Hi all,
This is my fourth mail regarding the "installing lam with blcr". Except
the first one nobody has replied the mails. I hope this time somebody will
reply me soon.
Now LAM/BLCR is working fine in single node. But in cluster when i try to
run the sample programme hello.c following error comes, after compiling
the hello.c
$mpirun N hello
hello: error while loading shared libraries: libcr.so.0: cannot open
shared object file: No such file or directory
-----------------------------------------------------------------------------
It seems that [at least] one of the processes that was started with
mpirun did not invoke MPI_INIT before quitting (it is possible that
more than one process did not invoke MPI_INIT -- mpirun was only
notified of the first one, which was on node n0).
mpirun can *only* be used with MPI programs (i.e., programs that
invoke MPI_INIT and MPI_FINALIZE). You can use the "lamexec" program
to run non-MPI programs over the lambooted nodes.
-----------------------------------------------------------------------------
Although as i told earlier program runs with no error in a single node
cluster, i have checked it individually with all nodes.I have checked the
lam/mpi mailing-list but i am not able to find out the problem.
For your information, previously when i installed BLCR i gave following
command to confiure the blcr
$ ./configure --with-linux=/usr/src/linux-2.4.20-8/
--with-system-map=/boot/System.map --prefix=/home/BLCR
BLCR directory contains lib subdir* which further contains blcr subdir*
and all lib.* files.
Now i configure lam/mpi with the following command
$ ./configure --with-blcr=/home/BLCR --with-rpi=crtcp --with-rsh="ssh -x"
then..
$ make
$ make all install
I have added following lines in .bash_profile
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/BLCR/lib
export LD_LIBRARY_PATH
and output of
$laminfo
