Description
Pcard-70459
优化 FA 编译,当 bos 上有 cache 时,不进行实际的编译,而是从 bos 上直接拉编译好的 so
打包 cache 方法:
1、进入到
third_party/flashattn
目录中获取gitcommit
2、创建
flashattn_libs_*gitcommit*
文件夹3、创建
fa_libs
文件夹,然后将编译完成的 sobuild/third_party/install/flashattn/lib/lib*.so
拷贝进去。4、执行打包操作
tar -cf fa_libs.tar fa_libs
5、执行
md5sum fa_libs.tar
获取 MD5SUM 值,写入到MD5.txt
文件中6、执行
tar flashattn_libs_*gitcommit* flashattn_libs_*gitcommit*.tar
命令整体打包7、上传到 bos
文件名命名规则:
flashattn_libs_*gitcommit*.tar
