Using MKL, the Intel Math Kernel Library (v11.0.0.079) - ICHEC

•Interface LayerThis layer provides matching between the compiled code of an application and the threading/computationalcomponents of the library. This layer:•provides an LP64 interface.•access to MKL ILP64.•deals with the way in which different compilers return function values.•a way to map single precision names to double precision names in applications that employ ILP64programming model (e.g. Cray-style naming).Interface Layer Librarieslibmkl_intel_lp64 libmkl_intel_ilp64 libmkl_gf_lp64 libmkl_gf_ilp64 libmkl_intel_sp2dp•Threading LayerThis layer helps the threaded MKL to co-operate with compiler level threading. This also provides thesequential version layer.Threading Layer Librarieslibmkl_intel_thread libmkl_gnu_thread libmkl_pgi_thread libmkl_sequential•Computational LayerThis is the heart of MKL and has only one variant for any processor/operating system family, Thecomputational layer accommodates multiple architectures through identification of the architecture orarchitectural feature and chooses the appropriate binary code at execution. Intel MKL may be thought of asthe large computational layer that is unaffected by different computational environments. Then, as it has noRTL requirements, RTLs refer not to the computational layer but to one of the layers above it: the Interfacelayer or Threading layer. The most likely case is matching the threading layer with the RTL layer.Computational Layer Librarieslibmkl_avx libmkl_core libmkl_def libmkl_mc/mc3 libmkl_scalapack_lp64/ilp64libmkl_vml_def/p4n/mc/mc2/mc3/avx/cmptlibmkl_cdft_core2
