[GitHub] [incubator-mxnet] Zha0q1 opened a new pull request #19172: Make OpenBLAS use the LAPACKE apis

Zha0q1 opened a new pull request #19172:
URL: https://github.com/apache/incubator-mxnet/pull/19172


   In mxnet we wrap lapack functions in c_lapack_api.h so that we hide the differences in the underlying blas/lapack libraries such as mkl, openblas, atlas, and accelerate. 
   
   For mkl we use/wrap the LAPACKE (https://www.netlib.org/lapack/lapacke.html) c interfaces which are the cleanest. For the rest of the libraries we wrap the old CLAPACK interfaces. 
   
   While atlas and accelerate don't provide the LAPACKE interfaces, openblas does have it. This pr makes mxnet also use the LAPACKE apis when openblas is chosen. 
   
   This will change will make ilp64 blas/lapack support easier as now we have the same wrapping logic or both mkl and openblas. Support for ilp64 mkl https://github.com/apache/incubator-mxnet/pull/19067 will automatically mean support for ilp64 openblas.
