worker threads use addprocs and pass -t/--threads as exeflags. Multiple GC Threads The Garbage Collector (GC) can use multiple threads. The amount used is either half the number of com- pute worker threads considered unsafe because converting an object to a native pointer can hide the object from the garbage collector, causing it to be freed prematurely. Type Correspondences First, let's review some relevant Julia Julia, after the @ccall returns, you must ensure that the object remains visible to the garbage collector. The suggested way to do this is to make a global variable of type Array{Ref,1} to hold these values
