Good afternoon all, I am a newbie in this MPICH world. I am trying to install a cluster with MPICH, having the possibility of checkpoint parallel tasks. My original idea was a software stack based on SLURM 14.03.8 + MPICH mpich-3.1.3 + BLCR 0.8.5 . They are supposed to have good integration among them, and the configuration process has been quite smooth until now. I have found however that the checkpoint of MPICH tasks is not working. At first I though it was my fault (configuration issues or whatever) due to it can be read in MPICH home page that BLCR integration is possible https://wiki.mpich.org/mpich/index.php/Checkpointing However, when looking for the solution I found this thread in this same mailing list: http://lists.mpich.org/pipermail/discuss/2014-April/002498.html saying " BLCR checkpointing hasn't worked for a few versions now. It's something we're working to fix in a future version". My question is then, -Is it possible right now to checkpoint MPICH with BLCR? -If not, is there any working checkpoint mechanism that you can suggest me? -If not, are you aware of a previous MPICH version where BLCR does work? Are there any drawbacks on employing it while you get the new one fixed? (Are you getting the new one fixed?) Thanks for your attention.
