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...
Asymmetric multicore processors (AMP) consist of cores exposing the same instruction-set architecture (ISA) but varying in size, frequency, power consumption and performance. AMPs...
Recently, mashups have emerged as an important class of Web 2.0 collaborative applications. Mashups can be conceived as personalized Web services which aggregate and manipulate dat...
