By default, FEMLISP starts in serial mode (this may change in later versions). You can allocate a new worker pool by issuing the command
This should allocate a worker pool (a “kernel”, as the underlying
lparallel calls it) which is adapted to your machine’s
architecture (more precisely, it depends on how much Femlisp can find
out about it using the system command “lscpu”).
Alternatively, you can give
new-kernel as parameter the number of
workers which you want to use.
