The task is minimized by using the PVM (Parallel Virtual Machine) code from Oak Ridge Labs to provide the distributed utility. It is relatively easy to enhance CLIPS (C Language Integrated Production System) to support multiple expert systems running in a distributed environment with heterogeneous machines. Using PVM to host CLIPS in distributed environments The ' pvm_spawn' and ' pvm_parent' function calls are not replaced, but a programmer can use 'mpirun' and knowledge of the ranks of parent and child tasks with supplied macroinstructions to enable execution of codes that use ' pvm_spawn' and ' pvm_parent.' Because PVM Wrapper is written to run with MPI- 1.2, some PVM functions are not permitted and must be replaced - a task that requires some programming expertise. These characteristics make it difficult to obtain equivalent functionality via a single MPI 'send' call. In many cases, these calls are not contiguous and one set of calls may even exist over multiple subroutines.

Codes written when PVM was popular often feature patterns of calls. Since about 1996, MPI has been the de facto standard. PVM and MPI are the two most common software libraries used for applications that involve passing of messages among parallel computers. At this point, the extension of all files, including the PVM files should be displayed after the file name.PVM Wrapper is a software library that makes it possible for code that utilizes the Parallel Virtual Machine ( PVM) software library to run using the message-passing interface (MPI) software library, without needing to rewrite the entire code. On the 'View' tab, you will find 'Hide extensions for known file types' – you should mark this option and confirm by pressing 'OK'. Then, go to the 'Folder Options' and open the 'View' tab. Just go to 'Control Panel' and select 'Appearance and Personalization'. However, you can successfully change this in the settings. In the standard Windows settings, a computer user cannot see the PVM file extension. My computer does not show file extensions, what should I do? If the computer still has problems with the files, use the services of an expert who will diagnose a specific cause. Solving these problems should allow the free opening and working with the PVM files. incomplete installation of the program that supports a PVM file? accidental deletion of the PVM file from the Windows registry insufficient computer hardware resources corruption of a PVM file, that you want to open

an incorrect link to the PVM file in the registry entries

The reason for the fact that the PVM file can’t be opened and used can also be: Sometimes even the software, installed on your computer, that supports the PVM files does not solve the problem. However, problems with the PVM files can also have a different background.
