Comment (by humasect):
Yes, I almost thought this would do it, there is no error when executing
GHCi this way. But actually:
4.12.1. Options to enable SMP parallelism
In order to make use of multiple CPUs, your program must be linked with
the -threaded option (see Section 4.10.7, “Options affecting
linking”). Then, to run a program on multiple CPUs, use the RTS -N
option <cut>
Would this only mean that GHC needs to be instead built with -threaded
+RTS -Nx for this ability? We need the computing power over here.
