raingo / caffe-mpi Goto Github PK

Your sgd-mpi implementation is a littlle confusing. It seems like that each worker uses parameters updated by itself last time, instead of pulling current parameters in the server.
I think it should import more bias in the computation, because its time delay is larger.

I compiled the code, and got the errors below. Do you need to update your code to make it compilable with latest Caffe functions? Please correct me if I'm wrong.
