(not a problem report, just thought some of the people here might find it
interesting- CMud 3.0 and zMud 7.21)
I've been doing some math calc benchmarking and fired up CMud and zMud out of curiosity. This particular test was Euclid's algorithm, straight out of Sedgewick (not using the mod operator).
On a P4 1.7, zMud took about .22 or .23 seconds to run a sample problem. On the same machine, CMud manages about .03 seconds (for code which can run in both, which looks a little clumsy to get both parsers to accept it). CMud seems able to get down to around half that if you start using local variables and other tweaks.

base code, paste into new alias with name gcd:
#var start 1;#var end 1;#var start %time(z);#var u %1;#var v %2;#while (@u > 0) {#if (@u < @v) {t = @u;u = @v;v =@t;};#var u %eval(@u-@v)};#say "GCD:" @v , %eval(%time(z) - @start)
gcd 461952 116298
should display a correct answer of "18" and the time elapsed. If you see a negative time elapsed, that's because the second rolled over during the test. |
