Some experiments in multitasking on an ELXSI system 6400

摘要

In the next six years, Sandia National Laboratories plans to acquire several of the most powerful supercomputers available at that particular time. We anticipate that these machines will have multitasking capabilities. To ensure that the Department of Energy programmatic goals will be met, it is essential that these machines be used efficiently. For this purpose, the Applied Mathematics Division and the Parallel Processing Division at Sandia have underway research programs to investigate the interaction between algorithms, the software environment, and advanced computer architecture for numerical-analysis applications in both mathematical-software libraries and large production codes. This report presents some preliminary results of running a code for solving two-point boundary-value problems in a multitasking environment on the ELXSI 6400.
