Q. What are Dynamic Process Groups?
To create and manage dynamic groups a separate library libgpvm3.a should be linked with the user programs which make use of any of group functions. Group management work is handled by a group server which is automatically started when first group function is invoked. Any PVM task may leave or join any group dynamically at any time without having to inform another task in affected groups. Tasks can transmit messages to groups of which they aren't members.
