First Delivery. . .

Last year’s Usage Approaching 1 Million cpu hours/week

Resources & Expertise • Storage of large data sets (2100 TB) • High Performance Storage (Panasas) • High bandwidth transfers (9 gbps, ~50 TB/day) • 20 gbps between sites, 10 gbps to Internet 2 • High Performance Computing: ~10, 000 cores • Grid computing and High Throughput Computing

Usage Options • Shared Access • Free • Opportunistic • Storage limited • Shell or Grid • Priority Access deployment

Usage Options • Priority Access • Fee assessed • Reserved queue • Expandable Storage • Shell or Grid deployment

Computational and Data. Sharing Core • Will meet computational demands with a combination of Priority Access, Shared, and Grid resources • Storage will include a similar mixture, but likely consist of more dedicated resources • Often a trade-off between Hardware, Personnel and Software • Commercial Software saves Personnel time • Dedicated Hardware requires less development (grid protocols)

Computational and Data. Sharing Core • Resource organization at HCC • Per research group -- free to all NU faculty and staff • Associate quotas, fairshare or reserved portions of machines with these groups • /home/swanson/acaprez/. . . • accounting is straightforward

Computational and Data. Sharing Core • Start now - facilities and staff already in place • It’s free - albeit shared • Complaints currently encouraged (!) • Iterations required
