Introduction

In PVM, all the tasks are identified by an integer supplied by the local daemon: the tid
All the PVM routines are written in C
C++ applications can linked to the PVM library
Fortran application can call these routines through a Fortran interface (translates arguments: reference ® value, takes into account naming convention to call C from Fortran...)
For all functions, a negative value is returned in case of errors
PVM functions begins with pvm_ in C and with pvmf in Fortran
