Tim Moon 9de52b489a Cleaning up and documenting multi-threaded GEMM code. 2017-10-03 16:32:08 -07:00
Tim Moon 860dcfc703 Use 2D thread distribution for small GEMMs. 
Allows maximum use of available cores if one of M and N is small and the other is large.

Christoph Conrads 77b197bc93 Make: fix installation instructions 
The installation instructions as shown after successfully compiling
OpenBLAS are wrong because this arguments used during compilation have
to be provided to Make again.

Christoph Conrads 9cc6599056 ARM: do not add linker flag `-lm` unconditionally 
On ARM the required math library depends on whether the soft floating
point ABI is used or not but this is already handled in
`Makefile.system`, lines 499-505.

Christoph Conrads da611dd81a ARM: recognize gfortran pre-releases 
Without proper recognition of gfortran versions such as
> GNU Fortran (GCC) 4.9.x 20150123 (prerelease)
OpenBLAS assumes the presence of the G77 compiler. Consequently,
`-lgfortran` is missing from the pkg-config file.

The aforementioned compiler is the gfortran compiler in the Android repo
in a commit tagged as `ndk-r14`, cf. Paul Mustière's gfortran build
instructions for Android at https://github.com/buffer51/android-gfortran
