In the past years, computing has been moving from the sequential world to the parallel one, from centralized organization to decentralized. This paper presents a short description of a PVM (Parallel Virtual Machine) toolkit, developed and implemented for the Windows operating system. It is intended to provide a graphical interface for PVM administration and process monitoring. The toolkit will ...

In this paper a comparison between two of the most signiicant and common tools for distributed computing, PVM and Linda, is carried out. These tools may be used to program a cluster of workstations as well as several commercial multiprocessors and multicomputers and are based upon two completely diierent computational paradigms: message-passing (PVM) and the shared tuple space (Linda). The pape...

Checkpointing and rollback recovery is a simple technique for fault tolerance. The state of a process is saved on a disk file from which the process can recover on the occurrence of failure. In this paper we describe the implementation of FTOP (Fault Tolerant PVM), a coordinated checkpointing library integrated with PVM. Existing PVM applications require only minor change for incorporating faul...

Version 3.4.3 of PVM had previously been enhanced by the addition of a new architecture, BEOLIN, which allowed a PVM user to abstract a Beowulf class computer with a private network to appear as a single system, visible to the outside world, which could spawn tasks on different internal nodes. This new enhancement to PVM handles the case where each node on the Beowulf system may be composed of ...

This paper describes DynamicPVM, an extension to PVM (Parallel Virtual Machine) 1]. PVM enables users to write parallel applications using message passing primitives and statically places the parallel tasks on a collection of nodes. System schedulers schedule atomic jobs over a predeened number of nodes. DynamicPVM addresses the problem of scheduling parallel tasks over a set of nodes. It there...

In this paper, we describe an object-based distributed shared memory called Adsmith. In an object-based DSM, the shared memory consists of many shared objects , through which the shared memory is accessed. Adsmith is built on top of PVM at the library layer using C++. PVM is used as the communication subsystem because it is a de facto standard and encapsulates many system related details. Sever...

Concurrent and distributed computing, using portable software systems or environments on general purpose networked computing platforms, has recently gained widespread attention. Many such systems have been developed, and several are in production use. This paper describes the evolution of the PVM system, a software infrastructure for concurrent computing in networked environments. PVM has evolv...

The Parallel Virtual Machine (PVM) Package is available now at many sites and can be used to develop truly heterogeneous programs for multiple computer systems. The PVM Package is a software package developed at Oak Ridge National Laboratory and Emory University. It enables a heterogeneous collection of UNIX computers that are linked in a network to function as a single parallel computer. PVM a...

Gene silencing is an important regulatory and defense mechanism in plants. Plant viruses evolved some proteins that suppress cellular RNA interference mechanism. In this work identification of silencing suppressors of potato virus M (PVM) is reported. The cDNA sequences of different PVM open reading frames were cloned into the Gateway-compatible binary T-DNA destination vector pMDC32, harboring...
