Re: [Users] Einstein Toolkit and modern AMD supercomputer

Hello all,

• Avoid buffer zones by using an improved time interpolation scheme

(I've seen papers, I don't know about 3d code)

Eloisa, Ian, I and Erik worked on this for a bit quite a while ago. The results can be found in branch ianhinder/rkprol:

git clone -b ianhinder/rkprol https://bitbucket.org/cactuscode/cactusnumerical.git

note that this is actually a change to MoL not not so much Carpet. This implementation should work, but is not optimized and most likely still has (way) too much communication. Based on two presentations at the ET meeting in Stockholm:
