Thanks, this is actually for an academic setting, so a good match. I like the "as much ram as you can get" recommendation, and will probably aim for ~512GB which is a cost-effective maximum. The thought of splitting it into multiple machines has occurred to me, but I'm discouraged by anything that creates distributed problems. There is MPI, but it's cumbersome and performance depends highly on the network (I guess I'll have 10G). Batch management such as slurm works, but also has quite some overhead. Some things are near impossible to distribute, i.e. some algorithms with large matrices. That's why a single e.g. 64 core machine seems more attractive. But I'll take to heart all the recommendations for rack-mount - seems this is a way to prevent a lot of headaches.
