Baseline data¶

Current instance types for wb2 cypress tests at https://ci.arvados.org/view/Developer/job/developer-tests-workbench2/ are: n2-standard-4
Last runs took around 25 minutes to succeed.

• Run times are approximates, can vary a bit from run to run.

For the t2d-standard-8 case, I tested normal and spot instances. Spot instances worked ok, I think it's worth trying them.
If we want to save time while not spending more money, we should use the t2d-standard-4 instances.

The t2d types assign 1 whole core per vCPU, while the n2d types assign 1 core thread per vCPU, so multithreaded apps benefit from t2d instances.

I've also tried to run the pipeline using c2 and c3 instance types, but they failed to even start, I haven't found any information about their architecture but maybe they're not x86 compatible?

I left Jenkins configured so that it uses t2d-standard-8 Spot instances.
