头文件

请问下怎么没有头文件啊

小而美之外,设计上有哪些考虑?

编译运行的demo并大概浏览了代码,确实是小而美,很不错! 也想请教下亚霏大神在设计deepx_core的一些考虑点

优点
1.小而美,针对推搜广大规模稀疏场景而设计,离散特征、ps、线上server都有解决方案
2.依赖少,编译部署简单,除了libhdfs.so外,一键编译和运行,demo可以很快跑起来
3.基于静态图,可以自定义网络,相比abcus通用性更好
4.代码简洁,没有明显冗余设计

疑问:
1.序列化和反序列化需要自定义代码,是否会考虑用pb
2.目前不支持GPU,未来是否考虑支持
3.计算方面没有采用矩阵库如eigen,性能是否有影响
4.op略复杂(代码量较大),是否有更好的抽象
