As computational applications become common for graphics processing units, new hardware designs must be developed to meet the unique needs of these workloads. Performance simulation is an important step in appraising how well a candidate design will serve these needs, but unfortunately, computational GPU programs are so large that simulating them in detail is prohibitively slow. This work addresses...
As multicore processors are deployed in mainstream computing, the need for software tools to help parallelize programs is increasing dramatically. Data-dependence profiling is an important program analysis technique to exploit parallelism in serial programs. More specifically, manual, semiautomatic, or automatic parallelization can use the outcomes of data-dependence profiling to guide where and how...
To exploit the full performance potential of multicore desktops, the authors propose an approach that combines cache optimization, parallelization, simdization, and autotuning in a single framework.
As multicore processors are deployed in mainstream computing, the need for software tools to help parallelize programs is increasing dramatically. Data-dependence profiling is an important technique to exploit parallelism in programs. More specifically, manual or automatic parallelization can use the outcomes of data-dependence profiling to guide where to parallelize in a program. However, state-of-the-art...
Software instrumentation provides the means to collect information on and efficiently analyze parallel programs. Using Pin, developers can build tools to detect and examine dynamic behavior including data races, memory system behavior, and parallelizable loops. Pin is a software system that performs runtime binary instrumentation of Linux and Microsoft Windows applications. Pin's aim is to provide...
Heterogeneous multiprocessors are increasingly important in the multi-core era due to their potential for high performance and energy efficiency. In order for software to fully realize this potential, the step that maps computations to processing elements must be as automated as possible. However, the state-of-the-art approach is to rely on the programmer to specify this mapping manually and statically...
