HPCXXL is a user group for sites which have large installations of IBM or Lenovo equipment. The focus of the HPCXXL 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 multi-petascale scientific/technical computing on scaleable parallel machines.

The HPCXXL is a self-organized and self-supporting group. Members and affiliates are expected to participate actively in the HPCXXL meetings and activities and to cover their own costs for participating. HPCXXL meetings are open only to members and affiliates of the HPCXXL. HPCXXL 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 2018 the spring workshop will be co-located with the HPC Advisory Council Switzerland in Lugano without a vendor dedicated focus. The summer/autum workshop will be traditionally focused on IBM and their partners.
