Re: Instructions for Installing BLAS and LAPACK library on Octave 5.2.0

[Ilaya Bharathi]

Hi Nicholas,

Thanks for your email.

Is it an openblas library which enables the multithreading is inbuilt with octave ?  

If so, please clarify which dll file(librefblas.dll or libopenblas.dll ) needs to be pasted where. If this is not the case, let me know what to do for the multithreading to work.

finally, after implementing the multithreading feature. how to check it whether it's implemented or not ? 

Many thanks

The openblas library is included with your octave installation and configured for use (assuming you used the installation exe program rather than the zip file). 

I think I remember seeing a BLAS selection option the last time I ran the installer. For zip package users, the readme.html has the following statement:

"During the installation a default BLAS library was selected. The installer contains two BLAS implementations, the NetLib reference BLAS and OpenBLAS.

The choice of library may be changed after installation by copying either librefblas.dll or libopenblas.dll to the file libblas.dll in the bin folder of the Octave installation."
