GR nation,

My first attempt at this question was foiled by my e-mail program’s  
insistance on sending html. I apologize for the repeat.

I am interested in using controlport for monitoring, debug, and control  
of a flowgraph as part of a larger distributed signal processing  
system. I’m currently running GR 3.7.4 so I still have Ice but the rest  
of my system uses zeromq. I’d like to remain consistent and I’d like to  
have something independent of the GR version (Ice seems to have been  
removed from later versions). The controlport documentation states that  
it’s agnostic to the rpc framework, but I cannot figure out how one  
would use a service other than through Ice. In fact I can’t even find  
where the Ice server is setup in the flowgraph and how the server  
discovers the registered rpcs from each block. Any suggestions would be  
appreciated.

Jared.

The design of ControlPort was that we could put in other RPC/middleware  
layers between the ControlPort API used by GNU Radio and the client  
side.  
We had only developed this using ICE so far, though. There is an effort  
to  
add support for Thrift inside ControlPort, though, and we are hopeful  
that  
we can re-enable the use of ICE in the near future.
