Executing applications in parallel can produce significant performance gains, yet the time and expertise needed for the low-level details of parallelism is often prohibitive. Additionally, many applications rely heavily on domain-specific libraries, while it is not practical to write an optimizing compiler each time a domain-specific library is developed. In order to obtain high performance parallelism from a high-level, domain-specific scripting language, we are developing a parallel Matlab compiler, called the Matlab D compiler, using a telescoping languages framework to generate Fortran with MPI from Matlab scripts.
