Dear all members,<br><br>I have some question. But first, I've installed MPICH2 in my cluster (11 computers).<br>It is my cluster specification :<br>-Debian 5<br>-MPICH2-1.3a2 (by download the package)<br>and BLCR package hasn't installed yet<br>
<br>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. <br>I have try to modify it in one week, but it didn't give significant progress.<br>
So, my question are :<br>1. Is it true that blcr have already embedded in MPICH2-1.3a2 package?<br>2. ckpoint_blcr.c calls many standard cr function. And I've succesfully run checkpointing MPICH2 standard mechanism for my MPI program.<br>
But I didn't find the file that contain definintion of cr_checkpoint, cr_poll_checkpoint, and others. Where can I find ?<br>3. Where is the location of libcr.h? ckpoint_blcr.c call this function. Do I need to install BLCR package first?<br>
4. Do nyone have idea how to modify blcr mechanism in MPICH or how to create our checkpoint/restart mechanism?<br><br>Please answer my question. Thank you so much for your attention.<br><br>Best regards,<br>Bagus<br>
