I'm not familiar with Julia, but I'd offer two possible points to consider: * If Julia code can be compiled to a library exposing C interface (as Go makes possible on some platforms with the compiler's option -buildmode=c-archive), you can do just that and the call it from Go via the standard Go's cgo facility. * You may consider an often overlooked approach to just not embed anything to anything else and instead employ IPC (inter-process communication). Say, you could possibly compile your Julia program so that it reads data in certain agreed-upon format on its stdin and writes the results of processing them to its stdout. Your Go server then merely starts your Julia program and wires two pipes to those standard I/O streams of the process it created. Communication then becomes a matter of writing stuff to one of those pipes and then reading the result from another one. If your Julia server need to be multithreaded, it's possible to use "job identifiers" with each task submitted to that Julia process; this would allow the latter to perform the jobs in parallel and use those job IDs in its answers which then could come out the result pipe in any order. Certainly the latter approach is slower than the first but it's definitely easier to implement and to reason about, and it fully decouples both programs. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
