Q. Programming with parallel virtual machine?
The general method for writing a program with PVM is like this:
A user writes one or more sequential programs in C++, C or FORTRAN comprising embedded PVM function/subroutine calls. Every program corresponds to a task making up application. These programs are compiled for every architecture in host pool and resulting object files are placed at a location accessible from machines in host pool. To execute an application a user characteristically begins one copy of one task (normally the 'master' or 'initiating' task) by hand from a machine within the host pool. This procedure then initializes other PVM tasks ultimately resulting in a group of active tasks which then compute locally as well as exchange messages with one another to solve problem.
