Open Source Software and Solutions for R –
A Powerful Statistical Modeling Language

  • R ServicesScientific Computing Associates, Inc. (SCAI) has been a proven leader in the field of high performance software for over 25 years. Recently the increasing adoption of R, a statistical scripting language, has led SCAI to create a “practice” in the area of R,
    R application development, and high-performance R systems.

    R is a powerful statisical modeling language, but does not scale well for many compute-intensive analyses. SCAI has built an open source R package called Sleigh™ to address these limitations. SCAI supports the development of high performance R applications. We also enable R programs to run faster using our parallel tools when appropriate.


    SCAI has utilized its expertise in HPC to develop the open-source Sleigh package for executing R functions and applications in parallel. Sleigh is R-compatible software.

    Sleigh automatically distributes and load-balances R function evaluations across multiple cores, processors, or nodes in a cluster or on a network to speed the execution of R applications. R users quickly and easily can learn how to use Sleigh to take advantage of multiprocessors, with incredible performance gains in almost no time (see chart below).
