speaking about the Bible, reminds me of two movies

(just for fun tho..)

1. Book of Eli: Just because of one book, but they didn't know that that last Bible was in braille

2. Love Guru: BIBLE = Basic Instructions Before Leaving Earth

Wrote on the subject of about LISP performance at Aug. 2, 2013, 2:27 a.m...

Hi LISP gurus

Was playing with Lisp on my WinXP and was wondering why this large difference of performance.

I got GNU Emacs and CLISP on my WinXP laptop. I run these following codes respectively:

Code:

(defun silly-loop (n)

"Return the time, in seconds, to run N iterations of a loop."

(let ((t1 (float-time)))

(while (> (setq n (1- n)) 0))

(- (float-time) t1)))

Code:

(defun silly-loop (n)

"Return the time, in seconds, to run N iterations of a loop."

(let ((t1 (get-universal-time)))

(loop while (> (setq n (1- n)) 0))

(- (get-universal-time) t1)))

For emacs, the result is 10 seconds if using interpreter, then 3 seconds if using byte-code.

But for CLISP interpreter, it’s a horrible 48 seconds, I was wondering what’s the difference? And why such a large gap? Maybe CLISP VM is stack-based while emacs is something maybe register-based?

Thanks in advance, ciao!

could you recommend a great book/pdf to learn emacs' implementation of lisp? Or maybe better, sbcl or any other "advanced" clisp?

hi mia, sorry but i usually use the net to search specific commands, also did use the emacs tutorial inside emacs too.. but for a Lisp pdf, now im reading Practical Lisp

also i mentioned that video from MIT but i just know it was Scheme that they taught hehe but still useful

hi robes! geez silly me i forgot to put it here, thanks

its:

Code:

(silly-loop 50000000)

today i will try compile it on CLISP byte-code to see the difference..

Wrote on the subject of about LISP performance at Aug. 2, 2013, 7:28 p.m...

some update. i was able to compile it on CLISP and here is the result:

Code:

D:\>clisp -q -norc test.fas

7

D:\>clisp -q -norc test.lsp

47

compiler = 7 secs
interpreter = 47 secs

compared to emcas lisp:
compiler = 3 secs
interpreter = 10 secs

all on the same machine, does it mean the VM is the difference?

A CL interpreter has more to do, since there can be symbol-macros and handlers and restarts and things that need to be managed.

so does it mean emacs interpreter only manage a few things that's why it was faster?

but how about the compiled byte-code, byte-codes should run on VM's right? what i know is CLISP use a stack-based VM for their byte-code while im not sure for emacs. but comparing the compiled performance, emacs still has beaten CLISP many folds so i wonder how emacs lisp did this, is it the VM design they use? btw please correct me, all byte code generated by LISP compilers will be run by their own VM's right? not the interpreter?

yeah.. i even thought maybe Lisp could be used on bitcoin mining? not sure if i understood it right.. oh! i already got Kogge's book from Amazon, i cant stop reading hehe but now im kinda busy with BLE stuff.. get back with SGI and LISPM soon, cheers!!

Wrote on the subject of Iverilog 0.9.7 at July 30, 2014, 5:38 p.m...

Morning everyone!

I'm working on a Verilog project now and want to try it on my O2. I installed the one from nekoware but it seems that version is too old and some feature that i use is not yet there which causes too many errors

So i want to port the latest if possible. I was able to get until './configure', when i did 'make' it complains on some syntax. so i use 'gmake' then it compiled but using MipsPro and because of this it has many warnings and finally an error about namespace?

so my question is should i do the port in MipsPro or should i adjust some file so that it would use gcc/g++ for compiling?

thanks in advance!

BR,

hi ham!!

hamei wrote: These days you almost always have to use gmake ... check the rest of your ./configure setup as well, nekoware has fairly current versions of all the required programs.

oh! i see, so ok then 'gmake' will it be then.. ok will check more about the generated 'configure' file and see what else i need.. but i thought that once 'gmake' is used, it will also automatically use 'gcc/g++' as its default compiler? its not right so ok..

hamei wrote: Up to you what you use, but if you try MIPSPro there are several people here who will help, if you want to slog your way through it. Can learn something that way ...

ah ok hmmm the advantage of MIPSPro is it more optimized right? but ok will face those warnings and errors man-to-man then.. wish me luck!! and will just ask later once i hit some road blocks, thanks!!
