Abstract
A status report is given on recent work on the vectorization and parallelization of the ITPACKV 2C [4] software. This package has been modified for improved performance on vector supercomputers resulting in a new version called ITPACKV 2D [10] that includes wavefront techniques. The main reason for these changes was to obtain improved vector performance of several methods that did not vectorize in the previous version. Results are also presented on initial efforts at modifying this package to produce a parallel ITPACKV suitable for execution on shared-memory parallel computers with relatively small numbers of processors.
