Re: [lazarus] GPU info
Someone sent me a link to CUDA from Nvidia. After looking at some of the source code it seems that there are two (see below) includes that makes CUDA the numerical processor. include #include #include #include #include #include #include #include #include #include #include Generally, how difficult do you think it is it to interface such includes with FPK or Fortran? Surely they can be wrapped. Users reported a 80x improvement with Cudo on a Gforce compared to a Opteron 2GHZ! The test was single precission though.

[lazarus] GPU info
My question is along the lines of this paper. "http://citeseer.ist.psu.edu/555028.html"; Is there anybody who developed a unit or did any work for using GPU's for numerical computation with FPK/Lazarus? Also, if anyone knows, what are the increase in speed expected over the best Intel or AMD has to offer compared to a current best GPU? Developing a floating point (if such a GPU exists in double or extended precision) unit on a GPU should not be so difficult as the Unit only need to do a few basic elementary functions from which all the remainder of functions and special functions can be obtained. Here is an overview of GPU issues.

Re: [lazarus] going legal, time for a name change....
Florian is right. However, if you want to make someone stop you do have to, because here in the US it becomes a criminal offense if someone continues to use a mark if it is registered. Also, you cannot claim damages if it is not registered. I just won a case against someone so I should know.

Re: [lazarus] Multiprocessing compiler
Thanks Michael and Marco. Conceptually what you did in the Wiki is about how far I thought it through on my own. I wonder if it is not better to completely drop any of the C attempts as it does not really make sense to adapt the non-readability path followed there. I think we all want to avoid that and that is why we are here. Fortran is really the greatest tool for this in my opinion, but maybe a better language to "borrow" from is ADA? I did not look into their archives a lot but they might have solved the same conceptual issues haunting us. There used to be a program on the web years ago that would to some extent parallelize a given binary, but I cannot find the link anymore. Anyone know about it? or something similar? I know this is "poor man's" parallel, and ridiculously inefficient, but it sure makes computational times a bit shorter. Any bit helps. I currently get along by just writing programs in preprocessor-processor-collate fashion which gives me the ability to run things massively parallel across several servers, but it gets bulky with all the file io in between processes. Just forget about load balancing...(dont laugh) this is a crude bash script looking ahead what cpu resources/memory are available and schedule programs accordingly. But, crude as it may sound, it saves me about 6x the time and works great, but at some stage i am going to run into a brick-wall with it.

[lazarus] Cell processor and ppc386/Lazarus
Is there any chance that there will be a compiler for the Sony Playstation Cell processor. As touted, it might just outdo most of the Intel/AMD chips on Floating point and since Floating point performance is all I am interested in, for my work it would be nice to see if it is really better. It would also be nice to be able to compile programs on/for it. I use anything that gives me the better floating point/$ ratio. PSIII It does run linux as you all know. Quoted from wiki. "Linux Gentoo Linux installed on a PS3. Originally Sony stated that they were going to pre-install Linux on the PS3's hard drive, but current units shipping do not include Linux pre-installed. Instead, Sony has made an option in the XMB menu to install other operating systems.[44] Fedora Core 5 and Gentoo have been run on the PS3[45][46]. Fedora Core 5 has, however, not been optimized for the relatively low amount of RAM. The Sony-sponsored Yellow Dog Linux for the PS3 was released on November 27, 2006 to the YDL.net community, and was released on DVD on December 11, 2006, and finally as a publicly available image in late December.[47] “ Because we have plans for having Linux on board [the PS3], we also recognize Linux programming activities… Other than game studios tied to official developer licenses, we'd like to see various individuals participate in content creation for the PS3. ” —on the presence of the Linux in the PS3.

