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.

Thanks to the improvements in semiconductor technologies, extreme-scale systems such as teradevices (i.e., composed by 1000 billion of transistors) will enable systems with 1000+ general purpose cores per chip, probably by 2020. Three major challenges have been identified: programmability, manageable architecture design, and reliability. TERAFLUX is a… (More)
In order to minimize code size overhead on VLIW ar-chitectures, compilers for embedded processors have to pay higher attention on code optimization than on compilation time. Thus, the rst demand on compiler for embedded processors consists in spending instruction memory space for optimization only if the associated performance improvement justiies it. In… (More)

This paper presents the implementation of a video decoding application starting from its dataflow and CAL representations. Our objective is to demonstrate the ability of the Open RVC-CAL Compiler (Orcc) to generate code for embedded systems. For the demonstration, the video application will be an MPEG-4 Part2 decoder. The targeted architecture is a… (More)
