Userspace program #7

Closed bueryg closed 5 years ago

bueryg commented 6 years ago

There are only three example programs under lite-userspace. So I am confused about how to use these functions to write my own program.Do I need to read the source code and learn about these functions' usage?

Not really. The APIs you could call from userspace basically can be separated into three types

  1. rpc style
  2. one-sided rdma style
  3. management function For all the usage of rpc style APIs, (including send, receive, and reply), you could see lite-rpc to find the basic use case. It also needs to register and query port, and the example is also provided in lite-rpc. For all the usage of rdma style APIs, (including write, read, c&s, f&a), you could see lite-write to find the basic use case. alloc_remote_call is also included in lite-write For management function such as barrier and join, I think you could find the example under three examples. And get_node_id and get_total_node is basically let you know the node_id and total number of nodes.
