I've got PVM3.3 running on a SGI Onyx and would like to figure out
if there is any way to specify how many tasks to spawn on the
multiprocessor (within a given PVM machine) other than with the
spawn -(count) 
command at the PVM console.  Ideally, there is a means either within
the hostfile or on the command line...

Alternatively, I would like to figure out how to get the spawn command
within the PVM console to work at all!  Given an application (foobar),
I have no problem starting it by:

% pvm
> add freya
1 sucessful
                    HOST     DTID
                   freya    80000
> conf
2 hosts, 1 data format
                    HOST     DTID     ARCH   SPEED
                   frigg    40000     HPPA    1000
                   freya    80000     HPPA    1000
> quit
pvmd still running.
% foobar

OR:

% pvmd hostfile &
% foobar

However,
% pvmd hostfile &
% pvm
pvmd already running.
pvm> spawn foobar
1 successful
t80001
pvm> quit
...never seems to run foobar (a pvm> ps shows nothing running!)

Thanks for any help!
