Hi! I have the similar question: Is it possible to call RProvider functions in parallel? For example cal R.lm from different Threads/Tasks (PLINQ) simultaneously?
As far as I understand it, the underlying R engine can only be called from a single thread - so only a single thread can access it (and additionally, I think it also starts doing odd things when you call it from multiple threads, even when the calls are not concurrent).
In principle, I suspect that you can create multiple instances of the R.NET engine (@jmp75 would probably know), but this is not something that we are currently exposing in the R type provider (you cannot really currently initialize the R provider multiple times in a single process).
I tried calling R from a parallel loop but it fails with
Error: unprotect_ptr: pointer not found
, the sequential version works without problems.
