[Gretl-users] When Julia is faster than C and Gretl

Dear all, I just stumbled about this Julia post https://www.juliabloggers.com/when-julia-is-faster-than-c/ and translated the code to hansl. Running the original Julia code on my machine with 10^7 iterations takes about 0.19 seconds. Running the hansl code below takes about 19 seconds which is 100 times slower compared to Julia. I am pretty sure there is a much more efficient way to set this up this up using gretl+hansl (Jack? :-D ) -- but this is not my point. Let's just assume the average user would set up things as simple as possible. I am just curious to know at which point Julia makes it seemingly better compared to C and hansl? Any ideas? Btw, I can't see that Julia makes any use of parallelization -- according to CPU information only a single core is fully used. The same holds for gretl. <hansl> function void euler(int n, scalar *mn) # pointer form scalar m = 0 loop i = 1..n -q scalar the_sum = 0 loop while the_sum<=1 -q m++ the_sum += randgen1(u,0,1) endloop endloop mn = m/n end function set verbose off clear set stopwatch scalar mn = 0 euler(10^7,&mn) # originally 10^8 printf "This took = %.6f sec.\n", $stopwatch mn <hansl> Best, Artur
