我使用英特尔MKL的函数cblas_sgemv进行矩阵-向量乘法,但此函数每次都会给出不同的结果。有时,这可以给出正确的结果(与参考结果相比,L2范数中的误差为1e-6 )。我已经检查了这个函数的输入每次都是相同的,我只是根据this do 浏览26提问于2019-10-05得票数 0 1回答 编译c++时连接openblas和mkl库 、、...

CUDA is actually slower that CPU code. Most of my operations are matrix-vector multiplications, with sizes of the order of hundreds (ie 500x100). In order to see from which size CUBLAS sgemv is faster than CBLAS sgemv, I wrote this small...
I try to force cblas_sgemv_batch_strided to run on ONE thread. I set : mkl_set_num_threads_local( 1 ) or mkl_domain_set_num_threads(1, MKL_DOMAIN_BLAS) or mkl_domain_set_num_threads(1, MKL_DOMAIN_ALL); or both but I can see a lot of tbb thread in all cases I...
