* 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
* Include stdint.h. Not going for cstdint because it is a C++11 addition. ↵Gravatar Benoit Jacob2015-03-16
| | | | Needed for uint16_t at least, in lookup-table code.
* 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

* organize a little our default cache sizes, and use a saner default L1 ↵Gravatar Benoit Jacob2015-03-13

* 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

* 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.

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