On the Performance of Multidimensional Array Representations in Programming Languages Based on Virtual Execution Machines

Abstract. This paper evaluates the performance of virtual execution machines (VM) of the CLI and JVM standards for the common approaches to represent multidimensional arrays in high performance computing applications. In particular, it shows which representation is the best for each virtual machine implementation, showing that the choices may be surprisingly contradictory, even with respect to ...

Usability of Programming Languages

Programming languages form the interface between programmers (the users) and the computation that they desire the computer to execute. Although studies exist for some aspects of programming language design (such as conditionals), other aspects have received little or no human factors evaluations. Designers thus have little they can rely on if they want to make new languages highly usable, and u...