Re: [lazarus] Request for PR noise !
So if you guys want to change the name, where does it leave users like me presenting papers at conferences and citing Lazarus in technical papers as my software of choice? I am asked a lot what software I use and I explicitly promote Lazarus/FPC. This thread make me believe that I will segfault myself to promote Lazarus as the rug will be pulled under serious users feet. Afte this I would rather tell the world I am using Delphi but behind the scenes use Lazarus as I know Delphi I cannot cite Lazarus in papers and then find..oh..it is now called Phoenix. I will in future not cite Lazarus as the name will probably change, but rather give personal credit to the authors who assisted me. Lazarus was a nice way to get around the Pascal-debunkers and it worked well, but I cannot cite something that is so mindlessly considered for rebranding. Usually a name change is associated with public pressure, which would be ok as the world requires it and users promoting it dont have to segfault.

Is it possible to call a Perl program from Lazarus? Perl is quite platform independent but slow, but I can live with that.

Re: [lazarus] Re: Breakpoints not working
You are quite right. Although I am 99% Unix user, I came to the conclusion that Lazarus development on Linux is just not productive. For the exact reason you mention below, using Lazarus on Windows and using Delphi to debug is way more productive. I am actually starting to think that it is the best just to develop in Delphi on windows until a program works and is debugged and then port it to Linux using first Lazarus on windows and then Lazarus on Linux for a final native compile. The option to use a decent debugger as on Delphi makes this a much more efficient process than to develop with Lazarus on Linux. I would have preferred to develop on Linux only as my programs are not used on windows at all, but believe me, developing "pascal/lazarus" code on windows is way more efficient than to use Lazarus's debugger on Linux. It would be a great day when we can have a debugger on Lazarus/Linux which works repeatably and responsibly. If I knew exactly how to improve it I would, but I think we are caught in the trap of the debuggers in Linux which are horribly underpowered ambiguous and idiosyncratic such as gdb. Solving this problem would mean rewriting gdb until it behaves properly. I am not up to that and since the Delphi debugger works so well, I rather develop there and use Lazarus for porting it back to Linux. The good thing about not having a debugger is that I am forced to write vanilla code that must convert to Delphi easily. That is a pretty good thing, so the lack thereof makes you a better programmer, but not a more efficient one time-wise. Felipe Monteiro de Carvalho wrote: If your program doesn't use the form designer it is pretty easy to make it compile on Delphi also. This is what I do, so when I am on Windows I can use Delphi to debug. This is why I am so interested on that "Universar Converter" project to convert the visual forms from Lazarus to Delphi and the other way around.

Re: [lazarus] Breakpoints not working
If Breakpoints step step into etc does work in Laarus it works intermittently according to my eperience. I dont use it anymore as it is not remotely similar in performance to Delphi. I debug by copying the program over and insert extis and cod to print out variable and memory dumps before the steps where I get problems and then move this code down like a breakpoint in order to evaluate where the trouble in my code is. Allthough this takes about 20x longer than Delphi's debuger, it does solve the problem for me, but it is truly inefficient. It would be really nice if Lazarus can have a fast and efficient "means business" debugger that responds in a predictable way at least. So far breakpoints take forever to be reached and the more complex a program becomes the stranger the behavior. This is not a rant, i just describe my experience and hope it would help to make someone look at the debugger as the single most important lacking feature of Lazarus. i understand that it might work for some people, but I believe that is due to the fact that programs are simple. The more complex, the more confusing the debugger behaves. The program copied over to an old version of Kylix debugs really great on Kylix. But, kylix is no more. Joost van der Sluis wrote: Okay, the problem was the stupid user behind the keyboard!! Every time I upgraded to one of the unstable builds, I forgot to actually set the debugger in Environment -> Debugger Options. Sorry for the false alarm. I make this mistake also now and then. Maybe it is an idea to generate a warning, messagebox or something like that if a user has breakpoints in his project and runs the program, but hasn't defined a debugger? Like: "The project has breakpoints defined, but there is no debugger defined in the environment options?

Re: [lazarus] Breakpoints not working
I never got it to work even under Linux during the last 2 years. In linux it takes about half a day to go to the next step in a program. I dont use it anymore, which is a pity.

It is to me the biggest weakness of Lazarus as Borland-like debuggers are essential for anyone who want to migrate to lazarus.
