10 Where did SCD come from? “Blue Book” 1959 “Blue Book” Link “There are four compelling reasons for establishing a National Institute for Atmospheric Research” 2. The requirement for facilities and technological assistance beyond those that can properly be made available at individual universities

11 SCD Mission Enable the best atmospheric & related research, no matter where the investigator is located through the provision of high performance computing technologies and related services

14 Computing Services for Research Operates two distinct computational facilities. –Climate simulations –University community Governance of these SCD resources in the hands of the users - two external allocation committees. Computing leverages a common infrastructure for access, networking, data storage & analysis, research data sets, and support services including software development, and consulting.

15 Climate Simulation Laboratory (CSL) The CSL is a national, multi-agency, special-use, computing facility for climate system modeling for the U.S. Global Change Research Program (USGCRP). – Priority projects that require very large amounts of computer time. CSL resources are available to U.S. individual researchers with a preference for research teams regardless of sponsorship. An inter-agency panel selects the projects that use the CSL.

16 Community Facility The Community Facility is used primarily by university-based NSF grantees and NCAR Scientists. – Community resources are allocated evenly between NCAR and the university community. NCAR resources are allocated by the NCAR Director to the various NCAR divisions. University resources are allocated by the SCD Advisory Panel. Open to areas of atmospheric and related sciences.

31 ARCS RFP Overview BEST VALUE PROCUREMENT –Technical evaluation –Delivery schedule –Production disruption –Allocation ready state –Infrastructure –Maintenance –Cost impact – i.e. existing equipment –Past performance of bidders –Business proposal review –Other considerations - invitation to partner

32 ARCS Procurement Production-level –Availability, robust batch capacity, operational sustainability and support –Integrated software engineering and development environment High performance execution of existing applications Additionally – environment conducive to development of next-generation models

33 Workload profile context Jobs using > 32 nodes –0.4 % of workload –Average 44 nodes or 176 pes Jobs using < 32 nodes –99.6 % of workload –Average 6 nodes or 24 pes

34 ARCS – The Goal A production-level, high-performance computing system providing for both capability and capacity computing A stable and upwardly compatible system architecture, user environment, and software engineering & development environments Initial equipment: At least double current capacity at NCAR Long Term: Achieve 1 TFLOPs sustained by 2005

35 ARCS – The Process SCD began technical requirements draft Feb 2000 RFP process (including scientific reps from NCAR divisions, UCAR Contracts, & external review panel) formally began Mar 2000; RFP released Nov 2000 Offeror proposal reviews, BAFOs, & Supplemental proposals Jan-May 2001 Technical Evaluations, Performance projections, Risk Assessment, etc. Feb-Jun 2001 SCD Recommendation for Negotiations 21 Jun; NCAR/ UCAR acceptance of recommendation 25 Jun Negotiations Jul; tech. Ts&Cs completed 14 Aug Contract submitted to the NSF 01 Oct NSF Approval 5 Oct … Joint Press Release week SC01

36 ARCS RFP Technical Attributes Hardware (processors, nodes, memory, disk, interconnect, network, HIPPI) Software (OS, user environment, filesystems, batch subsystem) System admin., resource mgmt., user limits, accounting, network/HIPPI, security Documentation & training System maintenance & support services Facilities (power, cooling, space)

37 Major Requirements Critical Resource ratios: –Disk6 Bytes/peak-FLOP: 64+ MB/sec single-stream & 2+ GB/sec bandwidth - sustainable –Memory0.4 Bytes/peak-FLOP “Full-featured” product set (cluster-aware compilers, debuggers, performance tools, administrative tools, monitoring) Hardware & Software stability Hardware & Software vendor support & responsiveness (on-site, call center, development organization, escalation procedures) Resource allocation (processor(s), node(s), memory, disk; user limits & disk quotas) Batch Subsystem and NCAR job scheduler (BPS)

38 ARCS – Benchmarks (1) Kernels (Hammond Harkness, Loft) Single Processor (COPY, IA, XPOSE, SHAL, RADABS, ELEFUNT, STREAMC) Multi-processor shared memory (PSTREAM) Message-Passing Performance (XPAIR, BISECT, XGLOB, COMMS[1,2,3], STRIDED[1,2], SYNCH, ALLGATHER) Parallel Shared Memory Applications –CCM (T42 30-days & T170 1-day) – CGD, Rosinski –WRF Prototype (b_wave 5- days) - MMM, Michalakes more >
