While removing software bugs consumes vast amounts of human time, hardware support for debugging in modern computers remains rudimentary. Fortunately, we show that mechanisms for ...
Garbage collection can be a performance bottleneck in large distributed, multi-threaded applications. Applications may produce millions of objects during their lifetimes and may i...
With the shrinking of transistors continuing to follow Moore's Law and the non-scalability of conventional outof-order processors, multi-core systems are becoming the design ...
In chip multiprocessors (CMPs), data accesslatency dependson the memory hierarchy organization, the on-chip interconnect (NoC), and the running workload. Reducing data access late...
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...
