URL: https://github.com/apache/incubator-mxnet/issues/18926


   https://github.com/xianyi/OpenBLAS/issues/2779
   Please refer to ^ this issue. Float point behaviors are different in ILP64 
OpenBLAS and the vanilla 32-bit LP64 OpenBLAS due to difference in the usage of 
FMA/blocking. Essentially we will lose precision when two float numbers are 
more than significand apart. This is better handled by vanilla openblas and 
hence we may get different numerical results on same inputs migrating to ILP64 
openblas when using gemm, gemv, and others.
   
   We should discuss the implication of this issue before preceding to migrate 
to ILP64 openblas
