INSPIRE: The insieme parallel intermediate representation

摘要

Programming standards like OpenMP, OpenCL and MPI are frequently considered programming languages for developing parallel applications for their respective kind of architecture. Nevertheless, compilers treat them like ordinary APIs utilized by an otherwise sequential host language. Their parallel control flow remains hidden within opaque runtime library calls which are embedded within a sequential intermediate representation lacking the concepts of parallelism. Consequently, the tuning and coordination of parallelism is clearly beyond the scope of conventional optimizing compilers and hence left to the programmer or the runtime system.
