PM-PVM: A Portable Multithreaded PVM

PM-PVM is a portable implementation of PVM designed to work on SMP architectures supporting multithreading. PM-PVM portability is achieved through the implementation of the PVM functionality on top of a reduced set of parallel programming primitives. Within PM-PVM, PVM tasks are mapped onto threads and the message passing functions are implemented using shared memory. Three implementation apppr...

PVM-SCI: A PVM Implementation for Heterogeneous SCI-Clusters

| We present PVM-SCI, an implementation of the PVM 3.4 message passing standard for workstation clusters with scalable coherent interface (SCI). PVM-SCI provides two complementary communication schemes: the usual UDP/IP protocol for messages sent via PVM daemons, and a fast communication protocol that has been implemented directly on top of SCI for messages sent with the PvmRouteDirect directiv...

The police challenged the car, but, according to the account in the Rand...
