GAUSS 9.0 Math & Statistical System for Multi-threading

New threading functions let you define independent sections of your program that will run at the same time.

Aptech Systems, Inc. (Black Diamond, WA) is shipping GAUSS version 9.0, the latest version of its GAUSS Mathematical and Statistical System that includes functions for multi-threading both new and existing programs.

This illustration shows one thread set with four threads. Each thread processes at the same time as the other threads. Your program waits at the ThreadJoin command for all threads to fi nish. When the threads have completed, your program continues, making use of the work the threads have done.

In the example here, this block of code could potentially run nearly four times faster on a quad core machine because the threads are running simultaneously. Internal testing by Aptech has found speed increases of up to 330 percent using four threads on a four-core system. GAUSS 9.0 allows the creation of an unlimited number of threads, allowing users to take full advantage of multi-core and multi-processor machines. Thread creation is limited only by operating system resources.

Threads can be created anywhere in a program, including inside procedures and keywords. These threads share the same workspace and can access all of the same symbols, procedures and keywords.

GAUSS 9.0 includes additional array support; more mathematical functions will handle arrays seamlessly; and it is available for Windows (32-bit), Linux (32-bit and 64-bit), and Sun SPARC (64-bit).
