Hello !

I'm using PVM to have a dynamical host configuration while
running. At runtime there are slave hosts added and deleted.
Now I wanted to use PGPVM to display graphically the load
of the processors involved.

The problem is that I'm deleting hosts while the program
is running and PGPVM doesn't recognize this - and I don't know
how to tell PGPVM that a host is no longer valid.
A deleted host is directly replaced by another host.

Do I have to make a new pgftids() call to tell PGPVM about the
new configuration - and do I have to send the pgftids to
all processors involved or only to the new one ???

My problem is at the moment, that the pgfmcast() call at the
end with the end sign 
and the pgfexit() call fails. I think they don't know 

about the missing host.

I'm programming in FORTRAN.

I would be very very glad if anyone could tell me what the
problem could be.

Many thanks in advance.

Sabine
