<meta http-equiv="Content-Type" content="text/html; charset=utf-8"><div dir="ltr">Good afternoon all,<div><br></div><div>I am a newbie in this MPICH world. I am trying to install a cluster with MPICH, having the possibility of checkpoint parallel tasks.</div><div><br></div><div>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.</div><div><br></div><div>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 <a href="https://wiki.mpich.org/mpich/index.php/Checkpointing">https://wiki.mpich.org/mpich/index.php/Checkpointing</a></div><div><br></div><div>However, when looking for the solution I found this thread in this same mailing list:</div><div><a href="http://lists.mpich.org/pipermail/discuss/2014-April/002498.html">http://lists.mpich.org/pipermail/discuss/2014-April/002498.html</a><br></div><div><br></div><div>saying " BLCR checkpointing hasn't worked for a few versions now. It's something we're working to fix in a future version". </div><div><br></div><div>My question is then,</div><div><br></div><div>-Is it possible right now to checkpoint MPICH with BLCR?</div><div><br></div><div>-If not, is there any working checkpoint mechanism that you can suggest me?</div><div><br></div><div>-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?)</div><div><br></div><div> Thanks for your attention.
