<br>
Sorry, I haven't written up the documentation on this yet. You'll need to install BLCR, and configure mpich2 with the following configure options:<br>
<br>
--with-hydra-ckpointlib=blcr --enable-checkpointing<br>
<br>
If you didn't install BLCR in a standard system location (e.g., if you installed it in your home directory), then you'll need to specify the install location using the --with-blcr= configure option as well. Also, make sure that your LD_LIBRARY_PATH is set correctly if necessary.<br>
<br>
Once you configure and make, you'll need to make sure the BLCR kernel modules are loaded on each machine. Use the -ckpoint-interval option for mpiexec to specify how often to take checkpoints. You'll also need to specify the location where the checkpoint files should be written using the -ckpoint-prefix option (make sure the directory exists).<br>
<br>
To restart from a checkpoint specify the same number of processes as the original run and the -ckpoint-prefix option, but leave off the name of the executable.<br>
<br>
Let us know how this works for you. Remember that you're using a beta version, so you might still encounter some bugs.<br>
