Big Thanks for You Jason for the effort and good job You are doing. We're all waiting for the new improvements.

I'll wait and see if Guy wants to wait for the new, fast and beautiful or if he is willing to go for another try with the old one. If the latter I can PM when requested.

I'll keep my personal baby steps in Cuda and OpenCL programming in small circles and even then try to document what and maybe why I have made some changes if any.

I can get a diff on my HDD if I can download the version I started with. I'm not familiar with svn, but I'm sure there is a way to get a certain revision to my PC again. Or even better if svn can tell me the difference from my hdd content against to a certain version.

My suggestion for now is to stick with the 'old' (plus your improvements :)). Sorting out x42 is proving to be a monumental effort :)

Yeah there's a svn diff command that would compare yout working copy with the original and make a single file with a bunch of +'s and -'s , very handy.

If you have the files separate, not under version control, I would do a fresh svn checkout, paste the changed files over the top, then do the diff. It'll work it out exactly as you're thinking.

Keep poking at it. You're fiddling in areas I haven't touched since around Fermi introduction, so there's plenty of legroom. The challenge for me now is to make sure I get x42's polymorphic behaviour right, so that hardware that likes it gets it.

If you describe what and why changes you did in OpenCL kernels I could imclude those changes in main tree.

PM coming soon.

I send you the AstroPulse_Kernels_r1952.cl I currently run. It has 3 functions/kernels that have changed and they have comments what and why. There may be other minor changes, but diff helps.

I have not got the original source and I have lost my benchmark run times, so You may want to bench them first.

Hi Guy,

So, ya, sure, send me what you got Petri. I sure appreciate the help.

The zip file is quite big. About 150 megabytes. I'll figure out a way to get You access to it.

I'll make another zip that has executables, app_info.xml and libraries.

Even after that there is a possibility that You can not run them, due to version incompatibilities. I'm running and have compiled all on 64bit Fedora 14, with an updated compiler and Cuda 5.5.

No wories Petri, if it's too much trouble, don't worry about it. I'll wait until it gets implemented and distributed through the Seti servers. All I'm lacking, as far as I'm concerned, is a Linux/Nvidia/MB app. I can live with out it for a while, it's not going to reduce my RAC because these are additional PCs to what I'm running now.

I'm not sure I could compile from source and get it to work anyway. My experience with gcc is limited, to say the least.

I appreciate the thought, though.

OK, better to wait. And from what I have understood there are some real advancements in the 'new'.

Forgot to mention, I installed OpenCL from the Fedora repositories and it looks like I have OpenCL version 1.0. Maybe version 1.1 is needed? Also downloaded the SDK and installed it.
...

If I remember correctly I have not downloaded any extra packages to get OpenCL. I have a feeling that it comes with the NVIDIA driver.

I have to install the driver under init 1 on my machine and kill X before installing. then just reboot.

Gary Roberts of Einstein is doing some interesting research into GPU crunching on Linux - primarily with AMD/ATI, but I think there may be some crossover here.

What caught my eye was

... other things I've read make me think that I don't really need the SDK but rather the 'Installable Client Driver' (ICD) stuff that ends up in /etc/OpenCL/vendors/.

Which makes a heck of a lot of sense for an end user.

chmod'd and chown'd all files after unzipping. boinc:boinc rwxrwxrwx still gives the permission denied error.

Did you also change the directories (including the parent)? BOINC needs write access to directories in order to create new files.
