Next, in an Ope 09/01/2021 If the executable you are using does not use Intel's OpenMP implementation, then you might want to try the Intel MKL DGEMM benchmark instead. There is a download link attached to the article at: There is a download link attached to the article at: • Fermi DGEMM Optimization / Performance • Linpack Results •Conclusions . LINPACK Benchmark The LINPACK benchmark is very popular in the HPC space, because it is used as a performance measure for ranking supercomputers in the TOP500 list. The most widely used implementation is the HPL software package from the Innovative Computing Laboratory at the University of Tennessee: It solves a random … DGEMM Benchmark Code While peak performance numbers look great on data sheets, most designers also want to know what the sustained performance is with a familiar benchmark. DGEMM is a matr ix-matrix multiplication added to an existing value. The product AB (matrix A multiplied by matrix B) is given by for each pair i and j with and . The DGEMM A single C2050 gives about 550 GFLOP/s peak, or about 2200 GFLOP/s for 4 peak for double precision, and DGEMM is considerably lower than peak), so I would guess that you timing is wrong in the streams case (probably something that was synchronous in the default stream case is now asynchronous).

In those graphs we report performance of our implementation as well as vendor implementations (Intel’s MKL (8.1.1) and IBM’s ESSL (4.2.0) libraries) and ATLAS [Whaley and Dongarra 1998] (3.7.11) on the Intel Pentium4 Prescott … The Crossroads/N9 DGEMM benchmark is a simple, multi-threaded, dense-matrix multiply benchmark. The code is designed to measure the sustained, floating-point computational rate of a single node. The code is designed to measure the sustained, floating-point computational rate of a single node. 07/01/2019 High Performance DGEMM on GPU (NVIDIA/ATI) Abstract Dense matrix operations are important problems in scientific and engineering computing applications. There have been a lot of works on developing high performance libraries for dense matrix operations. Basic Linear Algebra Subprograms (BLAS) is a de facto application programming interface standard for publishing libraries to perform … accumulated DGEMM performance of all contributing processing elements. – The accumulated Max. Perf.

Our optimizations include software pipelining, use of vector memory operations, and instruction scheduling. Our best CUDA algorithm achieves comparable performance with the latest CUBLAS library. We further improve upon this with … const char* dgemm_desc = "Simple blocked dgemm."; #if !defined(BLOCK_SIZE) #define BLOCK_SIZE 41 #endif #define min(a,b) (((a)<(b))?(a):(b)) /* This routine performs a dgemm operation * C := C + A * B * where A, B, and C are lda-by-lda matrices stored in column-major format. * On exit, A and B maintain their input values. */ void square_dgemm (int lda, double* A, double* B, double* C) { /* For each block-row of … This example shows how to evaluate the performance of a compute cluster with the HPC Challenge Benchmark. The benchmark consists of several tests that measure different memory access patterns.

When I launch a single DGEMM where the matrices are large (m=n=k=15,000), the performance improves as I increase the number of threads used, which is expected. For reference, I get about 467 GFLOPs/sec using 24 cores.

additional 8 registers are temporarily used to store the next block of matrices A/B. The requirement of more registers leads to register spilling to local memory.

2001; Gunnels et al. 2005] three of these six kernels were identiﬁed.) Careful consideration of all these observations underlie the implementation of the dgemm Basic Linear Algebra Subprograms (BLAS) routine that is DGEMM The DGEMM benchmark measures the sustained floating-point rate of a single node. IOR IOR is used for testing performance of parallel file systems using various interfaces and access patterns. Mdtest A metadata benchmark that performs open/stat/close operations on files and directories. Jun 20, 2016 · For DGEMM, the attained performance for N=5000 is 1.85 TFLOP/s in double precision (see Appendix), which is 70% of the theoretical peak performance of our processor. Therefore, the usage of Intel MKL remains crucial for extracting the best performance out of Intel architecture.
