Abstract : During this period, we continued to develop the run time system for our prototype enhanced MPI tools. The primary focus was on development of a more complete implementation of the error checking facility for standard MPI send and receive operations, including the ability to handle MPI derived data types. This effort conforms to the approach laid out in our proposal for the core project; it addresses objectives e.4. 1, e.4.2, e.4.3, and e.4.5 in our work plan. In addition to the technical work, we took part in the following activities in relation to the work in this project: 1. We submitted a proposal to Lincoln Laboratory under which Scientific Computing Associates, Inc. will investigate the use of networks of workstations for the MPI version of Lincoln Laboratory's signal processing library. We have received a purchase order and anticipate beginning this effort in February, 1998. While the work is not directly related to this SBIR project (since none of the technology from this project will be used), we do plan to examine the signal processing library as part of our assessment of "real" MPI codes. 2. We submitted a request to Darpa for funding of the options associated with this SB IR project. According to the contract, the options are available for funding as of May 15, 1998, although we anticipate that they may be delayed due to funds availability.
