High-level vs low-level parallel programming for scientific computing

Summary form only given, as follows. This talk briefly reviews some of the most popular high-level and low-level parallel programming languages used for scientific computing. We will report our experiences of using these languages in our research and compare the performance of several parallel scientific equation solvers implemented in different parallel languages. Major features and comparisons of these languages will be discussed. Some insights into when and where these languages should be used will be provided.
