| * Similar to cset 3589a9c115a892ea3ca5dac74d71a1526764cb38Gravatar Benoit Jacob2015-03-16
| | | | | | | | , also in 2px4 kernel: actual_panel_rows computation should always be resilient to parameters not consistent with the known L1 cache size, see comment
| * fix bug in maxsize calculation, which would cause products of size > 2048 to ↵Gravatar Benoit Jacob2015-03-16

| * Update Nexus 5 lookup table from combining now 2 runs of the benchmark, ↵Gravatar Benoit Jacob2015-03-16

| * bug #973, improve AVX support by enabling vectorization of Vector4i-like ↵Gravatar Gael Guennebaud2015-03-13
| | | | | | | | types, and enforcing alignement of Vector4f/Vector2d-like types to preserve compatibility with SSE and future Eigen versions that will vectorize them with AVX enabled.
| * Fix internal::random(x,y) for integer types. The previous implementation ↵Gravatar Gael Guennebaud2015-03-13
| | | | | | | | could return y+1. The new implementation uses rejection sampling to get an unbiased behabior.
| * bug #949: add static assertion for incompatible scalar types in dense ↵Gravatar Gael Guennebaud2015-03-13
| | | | | | | | end-user decompositions.
| * SparseMatrix::insert: switch to a fully uncompressed mode if sequential ↵Gravatar Gael Guennebaud2015-03-13
| | | | | | | | insertion is not possible (otherwise an arbitrary large amount of memory was preallocated in some cases)
| * Bound pre-allocation to the maximal size representable by StorageIndex and ↵Gravatar Gael Guennebaud2015-03-13

| |
| * bug #978: early return for vanishing productsGravatar Gael Guennebaud2015-03-06
| |
| * Improve blocking heuristic: if the lhs fit within L1, then block on the rhs ↵Gravatar Gael Guennebaud2015-03-06
| | | | | | | | in L1 (allows to keep packed rhs in L1)
| * Improve product kernel: replace the previous dynamic loop swaping strategy ↵Gravatar Gael Guennebaud2015-03-06
| | | | | | | | | | | | by a more general one: It consists in increasing the actual number of rows of lhs's micro horizontal panel for small depth such that L1 cache is fully exploited.
| * Rename LSCG to LeastSquaresConjugateGradientGravatar Gael Guennebaud2015-03-05

| * Product optimization: implement a dynamic loop-swapping startegy to improve ↵Gravatar Gael Guennebaud2015-03-05

* | | Added support for 32bit index on a per tensor/tensor expression. This ↵Gravatar Benoit Steiner2015-02-27
| | | | | | | | | | | | enables us to use 32bit indices to evaluate expressions on GPU faster while keeping the ability to use 64 bit indices to manipulate large tensors on CPU in the same binary.
* | | Switch to truncated casting when converting floating point types to integer. ↵Gravatar Benoit Steiner2015-02-27
| | | | | | | | | | | | This ensures that vectorized casts are consistent with scalar casts
