What users need in parallel tool support: survey results and analysis

Considerable effort and expense have been devoted to developing tools that support parallel programming. Recent evidence has show that users do not find the current generation of tools useful far their program development needs, but offers no guidance on how that problem might be addressed. This paper reports the results of a survey applied to a significant cross-section of the parallel user community (448 participants). The responses establish a number of general patterns in program development and tool use among scientists, engineers, and computer scientists. Our analysis suggests several likely directions for future tool development efforts
