Dgemm algorithm
WebSuppose we implement DGEMM on Cypress GPU, i.e., S = 8. It has the theoretical peak speed of F = 544 Gflop/s. If we assume that b is small enough to put a block of C on each thread processor’s register file, we need memory bandwidth of BDGEMM = 0.544(Tflop/s) × 8/b = 4.352/b TB/s. With b = 1 (non-blocking algorithm), we need massive bandwidth WebJan 1, 2012 · Open access. In this paper we will present a detailed study on tuning double-precision matrix-matrix multiplication (DGEMM) on the Intel Xeon E5-2680 CPU. We …

Webmance of DGEMM in Fermi using this algorithm is shown in Figure 3, along with the DGEMM performance from CUBLAS 3.1. Note that the theoretical peak of the Fermi, in this case a C2050, is 515 GFlop/s in double precision (448 cores # 1:15 GHz # 1 instruction per cycle). The ker-nel described achieves up to 58% of that peak.
