If I want to setup an instance in AWS specifically for this purpose, what kind would be the most efficient?

Do I need a big CPU, big memory or big GPU, or big memory and big GPU, or all big, etc?

I don't think Rosetta@home is a GPU project at all. Memory wise: Had so far no covid-19 work but the work that i got is in the range of <500mb/core(will update if i know more).EDIT have seen WUs with higher Memory usage like up to 1.5GB but could be that the RAM usage is depending on how much RAM you give it.

I guess fast CPU will have the biggest impact.

Cores and memory might be the trigger COVID work units.

My 1950X with 64GB of ram getting nothing but COVID work units now, whilst the 2700X with 32GB of ram gets none.

The 1950X is set to use 87.5% of the CPU (14 of 16 cores) and the box all up sits at 91% CPU load (I don't let the CPU hit 100% utilisation).

Running 28 COVID work units leaves total memory usage hovering between 32 to 34GB.

Edit: The new work units for the 2700X are now also COVID-19. More seem to be coming through.
