Christoph Ruegg	d3dc54b4c1	Reworking common parallelization routines #92	14 years ago
Iain McDonald	8e1cd36027	Alter parallelisation of matrix multiplication I empirically noticed that matrix multiplication was extremely slow for the matrices I was using i.e. multiplications were taking minutes rather than seconds. After tracking down the root of the problem, I found it was in the CacheObliviousMatrixMultiply() implementation, specifically, where the sum of the column/row dimensions were compared with the Control.ParallelizeOrder variable. For significantly skewed matrix multiplication (wide * tall), the parallelised redistribution greatly reduces performance. By removing the 'k' parameter from the comparison (where k is the number of columns in the left matrix and the number of rows in the right) the performance is improved drastically. For perfectly square matrices, this change reduces performance slightly.	14 years ago
Christoph Ruegg	d65354f4b8	Native Pull: Updated provider and bug fixes mathnet-numerics-native a6e5c948049bda46cb3b5625fa41accebaa4bdb3: 1. Updated the native provider to MKL V11 update 2, which fixes the lange bug. 2. Re-enabled native matrix norms. 3. Fixed complex Frobenius norm bug in managed code (we weren't taking the conjugative transpose). 4. Fixed the return type on the double matix norm in the managed side of the native provider.	14 years ago
