Mpich 1.2.1 problems

Hi all,

  I think I've got more problems with mpich on our 16 nodes cluster.

  I'm trying to install mpich 1.2.1 (latest rev) from source. I can
compile it with no apparent problem, but when I try to make and run the
tests under examples/test with "make testing" I get several errors,
particularly I get one recurrent error :

  [mpdcon]: failed to close fd 17

  I have compiled mpich with : 
   
   ./configure --with-arch=LINUX --with-device=ch_p4mpd --with-mpe -opt=-g
   make

  using gcc, f77 and pgf90 (I didn't want to try pgf77 until I was sure I
didn't have any other problem). 

  By the way, cpi under examples/basic works without any flaw with :

   mpd &
   startdaemons 4
   mpirun -np 4 cpi

  Therefore I don't think it's a big issue in p4mpd. 
  Oh, the nodes are all diskless, mounting root via nfs from the
server. Maybe it's a problem of nfs... 

  Any advice would be appreciated.

  Thank you all in advance,


                              Franz Marini
