Prior research in software environments focused on three important problems-- tool integration, artifact management, and process guidance. The context for that research, and hence...
Various studies have shown that OS jitter can degrade parallel program performance considerably at large processor counts. Most sources of system jitter fall broadly into 5 catego...
In many scientific applications, significant time is spent tuning codes for a particular highperformance architecture. Tuning approaches range from the relatively nonintrusive (...

Abstract. In order to take full advantage of high-end computing platforms, scientific applications often require modifications to source codes, and to their build systems that ge...
The MPI standard provides tool builders with an efficient profiling interface, PMPI. Although many tools have successfully used this interface, it has three major drawbacks: a n...
