Hello, A change in allocation has been requested: Requester: yyu (Yiqi Yu) Project: SHARP_ARC Title: Multi-physics Simulation of SFR Core Radial Expansion with SHARP Description: As the SHARP modeling and simulation toolkit is maturing, the focus is on customer-oriented applications and further validation exercises. This allocation will help with those applications, for performing small to moderate scale simulations and for scaling up to ALCF. The SHARP toolkit is regularly compiled on Blues using Intel or GNU compilers. The components of SHARP—the Nek5000 computational fluid dynamics code and the PROTEUS neutron transport code—have already been demonstrated to scale well not only on Blues but on Blue Gene/P. This project will be used by 4-5 analysts in the NE and MCS Divisions. Current: undetermined amount Justification: FY17 efforts for SHARP are highly focused on solving challenge problems for customers and code validation. FY16 efforts were focused on code development, as there was a major release, and so computational requirements were lower than usual. If the project is successful, we anticipate that FY17 and beyond will be highly resource intensive. The components of SHARP—the Nek5000 computational fluid dynamics code and the PROTEUS neutron transport code—have already been demonstrated to scale well not only on Fusion but on Blue Gene/P. Nek5000 has demonstrated > 80% parallel efficiency on BG/P (strong scaling) out to P=131,072 processors, using only 7300 points/processor at the largest scale. PROTEUS has demonstrated greater than 90% strong space-angle scaling at the 100,000 processer level and was nominated for the Gordon Bell Prize for its parallel performance. Requested: 1000000 A specific reason has been given: Used up all the time for now. have urgent job to finish before March This needs to be approved and the final allocation amount decided upon. Thank You, The LCRC Accounts System
