What is HPC? High Performance Computing (HPC) Scales across many nodes, needs a low latency network High Throughput Computing (HTC) Scale out, each node independent, same code different data Advanced Computing Bigger than your laptop Includes HPC, HTC, cloud, storage, vizualization, etc

Advanced Computing at UH ITS We use a condo model for campus computing Base system – FREE to all UH students, staff and affiliates PI’s can purchase nodes or time for priority access Condo model Common to many US research universities Alternative: Departmental and lab scale resources Also common and co-existing here at UH

Condo-nomics Sharing economy: most like Air B&B Increase efficiency by increasing asset utilization Expand access to goods Provide income to owners Enabled by low transaction costs Air B&B enabled by the web Condo model enabled by job schedulers, ex. SLURM The owner shared nodes are like an Air B&B, but one where you stay for free. Then the bears come home and quickly kick you to the curb. The income to owners is free scratch space, free sysadmin , free procurement, free hosting. Kill queue users that have check pointing or short enough jobs end up making progress.
