running under MPI or not. So I think that
you'll have a gmon.out on each node and therefore you can "gprof" them

Hi,
Yes you can profile MPI applications by compiling with -pg. However, by
default each process will produce an output file called "gmon.out",
which is a problem if all processes are writing to the same global file
system (i.e. all processes will try to write to the same file).
There is an
There is a tool (not free) That I have liked that works great with
OMPI, and can use gprof information.

Also I am not sure but Tau (which is free) Might support some gprof
hooks.

Hi,
Any body know how to make use of shared memory in OpenMPI implementation?
Thanks
Shared memory is used for send-to-self scenarios such as if you're
making use of multiple slots on the same machine.

Dear Jeff
Thanks for your help.
Unfortunately, after I thoroughly examined entire cluster, I found a bad
node with busted hard drive. That's the reason why this job hanged.
Also, when this job is sent with one bad node among the machinefile, neither
