Hardware: 1U Dell C1100 poweredge server, 2 and64 hex core processors, 72Gb
RAM.
Installed Ubuntu 14.04 from a USB, created using Rufus from the .iso download
from the ubuntu website
Installed using sudo apt-get: gfortran, dos2unix, build-essential,
liblapack-dev, libblas-dev, mpich2.
Worked Great. ALl my MPI codes in C.C++, fortran passed the test.
However, on powering down and re-powering up, the GUI hangs up at the
Ubuntu screen with several dots, just before the log-in screen. The
machine is not available.
Repeated the process using wget from mpich.org to set up mpich in
another directory. Same problem.
On my hardware, mpich2 causes the 14.04 GUI to hang up.
This is really a problem, because I had to go back to 12.04 to use
mpich2.
