3次元FPGAアレイHPCシステムVocaliseの性能評価

摘要

We have developed a 10cm square card with a three-dimensional I/O that installed a 4 million system gate scale FPGA and have already confirmed its basic operation. We are building a High Performance Computing (HPC) system constituted by connecting the card in the shape of a three-dimensional array. We called that HPC system as a Virtual Object by Configurable Array of Little Scalable Engine (Vocalise). In this report, the communication circuit of this HPC system is described. In addition, we implement a Poisson's equation arithmetic circuit on the system, and report its operation performance and power consumption.%400万システムゲ一ト規模のFPGAを搭載し3次元方向に外部入出力端子を有す10cm角のカードを作成し，その基本動作は確認済みである.このカードを3次元アレイ状に接続したHigh Performance Computing (HPC)システムVirtual Object by Configurable Array of Little Scalable Engine (Vocalise)を構築している.本報告では,このHPCシステムの通信回路について述べる.また，実際に本システム上にポアソン方程式演算回路を実装し，システム全体の演算性能と消費電力を測定した結果についても報告する.
