[mpich-discuss] Asking standard checkpoint in MPICH2

[Bagus Jati Santoso]

Dear all members,

I have some question. But first, I've installed MPICH2 in my cluster (11
computers).
It is my cluster specification :
-Debian 5
-MPICH2-1.3a2 (by download the package)
and BLCR package hasn't installed yet

Since websites said that there is BLCR-based checkpointing feature in
standard MPICH2, I want to do little modification with BLCR mechanism in
MPICH2-1.3a2.
I have try to modify it in one week, but it didn't give significant
progress.
So, my question are :
1. Is it true that blcr have already embedded in MPICH2-1.3a2 package?
2. ckpoint_blcr.c calls many standard cr function. And I've succesfully run
checkpointing MPICH2 standard mechanism for my MPI program.
     But I didn't find the file that contain definintion of cr_checkpoint,
cr_poll_checkpoint, and others. Where can I find ?
3. Where is the location of libcr.h? ckpoint_blcr.c call this function.  Do
I need to install BLCR package first?
4. Do nyone have idea how to modify blcr mechanism in MPICH or how to create
our checkpoint/restart mechanism?

Please answer my question. Thank you so much for your attention.

Best regards,
Bagus
