Any Yhc Core and/or byte code interpreter available written in e.g. Haskell and/or Java?
by Thorkil Naur 15 Feb '07

15 Feb '07

Hello, I have this crazy idea that I want to run some of my "serious" toy Haskell programs on my pocket phone. To do this, one idea would be to write an interpreter in Java of some very simple intermediate form of Haskell code, such as the Yhc Core format or the Yhc bytecode format. I am primarily interested in something that helps me to understand how to interpret either the Core or the bytecode format, so Haskell interpreters would be most useful. Best regards Thorkil

Yhc: A second impression
by Thorkil Naur 14 Feb '07

14 Feb '07

Hello Yhc'ers, With the correction of bug #18 http://code.google.com/p/yhc/issues/detail?q=&can=2&id=18 I have been able to use Yhc to run a number of my "serious" toy programs, solving important problems like SuDoku puzzles or finding prime factors of large integers. Congratulations, this is most satisfactory. I have a simple benchmark that I have run many times, mostly to compare the performance of different machines. The benchmark consists of running a single program t3 compiled using GHC and measure its CPU usage. This program performs some rather long-winding computations involving large (35-70 decimal digit) numbers that conclude in discovering the second-largest prime factor 1963506722254397 of the "repunit" R[43] = (10^43-1)/9 = 111...(total of 43 1's)...1. On a slow machine that I have used a lot, this takes about 3.5 minutes. On a fast machine, it takes less than 3 seconds. But t3 can, of course, also be used to compare different Haskell implementations on the same machine. So, I have run the following script on my PPC Mac OS X 10.4: #!/bin/sh # t3timing1.sh: Timing t3.hs using GHC, Hugs, Yhc # 2007-Feb-13 19.11 / TN do_ghc () { echo $0: GHC $* time ghc-inplace --make t3.hs $* time ./t3 rm *.hi *.o t3 } ghc-inplace --version time echo :q | ghc-inplace --interactive t3 time echo main | ghc-inplace --interactive t3 do_ghc -O0 do_ghc -O1 do_ghc -O2 time echo :q | hugs t3 time echo main | hugs t3 time yhc t3 time yhi Main rm *.hi *.hbc Essentially, this runs t3 using 4 variants of GHC-support (interpreted and -O0..2) and a single variant of each of Hugs and Yhc. The output, with some non-essentials left out, is: The Glorious Glasgow Haskell Compilation System, version 6.7.20070209 ___ ___ _ / _ \ /\ /\/ __(_) / /_\// /_/ / / | | GHC Interactive, version 6.7.20070209, for Haskell 98. / /_\\/ __ / /___| | http://www.haskell.org/ghc/ \____/\/ /_/\____/|_| Type :? for help.

Overall: For this program (t3), Hugs and Yhc execution times are comparable. Compiled GHC -O2 is 17 times faster. Best regards Thorkil
