* fix compile error * fix typo of padding * Add smoothquant op * Add smoothquant instance library * refine type * add test script * Re-generate smoothquant.hpp * Always use 'current year' in copyright * use Generic2dBlockShape instead * Add vector = 8 instance back * Find exe path automatically * Simplify the api condition * Remove debugging code * update year * Add blank line between function declaration * explicitly cast return value to dim3 * refine return value * Fix default warmup and repeat value * Add comment * refactor sommthquant cmake * Add README * Fix typo --------- Co-authored-by: Po Yen, Chen <PoYen.Chen@amd.com>
