| - | So the question was raised what does our usage look like between CPU and GPU? I have no idea what the appropriate metrics would be but lets start with comparing the hardware deployed. | + | So the question was raised what does our usage look like between CPU and GPU devices?

| + | * Data is period June 1 to June 25, 2018 (job information data ages out) | ||
| + | * Maybe build monthly script if this turns out to be usable info | ||
| + | * That period covers 600 hours of time | ||
| + | * Assume 99% utilization of cpu core or gpu device | ||
| + | * Available time is measured per cpu core but by gpu device | ||
| + | * There is no good/bad metric | ||
| + | * Never collated such data before | ||
| + | * The GPU usage is based on detecting gpu reservations (gpu= flag) | ||
