Title: Is it possible to parallel processing with LISP?
Post by: nokiya2000 on May 12, 2011, 08:11:49 PM: HI~ Guys , This is my second thread.

I live in Korea and work as GIS Engineer. When I work, I usually used Autodesk Map3d 2008.

I 'm not good at Lisp Programming. But i can programming what I want .

Someday , I'm wondering about Parallel processing with VLISP.

So I tried to parallel programming by LISP.

But There was so many things to solve.

So I want to ask you guys about Parallel Processing.

Is it possible to parallel processing?

Thanks for reading this thread.

Well, Then What language is good to parallel programming? Dot net ? or...

AutoCAD API functions are not thread safe so you can use multiple threads or have ones that do background processing but only the main process can interact with AutoCAD.

Perhaps improved algorithms can increase the speed of the program.

My friend have finished this challenge.Now I just show some demostrations.
I read his code,it's made of VLISP,just added a line of VBS into it.
For some reasons,I didn't post his code.

Yea , That's why i need to parallel programming.

I actually draw Cross section by lisp.

It was kind of stupid thing when i work.

Wow!!! As you mention, Noting is impossible.

HOw did your friends do multiple tasking like that?

I'm so wondering about it. ...

what version of autocad can use this program?
Will it work on autocad 2010-2012?

Any version that greater than R13 .
I think so. I tested it on AutoCAD 2012,Windows 7.It works well.

I have another way:
Create it by some API functions. for example: Use VBA statements or "DynamicWrapperX" to declare some functions about Thread.
Code: [Select]
Declare Function CreateThread Lib "kernel32" Alias "CreateThread" _ (lpThreadAttributes As SECURITY_ATTRIBUTES, _ ByVal dwStackSize As Long, _ lpStartAddress As Long, _ lpParameter As Any, _ ByVal dwCreationFlags As Long, _ lpThreadId As Long) As LongThen use VL.application to call it.
