Have anybody started working on a linear algebra library on top of ndslice? If not, do you have any wishlist on implementation details?

If not, do you have any wishlist on implementation details?I wrote tiny 'Guide for Slice/BLAS contributors'. It is located in top of ndslice.package. The guide covers base D implementation errors ( I hope so ). Linear algebra can be splitter into BLAS and others. About BLAS: I plan to work on it after voting about ndslice. std.blas is very big project and multiple authors are good. Architecture should be described first. Slice would be very cool instrument to build generic BLAS implementation like boost.nuBLAS but much more flexible and much more faster. Probably it would be world's most fastest BLAS without assembler code. Ideas of implementation are described in Goto's paper: http://www.cs.utexas.edu/users/pingali/CS378/2008sp/papers/gotoPaper.pdf Plus std.blas can use approach from OpenBLAS where are multiplication kernels optimised for special CPUs. Furthermore we can write generic SIMD optimisation logic based on cash level sizes (CASH LEVELS 1 2 3 and RAM). About non-BLAS: You may want to discus it in https://gitter.im/DlangScience/public . Lars wants or wanted to rewrite scid package. -- Ilya
