Dear,
It seems to me you are trying to parallelize following a Master/Slave
paradigm.
Perhaps you may want to take a look and test some existing MPI-based
library for achieving that:
- DMSM: https://www.hpcvl.org/faqs/dmsm-library
- TOP-C: http://www.ccs.neu.edu/home/gene/topc.html
- ADLB: https:

Just as Ralph said,
Hi Paul,
can you give us some additional information
- on your compilation command line ?
- the application you're trying to run ?
Just in case, did you try checking points 1. and 2. of the error message
in the application you're trying to run ?

Hi Alexander,
Indeed the link is inaccessible. If you try only
http://webct.ncsa.uiuc.edu
you get redirected to http://www.citutor.org/login.php
You need registering to access the tutorial materials.
A preview of available materials appears in

Hi,
you may start by looking at http://www.open-mpi.org/faq/?category=ft
which leads you to
https://svn.open-mpi.org/trac/ompi/wiki/ProcessFT_CR
and
http://osl.iu.edu/research/ft/ompi-cr/
The latter is the most up-to-date link and probably what you are looking
for.

Assuming the type of the elements in the array is known, you'll probably
have to do it in two steps:
1) Broadcast the number of elements in the array
2) Broadcast the array itself

The same way as mpicc. Actually on my machine they both are symlinks to
"opal_wrapper".
Your second screenshot suggests orte* commands have been installed.

Hi,
Did you try ortecc command directly ?
Perhaps the RPM package you're installing does not create symlinks from
ortecc to mpicc ...

Hi everyone !
I have started playing a little bit with Open MPI 1.5.3 and
came across the " --with-ft=LAM " option in the ./configure script.
However, I did not find its meaning anywhere in the doc ...
Best regards,

Concerning the mca options for checkpointing:
- are verbosity options (e.g.: crs_base_verbose) limited to 0 and 1
values ?
- in priority options
Hi,
from what you describe below, seems as if you did not configure well
OpenMPI.
You issued
./configure --with-ft=cr --enable-mpi-threads --with-blcr=/usr/local/bin
--with-blcr-libdir=/usr/local/lib
while according to the installation paths you gave it should have been
more like
./confi
.open-mpi.org/trac/ompi/wiki/ProcessFT_CR
Additionally this has been addressed on the users mailing list in the
past, so searching around will likely turn up some examples.

Dear all,
I have installed blcr 0.8.2 and Open MPI (r21973) on my NFS account. By
default,
it seems that checkpoints are saved in $HOME. However, I would prefer them
to be saved on a local disk (e.g.: /tmp).
Does anyone know how I can change the location where Open MPI saves
checkpoints?
