* initial stub for standalone softmax * start device_softmax_mk_to_mk as a wrapper to device_reduce_mk_to_m * host softmax validates * compiles; to implement beta scaling * use NaN trick to efficiently ignore OOB values during sum of exponentials * freeload device_reduce's utility functions * clean up interface * adding prior value (beta scaling) * remove restriction related to perf considerations * apply clang-format * clean; disable diagnostics * resolve conflicts * add exp wrapper * honor HostTensorDesc interface; allow implicit cast from different vector<T> type * test softmax for fp16/fp32 * update readme * amend commit NaN trick * remove redundant param added during development * format * replace ScalarDataType with AccDataType * separate out test programs by precision type * move softmax sample code to its own folder * format * keep up with recent changes in reduction API * remove extra header
