LAM/MPIer's:
As a followup: we have rolled back our version of LAM to 7.0.6, and this version works fine -- no problems with redirected stdin. This is an acceptable solution for us, but
it also suggests a bug in 7.1.1.

As being the reporter of that bug, I thought of the similarities when
I saw your message, but I wanted to see more details before jumping
in. As the discussion revealed, I had no problems with LAM 7.0.3 while
all the CVS versions (that later became 7.1.x) gave the same strange
behaviour; however, something like 2-3 months after that discussion
took place I did try again the CVS for an unrelated reason and I was
able to do stdin redirection; that was for sure before 7.1 was
released, so I concluded that the problem was found and fixed.
Due to the fact that a massive recompilation of MPI applications would
be required for a LAM version change, I stayed with 7.0.3 until now
and I can't therefore provide any data about 7.1.

I was also using FC1 at that time, both when I originally reported the
problem and later when the stdin redirection worked. I switched to
TaoLinux1 (RHEL3 clone) in the mean time as FC1 is no longer
supported, but I have not tested any LAM 7.1 since I made the switch.
I realize that I'm not bringing any new data, but I thought that a
summary might help...
