Parallel Matlab: RTExpress on 64-bit SGI Altix with SCSL and MPT

Abstract

By late 2004 RTExpress(Trademark), a compiler and runtime environment that provides the capability for MATLAB (Registered) script files to be directly compiled and then executed on parallel high performance computers (HPC), will be released for the SGI platform, including the new Altix Itanium systems. 1 This new version of RTExpress(TradeMark) will take advantage of the SGI hardware and software package. specifically 64- bit operation, the SGI MPT (Message Passing Toolkit), the SGI SCSL (Scientific Computing Software Library), and is the first version of RTExpress(TradeMark) to utilize the advantages of a global shared-memory system. This paper presents the first test results using this new release. Improvement in corner-turn timing is anticipated due to the SGI NUMAlink interconnect fabric. as compared to other interconnect technology common in Linux clusters, such as Ethernet. Up to an order of magnitude improvement in corner turn performance, and overall 2D FFT performance is expected.
