By working together we are able to:
  • resolve issues using better solutions;
  • provide better guidance to vendor partners;
  • improve our own capabilities through sharing knowledge;
  • collaborate to develop capabilities that we would not typically be able to do as individual institutions.

Welcome to SPXXL

SPXXL is a user group for sites which have large installations of IBM or Lenovo equipment. The focus of the SPXXL group is on large-scale scientific/technical computing using IBM or Lenovo hardware. Some of the areas we cover are: Applications, Code Development Tools, Communications, Networking, Parallel I/O, Resource Management, System Administration, and Training. We address topics across a wide range of issues that are important to sustained petascale scientific/technical computing on scaleable parallel machines.

The SPXXL is a self-organized and self-supporting group. Members and affiliates are expected to participate actively in the SPXXL meetings and activities and to cover their own costs for participating. SPXXL meetings are open only to members and affiliates of the SPXXL. SPXXL member institutions must have an appropriate non-disclosure agreement in place with IBM and Lenovo, since at times both vendors disclose and discusses information of a confidential nature with the group. Beginning in 2015 the winter workshop will be focused on Lenovo and their partners and the summer workshop will be focused on IBM and their partners.
