How to create your own plugin

Plugin--need a kernel (computational or packing) not supported by BLIS

Compile this for all the different architectures blis with right opt flags.

To get existing examples:

./configure-plugin <plugin-name>

Gives a sample plugin that can be build into a library and use.

Directories

• config
  : every configuration our installed version of BLIS knows about. Each directory has those files from BLIS that define that configuration. What makefile flags to use. A place *.c we could register optimized kernels for that architecture. A *.h file to Define things like default Mr and NR block size we want to use.

• ref_kernels : Reference kernels

• kernels:

in Header, we have to have a kernel ID that the application uses to find the kernels that we have written. Prototypes of kernels.

Must register kernels before you can use the kernels.
