Question 307
|
Which of the following statements is incorrect for Parallel Virtual Machine (PVM) ?
|
The PVM communication model provides asynchronous blocking send, asynchronous blocking receive, and non-blocking receive function.
|
|
|
Message buffers are allocated dynamically.
|
|
|
The PVM communication model assumes that any task can send a message to any other PVM task and that there is no limit to the size or number of such messages.
|
|
|
In PVM model, the message order is not preserved.

Question 307 Explanation:
PVM (Parallel Virtual Machine) is a software package that permits a heterogeneous collection of Unix and/or Windows computers hooked together by a network to be used as a single large parallel computer. Thus large computational problems can be solved more cost effectively by using the aggregate power and memory of many computers. The software is very portable. The source, which is available free thru netlib, has been compiled on everything from laptops to CRAYs.
→ PVM enables users to exploit their existing computer hardware to solve much larger problems at minimal additional cost. Hundreds of sites around the world are using PVM to solve important scientific, industrial, and medical problems in addition to PVM’s use as an educational tool to teach parallel programming. With tens of thousands of users, PVM has become the de facto standard for distributed computing world-wide.
