IU n Major partnership between IU and IBM n HPSS, IBM RS/6000 SP, IBM SSA Disk n Initially 1 TB disk, 17 TB tape n Innovative Web interface using DFS and HPSS n Ongoing research partnership between IU and IBM

Computational IU n 47P IBM RS/6000 SP. IU’s largest supercomputer, currently 357th on Top500 List. Primary parallel and research computing resource for IU. n 64P SGI Origin2000. Currently 385th on Top500 List n 64P Compaq PC Cluster (32 2-processor Compaq Proliants) n Significant (and growing) presence of Sun servers for interactive computing

IU ’ s Parallel PC cluster n 32 Compaq Proliant, dual Pentium II n Key feature: Evenhanded approach to OS issues. Key questions: Which is better under what circumstances? n Combination of computer science research, (production) scientific calculation, and artistic applications n One of three installations in US using NT and Linux interchangeably on same hardware n NSF MRI Proposal

IU ’ s SGI Origin 2000 n Purchased via NSF Infrastructure grant n Used primarily by an interdisciplinary team of 12 research labs, in fields ranging from Astronomy to Theatre n Used for some of the largest Radiance jobs ever rendered

IU ’ s IBM RS/6000 SP n Primary computational resource for IU researchers, ranging from beginning grad students to computer science researchers n Robustness and architecture of IBM RS/6000 SP provide excellent services to this great breadth of users (SPSS to MPI) n The RS/6000 SP has the Globus toolkit installed, and is a key component of our distributed computing efforts

IU - Key areas of intellectual leadership n HPC software technologies, esp. distributed HPC n Cosmology & astrophysics n Computational Chemistry n High Energy Physics (Quantum Chromodynamics) n HPC best practices, practical uses of distributed computing n Virtual Reality, Photorealistic rendering, virtual shopping n Broad, multidisciplinary use of HPC technology

Brief history of IU/IBM Collaborations n IBM 3090 in support of quantum chemistry algorithm development (Davidson) - MELD n Two SUR grants in support of VARIATIONS n SUR grant for IBM SP2, for development of HPC++ and middleware for geographically distributed computing (Gannon) - HPC++, PARDIS n SUR grant for IBM SP Upgrade for Component Technology development (Bramley) - CAT n Major partnership announcement May 25th!

Notable HPC Awards/Presentations n HPC Challenge - SC95 - Best Integration of Heterogeneous Applications. “Galaxies Collide on the I- WAY: An Example of Wide-Area Collaborative Supercomputing.” Team lead by Dennis Gannon n HPC Challenge - SC98 - Best Industrial Collaboration. “"Industrial Mold Filling Simulation Using an Internationally Distributed Software Component Architecture.” Team lead by Randall Bramley n CASCON ‘98: Component architecture toolkit (Bramley); Evolutionary biology and distributed computing (Stewart et al.)

Component Architecture Toolkit n Component architectures revolutionized desktop computing, but have so far had less impact on HPC n IU is a leader in development of component technologies for HPC, and a member of the DOE 2000 CCA group n Significant results already building upon the LSA and implementing the CAT for IBM RS/6000 SPs n The CAT is ideal as a vehicle for exploitation of high performance computing and networking resources n As hardware converges upon clusters of SMP systems, do we really expect many scientists using HPC systems to master MPI, OpenMP, and how to mix them optimally?

i GRID n An international collaborative demonstration project to prototype next-generation network-based research and education tools shown at SC98. Partnership between EVL and IU. n Twenty applications demonstrated projects of international collaborative research involving sites located in ten countries around the world. n Demonstrations from the fields of metacomputing (computational fluid dynamics, cosmology and biology); shared virtual workspaces; digital video; tele- manufacturing; instrument control

The problem with grids... n How do you create more than a transient demonstration project? n IU is leading multinational effort to create a “free (cycle) trade zone” in support of bioinformatics and evolutionary biology computations with NUS and ACSys n IU is leading efforts to create a persistent computational grid within the CIC n IU is a key partner in the NCSA Alliance

QCD n Prof. Gottlieb is an internationally recognized leader in Lattice Gauge Theory and Quantum Chromodynamics n Gottlieb’s QCD code has been run on a variety of HPC hardware, including PC clusters (Gottlieb Lab, UITS, NCSA, UNM), NCSA Origin2000s n Initial tests with scaling of QCD codes on Power3 nodes yielded disappointing scalability. Investigating and correcting this would be interesting and useful

Evolutionary Biology n International collaboration based primarily on IBM RS/6000 SPs at IU and National University of Singapore n Leverages commonalities in HPC hardware, code, and research interests

IU ’ s Massive Data Storage Project n Based on IBM hardware, HPSS n Now: 1 TB spinning disk, 17 TB tape n Soon: 2 TB spinning disk, 57 TB tape n Serves both academic and business needs of IU. VTS used to automate and improve tape handling.

IU ’ s Massive Data Storage Project n Web-based front end to Massive Data Store - permits easy access to data without installation of additional clients via JavaScript, DFS, and HPSS n Web interface designed to handle both large files and small files (student use). Key question: how to package and manage large numbers of small files n Data management and access a key area of IU’s HPC research activities

Goals for this visit n Present our accomplishments stemming from our partnership with IBM and previous SUR grants. n Strengthen and deepen research relationships between Indiana University and IBM in areas of mutual interest. n Identify areas of joint interest in deep computing research; set plans for joint HPC research activities in the coming year. n Identify opportunities for collaboration in high performance networking applications and digital libraries.
