The specific optimization and general support for the latest Intel® AVX2 instructions have been added in the Intel MKL v11.0. This article lists the specific functions that are optimized for Intel AVX2.
Sparse BLAS routines can be useful to implement iterative methods for solving large sparse systems of equations or eigenvalue problems
Intel® SGX Code Sample: Learn how to mix enclaves with managed code on Microsoft Windows* platforms using the C# language. There are multiple solutions for accomplishing these tasks, and this article and its accompanying code sample demonstrate one approach.
Enclaves must be 100 percent native code and the enclave bridge functions must be 100 percent native code with C (and not C++) linkages, it is possible, indirectly, to make an ECALL into an enclave
