Optionally, you can build Schemik using the traditional make command, but it may be necessary to adjust the configuration settings in config.h.

Running Schemik

./schemik -t 0 -- starts Schemik in a sequential mode, i.e., using only one CPU core

./schemik -t 5 -- starts Schemik running in 5 threads

./schemik -t 10 -s scm/fib30.scm -- computes 30th fibonacci number using 10 threads and quits

./schemik -t 10 -c "(define (fib x) (if (< x 3) 1 (+ (fib (- x 1)) (fib (- x 2))))) (display (fib 33))" -- computes 33th fibonacci number using 10 threads and quits
