* GEMM + Reduce max fp16+fp32 * GEmm + Max bf16 + int8 * Refactor common definitions. * Refactor common func of mean meansquare example. * More examples for mean meansquare. * Update int8 examples and skip them cause of random errors. * Int4 examples. * Fix examples for max int4/8 * Tensor conversion for int4 input data for mean meansquare example. * Remove int4 mean_meansquare example * Fix int8 mean_meansquare example. -All ReductionAccData and R<N>DataType have to be F32. The INT32 data type is giving wrong results. * Guard int4 with ifdef * Change int8 example to add_addsquare due to div rounding err. * Clang format * Change the return type of common function. * Get back int8 example with division. * Remove int8 mean meansquare. * Use proper cast for BF16 data type. * Use ck::literals. * Use proper data type for host tensors & reference. - Use ReduceAccDataType for reference gemm output data type. - Cast host reference output tensor to EDataType - Fix ifdefs for int4.

// Every binary operator used in reduction is represented by a templated functor class. Each functor
|
|
// class must provide at least
|
|
// three members:
|
|
// 1) GetIdentityValue() -- the interface to return the "identity element" for the binary
|
|
// operator, "identity element" is the unique
|
|
// element in the algebraic space that doesn't affect the value of other elements
|
|
// when operated against them, and the concept is similar to zero vector in
|
|
// vector space
|
|
// (http://pages.cs.wisc.edu/~matthewb/pages/notes/pdf/linearalgebra/VectorSpaces.pdf).
|
|
// 2) IsCompatibleInMemoryDataOperation() -- return true if the reduction task corresponding to this
|
|
// operator can use the InMemoryDataOperation to finalize, or else it return false
|
|
// 3) operator() -- the first argument of the operator must be both an input & output, and the
|
|
// corresponding variable usually stores
|
|
// the accumulated result of many operator() calls; the second argument is only an
|
|
// input. For indexable binary
|
|
// operator, the second version of operator() has third argument (which is an
|
|
// output) to indicate whether the
|
|
// accumulated value (the first argument) has changed, in which case the recorded
|
|
// accumulated index also need be
|
|
// changed.
