Graph500 電力測定中 その３

以下の計算サーバ１と２ですが、大きな GPU を外して小さな GPU を取り替えました。



以下のように性能(median_TEPS)はかなり向上しています。もちろん電力性能も向上です。
◯前回
計算サーバ１：5.529 GTEPS
計算サーバ２：2.615 GTEPS
◯今回
計算サーバ１：6.540 GTEPS
計算サーバ２：5.363 GTEPS

◯計算サーバ１
SandyBridge-EP マシン：Intel Xeon E5-2690 2.90GHz : 8 Core 20M L3 cache x 2
Memory DDR 3 1600 ECC REG 256GB (16GB x 16)
OS : CentOS 6.3

◯計算サーバ２
SandyBridge-EP マシン：Intel Xeon E5-2650 2.00GHz : 8 Core 20M L3 cache x 2
Memory DDR 3 1600 ECC REG 256GB (16GB x 16)
OS : CentOS 6.3
