This paper describes performance of OSCAR multigrain parallelizing compiler on various SMP servers, such as IBM pSeries 690, Sun Fire V880, Sun Ultra 80, NEC TX7/i6010 and SGI Altix 3700. The OSCAR compiler hierarchically exploits the coarse grain task parallelism among loops, subroutines and basic blocks and the near fine grain parallelism among statements inside a basic block in addition to t...

The grain size refinement of AISI 422 martensitic stainless steel in the temperature range of 950-1150 ºC was investigated by hot deformation tests. The deformed specimens were held at deformation temperature with delay times of 5 to 300s after achieving a strain of 0.3. The austenite grains exhibit a considerable growth at temperature higher than 1050˚C, while the grain coarsening is negligibl...

A coarse-grain parallel program typically has one thread (task) per processor, whereas a fine-grain program has one thread for each independent unit of work. Although there are several advantages to fine-grain parallelism, conventional wisdom is that coarse-grain parallelism is more efficient. This paper illustrates the advantages of fine-grain parallelism and presents an efficient implementati...
