Scientific Computing Associates Inc. (SCAI), a provider of parallel and distributed computing products, has developed the open source Sleigh package for executing R functions and applications in parallel. R is a powerful statistical modeling language, but it does not scale well for many compute-intensive analyses. Sleigh was developed to address this limitation.
Sleigh automatically distributes and load-balances R function evaluations across multiple processors in an SMP or cluster, accelerating the execution of R applications. According to SCAI officials, R users can quickly learn how to use Sleigh to take advantage of multiprocessors and achieve significant performance gains.
Because of the increasing popularity of the R statistical scripting language, SCAI now offers commercial support services to R users, including general R support, development of R applications, and design of high-performance R systems. "We are pleased to be able to provide commercial support to R users and to bring to market new programming tools. These services will enable our users to create high-performance applications easily in their customary environments," said Martin Schultz, Founder of SCAI.
SCAI has also announced the availability of NetWorkSpaces. NetWorkSpaces is an open source software package that makes it easy to use multi-core workstations, SMPs, and clusters from within scripting languages such as Matlab, Python, and R. NetWorkSpaces looks and feels like a conventional workspace in the base scripting language. NetWorkSpaces is designed to increase user productivity in implementing and maintaining distributed applications.
"NetWorkSpaces with Sleigh brings high productivity coordination to high productivity computing environments. This combination offers users a simple way to improve performance without leaving the development environment of their choice," said Martin Schultz, Founder of SCAI. "By extending the familiar notion of a workspace, these facilities become easily accessible to almost all programmers."
