In preparation to the work I intend to submit for go1.13, we would certainly need new POWER9 builders to test the new instructions.

Do you have any preferences on where to set these up? Is OSU still fine?

Thanks!

@ceseo Who are you asking?

From the point of view of the Go project, I think anywhere reliable is fine.

@ianlancetaylor thanks! I'd like the opinion of any of the maintainers before start setting them up.

So, I guess I'll set them up at OSU, since our current builders POWER8 are there too.

@bradfitz cool, thanks!

What sizing did you use for the current POWER8 builders? (disk/CPUs/memory)
