Hi Sebastien,
I have a question concerning the usage of the checkpoints options.
I have run one big analysis using 40 nodes of 12 cores using the
-write-checkpoints option.
So like I was guessing, I didn't have enough time to complete the job. The
thing is now that when I relaunch the analysis with the
-read-write-checkpoints option, all the nodes are crashing.
Here's an example :
[node-c3-79:27010] *** Process received signal ***
[node-c3-79:27010] Signal: Segmentation fault (11)
[node-c3-79:27010] Signal code: Address not mapped (1)

Could this be because I'm not reserving the same number of processors as
the first analysis?
Thanks for your help.
