Hi Manuel,
Thanks for pointing this out. The problem was that while
'dmtcp_launch --quiet' made the launch process quiet, the
dmtcp_coordinator was not being quiet. I've now put up a branch
on github for review in which 'dmtcp_launch --quiet' passes the '--quiet'
flag onto the 'dmtcp_coordinator', and the coordinator obeys that flag.
It will be under review for a few days, but you can try it out now by calling:
git clone -b quiet-coordinator https://github.com/gc00/dmtcp.git dmtcp-quiet
[ Since this is going to dmtcp-forum, if someone is reading this in the
future this branch will go away, and the functionality will be
merged into the main DMTCP branch. ]
Best,
- Gene
