Q. What is task identifier?
Each and every PVM task is uniquely recognized by an integer known as task identifier (TID) assigned by local pvmd. Messages are received from and sent to tids. PVM includes various routines which return TID values so that user application can recognize other tasks in system. PVM supports grouping of tasks too. A task may belong to more than one group as well as one task from one group can communicate with the task in other groups. To use any of group functions a program should be linked with libgpvm3.a.
