Description
pcard-71500
cublaslt gemm algo search code optimization and support load algo caches file generated by offline.
Usage
离线配置文件可由tune_cublaslt_gemm算子生成，并放到指定路径下。加载离线文件配置(FLAGS_cublaslt_device_best_config)需启用cuBLASLT全局搜索(FLAGS_enable_blaslt_global_search)后才生效
cache file format
format(each line): M,K,N,algoId,swizzle,customOption,tile,splitK_val,reductionScheme,stages,workspaceSize,time
example: 2048,2048,4096,21,0,0,24,8,3,15,0,0.0701338
