- SX-3/44 at Dorval Accepted
-
- On December 17 1992 the SX-3/44 installed at the Dorval
- supercomputer center completed the last of the formal acceptance
- requirements and was switched into operational mode. The machine is
- now the main production system used for the support of weather
- forecasting in Canada.
-
- The SX-3/44 is a 22 GFLOP vector supercomputer produced by NEC
- Corporation of Japan. The Canadian system, originally installed in
- October of 1991, consists of 4 vector processors, each with a 5.5
- GFLOP nominal performance, 1 GByte of main memory, and 4 GBytes of
- extended memory. Connected to the machine is a 200 GByte disk farm of
- high performance parallel disks.
-
- Over the year since the initial installation of the machine
- employees of Environment Canada, the machine's major client, have
- converted a large base of software from the proprietary Cray Operating
- System to run under the UNIX environment of the SX-3/44. At the
- completion of the conversion efforts, the major application of the
- weather forecasting system, a finite element based weather prediction
- code, runs in 1/3 of the elapsed time on a single processor of the
- SX-3/44 as it did on 4 processors of an XMP 4/16 EA machine. For this
- application this shows an almost 12 times improvement in performance
- over the previous production machine.
-
- With the conversion effort complete, Environment Canada employees
- are now shifting their efforts to projects that will take advantage of
- the increased performance of the SX-3/44 to improve the quality and
- accuracy of products.
-
- Hardware and software reliability of the SX-3/44 have proven to
- be excellent. The Dorval machine exceeds 99% up time across the total
- system.
