Fast Fusion Ring Methods for Computing Braid Group Representations#


Execute a function registered in this module’s mappers in a worker process, and supply the FusionRing parameter by constructing a reference to the FMatrix object in the worker’s memory adress space from its id.


When the parent process is forked, each worker gets a copy of every global variable. The virtual memory address of object \(X\) in the parent process equals the virtual memory address of the copy of object \(X\) in each worker, so we may construct references to forked copies of \(X\).
