Dear OMPI Users,
I’m now using BLCR-0.8.2 and OpenMPI-1.5rc5. The problem is that it takes a
very long time to checkpoint.
BLCR configuration:
./onfigure --prefix=/opt/blcr --enable-static
OpenMPi configuration:
./configure --prefix=/opt/ompi --with-ft=cr --with-blcr=/opt/blcr
--enable-s
Dear OMPI Users,
I have installed BLCR(0.8.2) and OpenMPI(1.4.2) successfully. But now I met
a problem when I take a checkpoint.
I run CG NPB(NPROCS=16, two nodes: blade02 & blade04, CLASS=C, NFS: $HOME &
/opt are shared)
BLCR configure: ./configure �Cprefix=/opt/blcr �Cenable-static

I was so careless. BLCR Admin Guide says: as the root, load the kernel
modules in this order:
# /sbin/insmod /usr/local/lib/blcr/2.6.12-1.234/blcr_imports.ko
# /sbin/insmod /usr/local/lib/blcr/2.6.12-1.234/blcr.ko
In the last email, I load the kernel in the wrong order. And I followed the

I really thank you for your advice, Josh. As you say, when check 'lsmod |
grep blcr' on blade02, nothing shows. That means no blcr module is inserted
on blade02. I think that's the main reason why I can't C/R mpi programs on
these two nodes.
But here is the problem:
I installed blcr under /opt/blcr
Dear OMPI users,
I configured and installed OpenMPI-1.4.2 and BLCR-0.8.2. (blade01 �C
blade10, nfs)
BLCR configure script: ./configure �Cprefix=/opt/blcr �Cenable-static
After the installation, I can see the ‘blcr’ module loaded correctly
(lsmod | grep blcr). And I can also run ‘cr_run’, ‘cr_
