HI,
I am running a set of few hundred simulations with NAMD. I am running
each of these simulations in parallel
on 4 processors each. These simulations are supposed to be running for few
weeks. I noticed that some of
them died without finishing. At the end of the screen output file, I got the
following error message :
FATAL ERROR: Input/output error

Reason: FATAL ERROR: Input/output error

I am trying to understand the source of this error. I am sure that this is
not disk space issue. Can someone please help?
Thanks,
Santanu
