The Brook+/CAL application, otherwise known as plan class "ATI14", are now available for Windows and Windows 64. They are based on the 2.09 applications, but with the additional solo_collatz verification added. They utilize the same command line settings as the Collatz v2.09 ATI applications. Anyone with an AMD HD 2400 or later GPU can once again participate. In addition, those with AMD OpenCL compatible GPUs can choose via their preferences whether to run the ATI14 apps, the OpenCL AMD apps, or both.

Recent AMD video drivers, especially those installed for Windows 8 and even some for Windows 7, may not install the necessary CAL DLLs and therefore cannot run the Brook+/CAL application. Try as I might to manually install them, I had to downgrade a laptop with an ATI Mobility HD 3200 GPU from Windows 8.1 to Windows 7 and also install an older version of the AMD video drivers in order to even test the solo_collatz Brook+/CAL application. Given that Brook+ has not been supported by AMD for a number of years and new AMD GPU hardware cannot run CAL applications, it is not all that surprising. So, if you have an older AMD Radeon HD series GPU that cannot run OpenCL applications and you want to continue to use it to run ATI applications with Collatz or other BOINC projects, you may want to avoid future AMD video driver upgrades.

I used to get the mini_collatz cal_ati version in my AMD ATI Radeon Mobility HD 5145/4570 (R710, driver cal 1.4.635, openGL 6.14.10).
But I am not getting any of the new solo ati14 version on this GPU.
Will there be a cal_ati version of the solo application?
Thanks

Hey, you asked for tests a while ago. I'm running Collatz fine on two ATI cards:
1. Mobility Radeon HD 3650 on Windows 7 x64, Catalyst 9.12 (core driver 8.681, CAL 1.4.515), http://boinc.thesonntags.com/collatz/show_host_detail.php?hostid=139480
2. FireGL V7700 (RV670 chipset, same as Radeon HD 3800) on Windows XP x64, FireGL driver (not Catalyst) 8.634 (which gives CAL 1.4.344), http://boinc.thesonntags.com/collatz/show_host_detail.php?hostid=141064

But: I'm really used to work on Linux - any news on Linux front? I'm refering to part of conversation http://boinc.thesonntags.com/collatz/forum_thread.php?id=1113 about legacy ATI drivers in repositories of modern Linux distibutions.

If you have a 32-bit Linux client, give the new app a try.

Problem with the Ati14 tasks and the open-cl tasks: They both have the same short name "Solo_Collatz". The problem with having the same short name is that GPU exclusions in the boinc config.xml file use the short name. Thus when I exclude solo_collatz from device 0 (an opencl capable HD5850) so that the ati14 will run on device 1 (a non-opencl integrated HD3000), this causes boinc to run the opencl solo_collatz on device 1 also, of course it not being able do opencl should cause the task to fail, but it is not, the work is either being done on device 0 (HD5850) or the cpu.

For the exclusions to work the opencl and ati14 really need to have a different short name.

Have you excluded one or the other in your preferences? You can choose one or the other or both.
