Montreal, Canada and Belfast, UK (14 November 2005) -- OptimaNumerics and eXludus Technologies, leaders in high performance technical and scientific computing software and data-driven grid management software, today announced a long-term agreement, effective immediately, to co-market eXludus' RepliCator software product and OptimaNumerics Libraries. The two complementary products enhance different aspects of workload performance.

eXludus Technologies founder and CEO, Benoit Marchand said, "We are pleased to announce our new joint marketing relationship with OptimaNumerics. This allows us to offer the advantages of highly scalable data movement with RepliCator in conjunction with maximal computational performance from OptimaNumerics Libraries, to address both aspects of highly challenging customer workloads. Customers can now leverage both best-of-breed technologies to assure efficiency, enhanced productivity and boost ROI."

OptimaNumerics founder and CEO, Dr Kenneth Tan said, "The extreme performance of OptimaNumerics Libraries coupled with RepliCator will enable end users to perform computations at even higher levels of efficiency, with RepliCator reducing the computational jobs' idle times."

eXludus' data transfer management technology addresses data-intensive cluster and grid production workloads in research, life sciences, oil and gas, manufacturing and finance. RepliCator broadcasts data to all nodes in a cluster or grid, exploiting the improved performance and capacity of local storage. It especially benefits throughput-oriented workloads with moderate to high data rate. eXludus has measured aggregate data rate speedups of up to 11-fold versus on-demand data serving, and near-linear scaling to 256 processors. Recent tests on the rice and human genomes with NCBI-BLAST have resulted in 1.8 to 2.7 times greater throughput at 64 cpus than achieved through traditional on-demand data serving. RepliCator and its accompanying Meta Language Processor Module also support asynchronous data transfer to allow efficient pre-staging of data to cluster nodes and Edge grids.

OptimaNumerics Libraries, with linear algebra, parallel linear algebra and parallel random number generators modules, provide high performance versions of LAPACK, ScaLAPACK, PETSc, SuperLU, PLFG and SPRNG libraries. OptimaNumerics has benchmarked computational solution performance improvement of up to 13 times on SGI Altix supercomputers and up to 6 times on Sun Opteron clusters. OptimaNumerics' innovative technologies have consistently delivered superior performance and portability across a wide range of platforms: the Intel Xeon, Xeon EM64T and ItaniumII processor families, IBM PowerPC970, IBM POWER5, AMD Opteron, and Sun UltraSPARC architectures.
