apeNEXT is the latest in the APE collaboration's series of parallel computers for computationally intensive calculations such as quantum chromo dynamics on the lattice. The authors describe the computer architectural choices that have been shaped by almost two decades of collaboration activity.
We present the apeNEXT project which is currently developing a massively parallel computer with a multi-TFlops performance. Like previous APE machines, the new supercomputer is completely custom designed and is specifically optimized for simulating the theory of strong interactions, quantum chromodynamics (QCD). We assess the performance for key application… (More)
