LPVM: a step towards multithread PVM
نویسندگان
چکیده
LPVM (Lightweight-process PVM) system is an experimental PVM version which supports the use of lightweight-process or threads as the basic unit of parallelism. It was designed to study potential performance improvements and implementation issues required by multithreaded message-passing systems. The current version of LPVM was implemented on SMPs using the native threads and is designed to be thread-safe. Initial test results on SUN SMP are compared to standard PVM.

LPVM: Low-Power Variation-Mitigant Adder Architecture Using Carry Expedition
Addition is one of the most crucial operation in microprocessors which must be performed within a predefined deadline (critical path). Variation is a phenomenon which negatively affects the performance of this operation. This paper proposes a new Low-Power Variation-Mitigant (LPVM) adder design using intrinsic behavior of addition operation. The LPVM approach drastically decrease the probabilit...
متن کاملIntegrating Zipcode and PVM: Towards a Higher-Level Message-Passing Environment
This paper describes the architecture and implementation of an integrated message-passing environment consisting of Zipcode and PVM. Zipcode is a highlevel message-passing system for multicomputers and homogeneous networks of computers. PVM is a relatively low-level message-passing system designed for multicomputers and heterogeneous networks of computers. Although PVM provides a workable and e...
متن کاملParallel implementation of a unified approach to image focus and defocus analysis on the Parallel Virtual Machine
A uniied approach to image focus and defocus analysis (UFDA) was proposed recently for three-dimensional shape and focused image recovery of objects. One version of this approach which yields very accurate results is highly computationally intensive. In this paper we present a parallel implementation of this version of UFDA on the Parallel Virtual Machine (PVM). One of the most computationally ...
متن کاملTowards Reconfigurable Cache Memory for a Multithreaded Processor
Recently reconfigurable devices such as FPGA have improved performance (gate speed and the number of gates) and reconfiguration time. Today , a reconfigurable device can integrate a large-scale processor and complex hard-wired logic. System designers found that they need a high-performance processor for their reconfigurable device based systems. To improve processor performance , a multithreade...
متن کاملGenetic Adventures in Parallel: Towards a Good Island Model under PVM
Genetic algorithms (GAs) have proved to be a very useful and flexible way to solve difficult combinatoric problems. Arriving at high quality solution however often involves a very large number of evaluations and consequentially is quite computationally demanding. Evaluating GAs in parallel is thus desirable, but specialty parallel computers are not available to many who might benefit from paral...
