ATLAS is an extremely popular linear algebra library.
When you install ATLAS from source, it tries to automatically tune a number of parameters to give you the fastest code. Does it make sense to do this tuning when installing ATLAS on a cloud server like AWS or GCE? I know that these services often provide shared VMs, and presumably the performance of these VMs can change based on what other VMs on the same physical hardware are doing.
Is there a way to get ATLAS installed and tuned correctly when installing on a cloud service?
