Q. Define PVM library routines?
In this segment we will give a short description of the routines in PVM 3 user library. Each PVM program must comprise the PVM header file 'pvm3.h' (in a C program) or 'fpvm3.h' (in a FORTRAN program).
In PVM 3, all PVM tasks are recognized by an integer supplied by the local pvmd. In the subsequent descriptions this task identifier is termed as TID. Now we are introducing a number of generally used functions in PVM programming (as in C. For FORTRAN we exploit prefix pvmf against pvm in C).
