[Symphony] SYMPHONY Installation with PVM

Hi David,

Goodness, sorry for dropping this---things got very busy.

So, just to check, are you really wanting to use SYMPHONY in a distributed
parallel mode? What is your reason for trying to configure with --with-pvm?
The CoinAll release 1.7.4 include a version of SYMPHONY for which I think
PVM support is a bit broken. To use SYMPHONY with PVM, you should switch to
the most recent release (5.6.1). You can do this easily with svn by going
into the SYMPHONY subdirectory and doing

svn switch https://projects.coin-or.org/svn/SYMPHONY/releases/5.6.1/SYMPHONY

If you just want to solve in parallel on a multi-core machine, this will
happen by default with 5.6.1 using OpenMP. You do not need any configure
options. OpenMP support is automatically enabled.

This is a different problem. It is trying to find the PVM library, which
should be in PVM_ROOT/lib/$PVM_ARCH, where PVM_ARCH is the architecture of
the machine you are on. For me, it is LINUX64. Check to make sure there is
such a directory and a library there. If not, perhaps you forgot to
install? I can't remember, but it is possible, you also have to set the
PVM_ARCH environment variable appropriately as well.

Cheers,

Ted
