On programming parallel computers
ACM SIGPLAN Notices, 1975In this paper, I will make some general observations about how computers should be programmed, and how programs should be compiled. I will restrict my attention to programming computers to solve numerical analysis problems, although most of my remarks can be applied to other problem areas as well.

Computing dominators in parallel
Information Processing Letters, 1987Abstract We present a fast parallel algorithm for computing the dominators of a directed acyclic graph. The model of computation used in a parallel random access machine that allows simultaneous reads but prohibits simultaneous writes into the same memory location.

Parallel computers and parallel computing in scientific simulations
2008Users are recommended to know more about the computer architectures and to benchmark the machines before falling in love with a particular machine, unless he/she is willing to die for that love. Even the users' participation in the designing phase of the machine is encouraged, in order to make the end product practical in their applications, otherwise ...

A Short Introduction to Parallel Computers and Parallel Computing
1993This chapter provides a short elementary introduction to parallel computers and parallel computing, and is a prerequisite for a good understanding of the following chapters. We present some architectural multiprocessor characteristics with the emphasis on distributed memory multicomputers.

I shall try to elaborate in a few examples, the desideratum of having machines which perform simultaneously and independently on many channels simple arithmetic and logical operations. I want to discuss briefly the advantages of such a system compared to the now prevailing computers which do their work in series. I shall content myself, in this chapter,

Parallel Computing Enables Whole-Trip Train Dynamics Optimizations
, 2016Due to the high computing demand of whole-trip train dynamics simulations and the iterative nature of optimizations, whole-trip train dynamics optimizations using sequential computing schemes are practically impossible. This paper reports advancements in

Using Straggler Replication to Reduce Latency in Large-scale Parallel Computing
PERV, 2015In cloud computing jobs consisting of many tasks run in parallel, the tasks on the slowest machines (straggling tasks) become the bottleneck in the completion of the job.

Massively parallel computers: why not parallel computers for the masses?
[Proceedings 1992] The Fourth Symposium on the Frontiers of Massively Parallel Computation, 2003The developments in high-performance computers towards achieving the goal of a teraflops supercomputer that would operate at a peak speed of 10/sup 12/ floating-point operations per second are reviewed. The net result of the quest for parallelism as chronicled by the Gordon Bell Prize is that applications evolved 115% per year and will most likely ...

Parallel Computing in Global Optimization
2005Global optimization problems arise in a wide range of real-world problems. They include applications in operations research, engineering, biological sciences, and computer science. The effective use of parallel machines in global optimization is a very promising area of research since, due to inherent difficulty of problems it studies, only instances ...
