3 SAN DIEGO SUPERCOMPUTER CENTER at the UNIVERSITY OF CALIFORNIA; SAN DIEGO Trestles - Configuring for productivity for modest-scale and gateway users Allocation Plans Target users that need <=1K cores Plan to allocate ~70% of the theoretically available SUs Cap allocation per project at 1.5M SUs/year (~2.5% of annual total). Allow new users to request up to 50,000 SUs in startup allocations, and front-load the SUs offered during the first few allocations cycles. Configure the job queues and resource schedulers for lower expansion factors and generally faster turnaround. Challenge will be to maintain fast turnaround as utilization goes up Services Shared nodes Long-running queue Advance reservations On-demand queue ~20 nodes set aside in on-demand queue. Users can run here at 25% (TBR) discount. Jobs may be pre-empted (killed) at any time for on-demand users (initial pathfinder is SCEC for realtime earthquake analyses)

5 SAN DIEGO SUPERCOMPUTER CENTER at the UNIVERSITY OF CALIFORNIA; SAN DIEGO Users to date

6 SAN DIEGO SUPERCOMPUTER CENTER at the UNIVERSITY OF CALIFORNIA; SAN DIEGO CIPRES gateway growth

7 SAN DIEGO SUPERCOMPUTER CENTER at the UNIVERSITY OF CALIFORNIA; SAN DIEGO Results from the CIPRES gateway Identify evolutionary relationships by comparing DNA To date, >2000 scientists have run more than 35,000 analyses for 100 completed studies. These studies span a broad spectrum of biological and medical research. The following discoveries were made by scientists using the Gateway over the past year: Hepatitis C virus evolves quickly to defeat the natural human immune response, altering the responsiveness of the infection to interferon therapy. Humans are much more likely to infect apes with malaria than the reverse. Toxic elements in local soils influence the geographical distribution of related plants. Red rice, a major crop weed in the US, did not arise from domestic rice stock. Beetles and flowering plants adapt to each other over time, to the benefit of both species. Viruses can introduce new functions into Bakers’ yeast in the wild. A microbe called Naegleria gruberi, which can live with or without oxygen, provided new insights into the evolutionary transition from oxygen-free to oxygen-breathing life forms.

8 SAN DIEGO SUPERCOMPUTER CENTER at the UNIVERSITY OF CALIFORNIA; SAN DIEGO Recent Dash Results: Flash Application Benchmarks LiDAR Topographical database: Representative query of a 100 GB topographical database Test configuration: Gordon I/O nodes. 1 with 16 SSD’s an 1 with 16 spinning disks. Running single and concurrent instances of DB2 on the node. EM_BFS: Solution of 300M node using flash for out-of-core Test configuration: Gordon I/O nodes. 1 with 16 SSD’s, and 1 with 16 spinning disks. Abaqus: S4B – Cylinder Head Bolt Up. Static analysis that simulates bolting a cylinder head onto an engine block. Test Configuration: Single Dash compute node run comparing local I/O to spinning disk and flash drive. Reverse Time Migration: Acoustic Imaging/Seismic Application Test Configuration: Dash Compute nodes with local SSD and local spinning disk. Protein databank: Repository of 3D structures of molecules Test configuration: Gordon I/O nodes. 1 with 16 SSD’s, and 1 with 16 spinning disks.

9 SAN DIEGO SUPERCOMPUTER CENTER at the UNIVERSITY OF CALIFORNIA; SAN DIEGO Flash Provides 2-4x Improvement in Run Times for LiDAR Query; MR-BFS, and Abaqus

10 SAN DIEGO SUPERCOMPUTER CENTER at the UNIVERSITY OF CALIFORNIA; SAN DIEGO Gordon Schedule (Approximate) Sixteen production-level flash I/O nodes are already in- house for testing Early results for a single I/O node: Random I/O (4K blocks): Read 420K IOPS, Write 165K IOPS Sandy Bridge availability early summer System delivery to SDSC late summer Friendly user late fall Production before end of CY11 First allocation meeting: “Sept” cycle

11 SAN DIEGO SUPERCOMPUTER CENTER at the UNIVERSITY OF CALIFORNIA; SAN DIEGO SDSC’s Broader HPC Environment In addition to TeraGrid systems … SDSC operates: Triton (Appro 256-node cluster + 28 Sun large-memory nodes 256/512 GB) SDSC system supporting staff, industrial partners, & UCSD/UC users Thresher (IBM 256-node cluster) UC-wide system, along with Mako at LBNL, operated for systemwide users as part of a UC-wide Shared Research Computing Services (ShaRCS) pilot for condo computing Data Oasis –Lustre parallel file system Shared by Triton, Trestles (and Gordon) Phase 0 – 140 TB Phase 1 – currently in procurement, ~ 2PB (raw), ~50 GB/s BW Phase 2 – Summer 2012 – expansion for Gordon to 4PB, ~100 GB/s

12 SAN DIEGO SUPERCOMPUTER CENTER at the UNIVERSITY OF CALIFORNIA; SAN DIEGO Recent EOT Activity Planning Spring vSMP training workshop Track 2D Early User Symposium (in conjunction with TG-11) SDSC Summer Institute on HPC and Data-Intensive Discovery in Environmental and Ecological Sciences, featuring TG resources and TG Science Gateways Presenting a poster and hosting the TG booth at the Tapia Conference in April; will promote TG-11, internship and job opportunities, and encourage new TG/XD users. Computational Research Experience for Undergraduates (CREU) program this spring, and REHS (Research Experiences for High School Students) in summer 2011 Last year's program was very successful. Applications this year are very strong. TeacherTECH and StudentTECH programs are continuing, 2-3 per week. Portal development continues for Campus Champions and MSI-CIEC communities. Partnership with the San Diego County chapter of the Computer Science Teachers Association will host their second joint meeting in May (first in February). Engaging with state-wide effort to bring CS education to all high schools
