I'm running (fortran) pvm on a sun 4.1.3 network using a master/slaves
topology. The slaves are large though, maybe 20 meg. What I'm seeing
is that if too many slaves try to startup on one machine, it seems to
require too much memory and just hangs. There are various fixes I
could do, such as restrict the number of spawnings, etc, but is there
some way to at least make the failure more benign? This problem also
seems to brake the debugger, since there you have to run on one
machine. Purify is able to run though.
