ScicomP

The IBM HPC Systems Scientific Computing User Group (ScicomP) was a non-profit user-led group for scientific and technical users of IBM high-performance computing (HPC) systems. It was part of the SPXXL organization. It held yearly meetings with presentations to allow users share expertise and collaborate on the development of efficient and scalable scientific applications. Though not affiliated with the IBM Corporation, the group's meetings provide an opportunity to give feedback to IBM that would influence the design of future systems.

In 2014, IBM's x86-based server business was transferred to Lenovo, and SPXXL dropped the vendor requirement, opening up membership to all HPC vendors. Active vendors included IBM, Lenovo, Intel, and Mellanox as of 2016. As of 2016, Lenovo still engaged with the user group. It later became HPCXXL.

History
ScicomP was formed in October 1999 when 285 researchers and engineers met at IBM's Advanced Computing Technology Center (ACTC) at IBM Research in Yorktown Heights, NY. The meeting was a user-oriented and planned 3-day workshop to share information on scientific computing techniques for the users of IBM SP supercomputers. The meeting was created on the recommendations of the attendees of the IBM SP Scientific Applications Development and Optimization Workshop held in March 1999 at the San Diego Supercomputer Center. The objective of that meeting was to help computational scientists and engineers develop applications that achieve maximum performance and scalability on the IBM SP systems.

ScicomP held annual and semi-annual meetings that bring together scientific domain experts, computational scientists, systems engineers, and IBM technical specialists. The domain encompassed all IBM HPC Systems, including Power, Blue Gene, Cell, hybrid (e.g. the Los Alamos RoadRunner system), and blade architectures. The meetings alternated between supercomputing sites in North America and Europe.
