DOUBLE PRECISION for dgemm. COMPLEX for cgemm, scgemm. DOUBLE COMPLEX for zgemm, dzgemm. Specifies the scalar beta. When beta is equal to zero, then c need not be set on input. c. REAL for sgemm. DOUBLE PRECISION for dgemm. COMPLEX for cgemm, scgemm. DOUBLE COMPLEX for zgemm, dzgemm. Array, size ldc by n.
DGEMM is a pronoun of general double-precision matrix-matrix multiplication in BLAS [4]. It is a performance critical kernel in numerical computations including LU factorization, which is a benchmark for rank-ing supercomputers in the world. We take DGEMM as an example to illustrate our insight on Fermi’s performance op- DGEMM performance subject to (a) problem size N and (b) number of active. cores for N =4 0, 000. (Color figure online) of course. Note that the av ailable saturated memory bandwidth is independent.

One of these is argued to be inherently superior over the others. (In [Gunnels et al. 2001; Gunnels et al.
The micro-benchmarks that we tested are STREAM [18] which performs four vector operations on long vectors, and DGEMM (double-precision general matrix-matrix multiplication) from Intel's Math
Single-precision or double-precision GEMM (SGEMM/DGEMM). dgemm to compute the product of the matrices. The arrays are used to store these matrices: The one-dimensional arrays in the exercises store the matrices by placing the elements of each column in successive cells of the arrays. This project contains a simple benchmark of the single-node DGEMM kernel from Intel's MKL library. The Makefile is configured to produce four different executables from the single source file. The executables differ only in the method used to allocate the three arrays used in the DGEMM call. The benchmark currently consists of 7 tests (with the modes of operation indicated for each): HPL (High Performance LINPACK) – measures performance of a solver for a dense system of linear equations (global).

Here, the function calling dgemm takes 500 more times that numpy matrix product. I suspect it is because of the marshalling in a minor way, and majoritarily because of the "c binding".

Each test consisted of 100 runs with the first run being discarded. each benchmark was repeated 5000 times; the benchmarking process was pinned to the first core on the system; FLOPS were computed using 5000×(2×M×N×K)/Δt where N, M, and K are the relevant dimensions of the matrices and Δt is the wall clock time; DGEMM Benchmark Showing 1-12 of 12 messages. DGEMM Benchmark: Emily M: 7/31/12 8:11 AM: Hi all, The HPC Challenge benchmark consists of basically 7 tests: HPL - the Linpack TPP benchmark which measures the floating point rate of execution for solving a linear system of equations. DGEMM - measures the floating point rate of execution of double precision real matrix-matrix multiplication. Categories: benchmark, open-source, APEX The Crossroads/N9 DGEMM benchmark is a simple, multi-threaded, dense-matrix multiply benchmark.
If we apply our adaptive Winograd algorithm on top of MKL and Goto's and we normalize the performance using the formula 2N^3/nanoseconds, we achieve up to 6.5GFLOPS. Notice Figure 7 (b) shows measured DGEMM performance with respect to the number of active cores. When the frequency is fixed (in this case at 1.6 GHz, which is the frequency the processor guarantees to attain when running AVX-512 enabled code on all its cores), DGEMM performance scales all but perfectly with the number of active cores (black line).
