Hi LAM Developers and users,
I am running LAM MPI for use with the
"Global_Arrays" programs written at the Pacific North
National Lab.
http://www.emsl.pnl.gov/docs/global/ga.html
It has been working great across a cluster of several
SMP's, but I've been having a problem with jobs on 1
SMP. I get an error that says "Too Many Open Files."
I talked to an AIX developer, and he points out that
if you set your file descriptor limit to its maximum,
the OS reports it as unlimited, but in reality it is
limited to 10,000 per process.
Is it possible to approach that limit while using
LAM-MPI? Are there still any known issues with
removing old fd's?
Here is my laminfo output:
LAM/MPI: 7.0.4

I can't think of what else I should include to help
describe the problem. I have been unable to replicate
the error with dbx. Also, AIX is no POSIX compliant,
but is Unix98 compliant (I doubt this will help much.)
I have been running with rsh boot and the tcp RPI.
Many Thanks,
Andy
