https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/ilp64-documentation/m-p/910107#M12077 I don't find any documentation on the ilp64 version, currently available only for IA-64. It has come to my attention that some customers expect such a library not only to take 64-bit integer arguments, but to take 64-bit real arguments for the BLAS s..... functions, and 128-bit real arguments for d.... functions. Others expect it to resemble a library provided on certain HPUX systems, where the BLAS d... functions apparently take 64-bit integer and real arguments.<BR /> Thu, 21 Sep 2006 21:19:16 GMT TimP 2006-09-21T21:19:16Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/ilp64-documentation/m-p/910107#M12077 I don't find any documentation on the ilp64 version, currently available only for IA-64.
