At the same time, Field Programmable Gate Arrays (FPGAs) become popular for data-intensive applications, because they promise customized hardware accelerators and achieve high-performance with low power consumption. However, taking advantage of parallel accesses to the local memories of FPGAs remains difficult, as it currently requires application re-engineering. A solution to this challenge is PolyMem, an easy-to-use parallel memory. In this work, we investigate the implementation, integration, and performance of PolyMem…

These experiments possible due to the development of High-Level Languages (HLLs) for FPGAs, which permit non-experts in hardware design languages (HDLs) to program reconfigurable hardware for general purpose computing. However, some of the expert knowledge remains difficult to integrate in HLLs, eventually leading to performance loss for HLL-based applications. One example of such a missing feature is the efficient exploitation of the local memories on FPGAs. A solution to address this challenge…

However, several major challenges remain for migrating existing software to heterogeneous reconfigurable architectures. The EXTRA project aims to develop an integrated environment for developing and programming reconfigurable architectures. The EXTRA platform enables the joint optimization of architecture, tools, and reconfiguration technology, and targets the future High Performance Computing hardware nodes. In this paper, we present four innovative EXTRA technologies: (1) a hardware-software co-design framework; (2) a parallel…
