MS 7

Radical-Pilot MS-7

Driving Use Cases

• EnsembleMD-TK
• Troy v2.0

Main Features

• (1) MPI support (multi-node) MAY
• (2) Cray support JUNE
• (3) scalability/performance toward use cases JULY
• (4) ability to share staged data between CUs JULY

MPI and Cray support will be provided in separate agents. That will (initially) exclude the use case of inter-node MPI on Cray.

Responsibilities

• detailed requirements for EnMDTK: OW (April)
• detailed requirements for Troy: AM (April)
• MPI: MS (April/May), OW (April / May)
• Cray: AT (April / May), OW (May/June)
• data staging/sharing: MS (June/July)
• performance, delivering towards EnMDTK, Troy: AM (April-July), Ole (June, July)
• target release date: end of July (Ole is away parts of May/June)
