Thanks for the replies guys! Definitely two suggestions worth trying.
Definitely didn't consider a derived datatype. I wasn't really sure that the
MPI_Send call overhead was significant enough that increasing the buffer
size and decreasing the number of calls would cause any speed up. Will
change t
Wouldn't you need to create a different datatype for each matrix
instance? E.g., let's say you create twelve 5x5 matrices. Wouldn't you
need twelve different derived datatypes? I would think so because each
time you create a matrix, the footprint of that matrix in memory will
depend on the w
Hi All,
I got a problem when trying to checkpoint a mpi job.
I will really appreciate if you can help me fix the problem.
the blcr package was installed successfully on the cluster.
I configure the ompenmpi with flags,
./configure --with-ft=cr --enable-ft-thread --enable-mpi-threads
--with-blcr=/
Even with the original way to create the matrices, one can use
MPI_Create_type_struct to create an MPI datatype (http://web.mit.edu/course/13/13.715/OldFiles/build/mpich2-1.0.6p1/www/www3/MPI_Type_create_struct.html
) using MPI_BOTTOM as the original displacement.

Hi Basant,
I am not familiar with Windows builds of Open MPI. However, can you see
if you Open MPI build actually created a mca_paffinity_window's dll? I
could imagine the issue might be that the dll is not finding a needed
dependency. Under Windows is there a command similar to Unix's ldd
Hi Konstantinos, list
If you want "qsub" you need to install the resource manager /
queue system in your PC.
Assuming your PC is a Linux box, if your resource manager
is Torque/PBS on some Linux distributions it can be installed
from an rpm through yum (or equivalent mechanism), for instance.

good part of the day,
I am trying to run a parallel program (that used to run in a cluster) in my
double core pc. Could openmpi simulate the distribution of the parallel jobs
to my 2 processors meaning will qsub work even if it is not a real cluster?
thank you for reading my message and for an
Terry,
you were right! Thanks a lot - I never thought about double checking the
bitness :)
Now it compiled fine. All I have to do is check if the program works ... but
that is something between me and the developers.
Any remarks on the options I handed to the compiler? It worked with them but

Terry,
Thanks for your input so far. I'll try changing the compiler to the 64bit
version. I might have been mistaken to assume that my openSuse is a 32bit
system when in fact it could well be 64bit (which might explain why Open MPI
installed the 64bit library after the system check).
The configure
Also, is the configure line you are giving below the application
configure line. I was actually asking for the Open MPI configure line.

Let me try this one more time.
Your application is being built with a 32 bit compiler ia32. However
the Open MPI libraries look to be built with the 64 bit compiler
intel64. One or the other needs to change.

Georg,
I think your problem is you are using a ia32 (32 bit compiler) with a 64
bit built library. Either you need to use the intel64 compiler or build
Open MPI with the 32 bit library.

A copy of the configure line for Open MPI would be helpful. Which Intel
compiler are you using, version and bitness. Can you do file on
libmpi_f77.so? Also, are you sure that /usr/local/lib is where you
installed you Open MPI build and that isn't something latent?

Hi!
Im trying to compile a Fortran file. I did not code it myself and am not

result in after compiling.
Along with the file I also received a command line.

Ok, thanks for you advises. Actually I did not install BLCR... As I
have told I was unable to find proper documentation and I just thought
it is all included :)
I will try to see what is each parameter for and I will install OpenMPI once
again.
Thanks again,

Hi Andreea,
I compiled an installation of openmpi with checkpoint/restart support
and it is working fine and I'm trying to integrate it with SGE.
Did you set the right option compiling openMPI?
Did you installed BLCR before?
I used these options:
./configure --prefix=/opt/cesga/openmpi-1.3.3
Hi,
I'm a newbie, and I want to test the checkpoint/restart mechanism included in
OpenMPI v 1.3.3. I have tried to search for some documentation about how to
install the OpenMPI implementation in order to support checkpoint/restart, and
I found lots of links to
