High-level Parallel Computing language (HPCL) combines the high performance of Clusters and the easy-to-use property of high-level language Octave. A HPCL program will run concurrently in a set of virtual machines (VMs). Therefore, HPCL programs are machine independent. HPCL keeps the elegant of the current high-level languages. It only needs one additional operator @ to transfer data and commands among the VMs. HPCL is also compatible to the conventional high-level language. Any sequential high-level Octave programs can be run properly in HPCL environment without modification. The realization of HPCL is briefly introduced in this report, including the main system components, execution strategy and message transfer protocol.
