PS - Kritiraj
Reading your message more carefully, I saw that you did
this:
****
Open the $HOME/.bashrc and added the following:
PATH="/usr/local/include:$PATH"
LD_LIBRARY_PATH="/usr/local/lib:$LD_LIBRARY_PATH"
****
However, this is what you should have done:
****
Open the $HOME/.bashrc and added the following:
PATH="/usr/local/bin:$PATH"
LD_LIBRARY_PATH="/usr/local/lib:$LD_LIBRARY_PATH"
****
Note that /usr/local/bin, not /usr/local/include should be
pre-pended to your PATH!

Hi Kritiraj
This looks like as many other errors reported on this
list
that are caused by using the wrong MPI compiler
wrappers
or the wrong mpirun/mpiexec.
Typically this is caused by a PATH environment
variable that
is pointing to the wrong executables (mpicc, mpirun).
Most Linux distributions, compilers, etc, come with
their
own MPI versions, and this can be very confusing.
Try using full path names for mpicc and for mpirun.
That is bullet proof method to get exactly what you
want.
In your case use /usr/local/bin (as you configured
with --prefix=/usr/local).
(Actually, I prefer to configure with a more
distinctive
name to the prefix, something like
/usr/local/openmpi-1.3.2,
to avoid any confusion with other MPIs.)
You can also try "which mpicc" and "which mpirun",
or "mpicc --showme" and "mpirun --help" to get a bit
more
information about what you are really using.
I hope this helps.

Dear All,
I
have install and configured openmpi with BLCR on my laptop:
1) configure and install blcr
./configure --prefix=/usr/local/
--enable-debug=yes --enable-libcr-tracing=yes
--enable-kernel-tracing=yes --enable-testsuite=yes
--enable-all-static=yes --enable-static=yes
make
make install
2) configure and install openmpi
./configure --prefix=/usr/local/ --enable-picky
--enable-debug --enable-mpi-profile --enable-mpi-cxx
--enable-pretty-print-stacktrace --enable-binaries
--enable-trace --enable-static=yes --enable-debug
--with-devel-headers=1 --with-mpi-param-check=always
--with-ft=cr --enable-ft-thread --with-blcr=/usr/local/
--with-blcr-libdir=/usr/local/lib --enable-mpi-threads=yes
make all install
3) add the environment variables.
Open the $HOME/.bashrc and added the following:
PATH="/usr/local/include:$PATH"
LD_LIBRARY_PATH="/usr/local/lib:$LD_LIBRARY_PATH"
Now the problem:
I am trying to checkpoint the following MPI
application:
#include <stdio.h>
#include <mpi.h>
main(int argc, char **argv)
{
int node;
MPI_Init(&argc,&argv);
MPI_Comm_rank(MPI_COMM_WORLD,
&node);
printf("Hello World from Node
%d\n",node);
MPI_Finalize();
}
I am running mpirun as follows:
raj-laptop> mpirun -am ft-enable-cr
helloworld.
The errors are as follows:
--------------------------------------------------------------------------
It looks like opal_init failed for some reason;
your parallel process is
likely to abort. There are many reasons that
a parallel process can
fail during opal_init; some of which are due to
configuration or
environment problems. This failure appears
to be an internal failure;
here's some additional information (which may only
be relevant to an
Open MPI developer):
opal_cr_init() failed failed
--> Returned value -1 instead
of OPAL_SUCCESS

Is it something to do with me running it on a
single node; i.e my laptop? or is it something to do with
configurations or libraries?
Any help will be very appreciated.
