PVM

PVM (Parallel Virtual Machine) is a portable message-passing programming system, designed to link separate host machines to form a ``virtual machine'' which is a single, manageable computing resource. The virtual machine can be composed of hosts of varying types, in physically remote locations. PVM applications can be composed of any number of separate processes, or components, written in a mixture of C, C++ and Fortran. The system is portable to a wide variety of architectures, including workstations, multiprocessors, supercomputers and PCs.

        Release Notes: New architectures supported: Darwin/MacOS X, Cygwin, and Beoscyld. There are many bugfixes and a couple of new features. One new feature is the concept of a "Virtual Machine ID". You can now set the PVM_VMID environment variable to an arbitrary string (or use the "id=" option in a host file), and this will distinguish multiple virtual machines all running on the same set of hosts under the same userid.

            Release Notes: This release fixes the setting PVMDPATH in the hostfile, the "readline" compile error in Linux, and a compile error on HP-UX. New features in PVM 3.4.x include communication contexts, message handlers, persistent messages, and interoperablity between NT and Unix clusters. It also includes a new faster port to shared-memory multiprocessors, and PVM 3.4 works much better with Linux than PVM 3.3.11.
