Note, CUTLASS epilogues universally target row-major outputs. Column-major outputs are accommodated by exchanging A and B operands and assuming transposed layouts. Partial specializations here choose 'device::GemmTransposed' to implement this functionality. */ #pragma once #include "cutlass/cutlass.h" #include "cutlass/complex.h" #include "cutlass/layout/matrix.h" #include "cutlass/numeric_types.h" #include "cutlass/gemm/kernel/gemm_grouped.h" #include "cutlass/gemm/kernel/gemm_transpose_operands.h" #include "cutlass/gemm/kernel/default_gemm.h" #include "cutlass/gemm/kernel/default_gemm_complex.h" #include "cutlass/gemm/device/default_gemm_configuration.h" #include "cutlass/layout/permute.h" ///////////////////////////////////////////////////////////////////////////////////////////////// namespace cutlass { namespace gemm { namespace kernel { ///////////////////////////////////////////////////////////////////////////////////////////////// template < /// Element type for A matrix operand typename ElementA_, /// Layout type for A matrix operand typename LayoutA_, /// Complex elementwise transformation on A operand ComplexTransform TransformA, /// Access granularity of A matrix in units of elements int kAlignmentA, /// Element type for B matrix operand typename ElementB_, /// Layout type for B matrix operand typename LayoutB_, /// Complex elementwise transformation on B operand ComplexTransform TransformB, /// Access granularity of B matrix in units of elements int kAlignmentB, /// Element type for C and D matrix operands typename ElementC_, /// Layout type for C and D matrix operands typename LayoutC_, /// Element type for internal accumulation typename ElementAccumulator, /// Operator class tag typename OperatorClass, /// Tag indicating architecture to tune for typename ArchTag, /// Threadblock-level tile size (concept: GemmShape) typename ThreadblockShape, /// Warp-level tile size (concept: GemmShape) typename WarpShape, /// Warp-level tile size (concept: GemmShape) typename InstructionShape, /// Epilogue output operator typename EpilogueOutputOp, /// Threadblock-level swizzling operator typename ThreadblockSwizzle, /// Number of stages used in the pipelined mainloop int Stages, /// Whether the schedule of problems to visit has been precomputed GroupScheduleMode GroupScheduleMode_ = GroupScheduleMode::kDeviceOnly, /// Operation performed by GEMM typename Operator = typename device::DefaultGemmConfiguration< OperatorClass, ArchTag, ElementA_, ElementB_, ElementC_, ElementAccumulator>::Operator, /// Use zfill or predicate for out-of-bound cp.async SharedMemoryClearOption SharedMemoryClear = SharedMemoryClearOption::kNone, /// Permute result D typename PermuteDLayout = layout::NoPermute, /// typename Enable = void > struct DefaultGemmGrouped; ///////////////////////////////////////////////////////////////////////////////////////////////// // // Real-valued GEMM kernels // template < /// Element type for A matrix operand typename ElementA, /// Layout type for A matrix operand typename LayoutA, /// Access granularity of A matrix in units of elements int kAlignmentA, /// Element type for B matrix operand typename ElementB, /// Layout type for B matrix operand typename LayoutB, /// Access granularity of B matrix in units of elements int kAlignmentB, /// Element type for C and D matrix operands typename ElementC, /// Layout type for C and D matrix operands typename LayoutC, /// Element type for internal accumulation typename ElementAccumulator, /// Operator class tag typename OperatorClass, /// Tag indicating architecture to tune for typename ArchTag, /// Threadblock-level tile size (concept: GemmShape) typename ThreadblockShape, /// Warp-level tile size (concept: GemmShape) typename WarpShape, /// Warp-level tile size (concept: GemmShape) typename InstructionShape, /// Epilogue output operator typename EpilogueOutputOp, /// Threadblock-level swizzling operator typename ThreadblockSwizzle, /// Number of stages used in the pipelined mainloop int Stages, /// Whether the schedule of problems to visit has been precomputed GroupScheduleMode GroupScheduleMode_, /// Operation performed by GEMM typename Operator, /// Use zfill or predicate for out-of-bound cp.async SharedMemoryClearOption SharedMemoryClear, /// Permute result D typename PermuteDLayout > struct DefaultGemmGrouped< ElementA, LayoutA, ComplexTransform::kNone, // transform A kAlignmentA, ElementB, LayoutB, ComplexTransform::kNone, // transform B kAlignmentB, ElementC, LayoutC, ElementAccumulator, OperatorClass, ArchTag, ThreadblockShape, WarpShape, InstructionShape, EpilogueOutputOp, ThreadblockSwizzle, Stages, GroupScheduleMode_, Operator, SharedMemoryClear, PermuteDLayout, typename platform::enable_if< !
