摘要

某些工程问题引起线性方程组AX=B，其中A是一个大而密的矩阵。ProSolver-DES是专为此类问题设计的Intel iPSC/860系统的核外密集求解器。最近，英特尔推出了另一款平板式求解器，它可以实现全列旋转。该求解器的性能略低于ProSolver-DES，但在128个节点的系统上仍然可以获得超过4 gflop的性能。Paragon-XP/S是英特尔的下一代并行超级计算机。它在所有设计尺寸上都提供了比iPSC/860性能的巨大飞跃。同时，编程模型完全支持iPSC/860的消息传递模型，为iPSC/860编写的程序可以在Paragon系统上不加修改地运行。密集求解器将在Paragon上可用，并且运行速度将大大提高。

Out of core dense solvers on Intel parallel supercomputers

Certain engineering problems give rise to systems of linear equations AX=B, where A is a large, dense matrix. ProSolver-DES is an out-of-core dense solver for the Intel iPSC/860 system which was specifically designed for such problems. Recently Intel introduced an alternate slab-style solver which does full column pivoting. The performance of this solver is slightly less than that of ProSolver-DES, but still obtains well over 4 Gflops on a 128-node system. The Paragon-XP/S is Intel's next-generation parallel supercomputer. It provides a quantum leap in performance over the iPSC/860 in all design dimensions. At the same time, the programming model fully supports the message passing model of the iPSC/860, and programs written for the iPSC/860 will run unmodified on the Paragon system. The dense solvers will be available on Paragon and will run significantly faster.<>
