Non-volatile main memory (NVRAM) enables data persistence in memory. However, the existence of transient CPU caches in modern computer architectures brings a serious performance issue. In particular, cache lines have to be flushed frequently to guarantee consistent persistent program states. Hence, persistence and performance cannot be easily obtained simultaneously. In this paper, we optimize data...
To migrate complex sequential code to multicore, profiling is often used on sequential executions to find opportunities for parallelization. In non-scientific code, the potential parallelism often resides in while-loops rather than for-loops. The do-all model used in the past by many studies cannot detect this type of parallelism. A new, task-based model has been used by a number of recent studies...
We present and review several successful applications using graphic processing unit to accelerate the processing of biomedical optics data including image processing, Monte Carlo simulation, image reconstruction and statistics analysis. It is shown that using GPU can obtain significant performance enhancement comparing with that based on CPU calculation.
