Zha0q1 opened a new issue #18926: 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 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
