Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
Notice revision #20110804
The following LAPACK routines are threaded with Intel TBB:
?geqrf, ?gelqf, ?getrf, ?potrf, ?unmqr*, ?ormqr*, ?unmrq*, ?ormrq*, ?unmlq*, ?ormlq*, ?unmql*, ?ormql*, ?sytrd, ?hetrd, ?syev, ?heev, and ?latrd.
A number of other LAPACK routines, which are based on threaded LAPACK or BLAS routines, make effective use of Intel TBB threading:
?getrs, ?gesv, ?potrs, ?bdsqr, and ?gels.
Intel MKL PARDISO Steps
Intel MKL PARDISO is threaded with Intel TBB in the reordering and factorization steps. However, routines performing the solving step are still called sequentially when using Intel TBB.
Sparse BLAS Routines
The Sparse BLAS inspector-executor application programming interface routines mkl_sparse_?_mv are threaded with Intel TBB for the general compressed sparse row (CSR) and block sparse row (BSR) formats.
The following Sparse BLAS inspector-executor application programming routines are threaded with Intel TBB:
mkl_sparse_?_mv using the general compressed sparse row (CSR) and block sparse row (BSR) matrix formats.
mkl_sparse_?_mm using the general CSR sparse matrix format and both row and column major storage formats for the dense matrix.
