Hello,
I've integrated DMTCP (1.2.4 on Fedora 16 and Ubuntu 11.10) with Grid Engine
(https://arc.liv.ac.uk/trac/SGE and http://gridscheduler.sourceforge.net/)
and I've come across a curious problem.
I've made my lap top a Grid Engine master, execution host and submission host,
and have created two queues. When I submit a job to Grid Engine asking for
DMTCP checking, everything works fine - checkponting, re-starting,
re-checkpointing, re-re-starting, ... - as long as the job runs in the same
queue. However, when I checkpoint and kill a job and force it to re-start on
another queue, checkpointing that re-started job doesn't work. When the system
initiates a checkpoint, the job core-dumps and issues the error message
[3308] mtcp.c:2333 perform_callback_write_ckpt_header:
error 2 creating temp file: No such file or directory
[3313] mtcp.c:2333 perform_callback_write_ckpt_header:
error 2 creating temp file: No such file or directory
and the checkpoint command used (dmtcp_command -bc) has 99 as its exit status.
N.B.: This job is re-starting on the same host, just in a different Grid Engine
queue from the original job.
I'll be grateful for any suggestions.
