VMA does not support more then 1 epfd listed

[highfly22]

I got the following log when running a distributed Tensorflow training job. In socket_fd_api::add_epoll_context function, there is a comment "Currently VMA does not support more then 1 epfd listed". Is there any plan to support that feature? Thanks!

Hi,

Multiple epfd's support has been tested in the past but caused performance degradation.
Hence, there are no plans to support this feature.

Thanks,
