OpenBLAS is an optimized BLAS library based on GotoBLAS2 1.13 BSD version.
Hi, I'm trying to cross-compile OpenBLAS for Raspbian for ARMV7. The reason for ARMV7 that I use a another 3rd party lib currently only precompiled for ARMV7. For cross-compiling I'm...
I've created a version of the direct sgemm code for AVX2 (it's shared with the AVX512 code with very limited ifdefs, so can compile from the same source). Question is...
When I perform calculations of the type C = (transpose(A))*B I noticed that with openBLAS I don't gain any speedup when I call cblas_dgemm with the right flags to indicate...
Hi everybody, I am using standard lapack routines to diagonalize moderately large matrices with openBLAS. The box is a xeon with 6 cores and hyperthreading. At runtime execution starts with...
When I originally refactored memory.c to reduce locking, I made the (incorrect) assumption that all threads were managed by OpenBLAS. The recent Issues we've seen (#1735) show that really, any...
This is useful, for example, for targets where glibc has deadlock issues with its built-in TLS implementation, as described in #1720.
This is more a comment about an undocumented feature in case other users encounter a similar problem. I have an implementation of the OpenMP runtime that supports multiple copies of...
Small vector scenario. 26.7 seconds for OpenBLAS in Julia: ``` blas_set_num_threads(CPU_CORES) const trans = 'N' const a = ones((201, 150)) const x = ones(150) @time for k=1:1000000; s = BLAS.gemv(trans,...
The program called openblas_set_num_threads(4) before calling dgemm function. Meanwhile, I use top command to monitor CPU usage, I found only one core is running. Otherwise, I call openblas_set_num_threads(1), the time...
