2. 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

3. 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

4. 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.
