| | | | LhsType=RhsType a single generic implementation suffices. For scalars, the generic implementation of pconj automatically forwards to numext::conj, so much of the existing specialization can be avoided. For mixed types we still need specializations.

* Adding lowlevel APIs for optimized RHS packet load in TensorFlowGravatar Anuj Rawat2019-04-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SpatialConvolution Low-level APIs are added in order to optimized packet load in gemm_pack_rhs in TensorFlow SpatialConvolution. The optimization is for scenario when a packet is split across 2 adjacent columns. In this case we read it as two 'partial' packets and then merge these into 1. Currently this only works for Packet16f (AVX512) and Packet8f (AVX2). We plan to add this for other packet types (such as Packet8d) also. This optimization shows significant speedup in SpatialConvolution with certain parameters. Some examples are below. Benchmark parameters are specified as: Batch size, Input dim, Depth, Num of filters, Filter dim Speedup numbers are specified for number of threads 1, 2, 4, 8, 16.

| * Introducing "vectorized" byte on unpacket_traits structsGravatar Gustavo Lima Chaves2018-12-19
|/ | | | | | | | | | | | | | | | | | | | | This is a preparation to a change on gebp_traits, where a new template argument will be introduced to dictate the packet size, so it won't be bound to the current/max packet size only anymore. By having packet types defined early on gebp_traits, one has now to act on packet types, not scalars anymore, for the enum values defined on that class. One approach for reaching the vectorizable/size properties one needs there could be getting the packet's scalar again with unpacket_traits<>, then the size/Vectorizable enum entries from packet_traits<>. It turns out guards like "#ifndef EIGEN_VECTORIZE_AVX512" at AVX/PacketMath.h will hide smaller packet variations of packet_traits<> for some types (and it makes sense to keep that). In other words, one can't go back to the scalar and create a new PacketType, as this will always lead to the maximum packet type for the architecture. The less costly/invasive solution for that, thus, is to add the vectorizable info on every unpacket_traits struct as well.
