Porting of the parallel Fortran preprocessor, Pfortran, to Intel Corporation and IBM Corporation massively parallel processor machines is presented. The machines include the Intel iPSC/SSO, the Caltech Intel DELTA, the Intel Paragon, and the IBM SPl. The UHGROMOS molecular dynamics program, a version of GROMOS ported to parallel machines through the use of Pfortran, was used as a test applicati...

Real-time computing on parallel machines has not received much attention, although many real-time applications can bene t from high performance computing. The RealTime Parallel Benchmark Suite (RTPBS) is designed to help evaluate the suitability of parallel machines for real-time computations. The suite contains application level, kernel level, and low level benchmarks. The purpose of this pape...

No existing parallel architecture (including SIMD machines, MIMD machines, vector processors, machines with a common, globally-addressable memory, machines with private memories) has demonstrated its superiority for all possible applications. That is, given different applications, different parallel machines may deliver the highest absolute performance or the best price-performance. A good solu...

Although several papers have studied no-idle scheduling problems, they all focus on flow shops, assuming one processor at each working stage. But, companies commonly extend to hybrid flow shops by duplicating machines in parallel in stages. This paper considers the problem of scheduling no-idle hybrid flow shops. A mixed integer linear programming model is first developed to mathematically form...

Appropriate scheduling and sequencing of tasks on machines is one of the basic and significant problems that a shop or a factory manager encounters; this is why in recent decades extensive studies have been done on scheduling issues. One type of scheduling problems is just-in-time (JIT) scheduling and in this area, motivated by JIT manufacturing, this study investigates a mathematical model for...
