Dear Professor Fox,

This is Kazuo Minami of RIST, Japan.

I am sorry about the delay of my paper for special issue of "Concurrency

and Computation".
I send my paper in PDF format.


Best Regards,

Kazuo Minami

We have a prospect that Geofem get good parallel performance on various computer
architecture by the research which has been made in GeoFEM team. In this
research, we focus a target to performance with a single processor, and common
data structure / coding manner to make GeoFEM running high performance on
various computer architecture was researched.

<b>Test coding for Solver Part of the structure and the fluid analysis code</b>
Data structure and coding manner was evaluated on scalar/vector/pseudo vector
architecture. A new data structure and a new direct access manner was introduced
in the fluid analysis solver. As a result, 21% performance for peak performance
was obtained on pseudo vector architecture. And We got as good performance
as the pseudo-vector execution performance in scalar execution. 25% performance
for peak performance was obtained on vector architecture.
A new direct access manner was introduced in the structure code solver.
As a result, 27% performance for peak performance was obtained on pseudo vector
architecture. 34% performance for peak performance was obtained on vector
architecture.
<b>Test Code for Matrix Assemble Part of the structure analysis code</b>
Coding of removing dependency was finished and performance was evaluated
on vector/scalar machine. 736.8MFlops was obtained at matrix assembling process
on SX-4. 900.7MFlops was obtained at whole test Code on SX-4, and
2.06GFlops was obtained on VPP5000 (peak : 9.6GFlops). 124MFlops was obtained
at matrix assembling process on Alpha system (Alpha 21164 533MHz).
