why is cuda linux missing from download area?

(1/2) > >>

BeemerBiker:
I found the setiathome-CUDA-6.08.X86_64.tar in the first post of the seti cuda thread.  Is there any reason why it is not in the download area?  The files are dated 1/18/2009 and I was woindering if that is still good for the latest and greatest ubuntu 9.1.  I have a GTS-250 which is not double preciision.  It seems to run fine for einstein and gpugriid cuda on 9.1 with 190.53 and 6.10.32

Are there any problems with this 1/18/2009 version?

thanks for looking.

Doesn't work.

I tested combination of Ubuntu 9.10 32-bit + CUDA SETI  and variants { NVIDIA 190.53 + CUDA libraries 2.3 } or { NVIDIA 185.18+ CUDA libs 2.2 } don't works for me. Yes, Einstein + 190.52 + 2.3 works.

I tried to test seti-cuda standalone and look into stderr.txt - there were many lines "Cuda error 'GaussFit_kernel' in file './cudaAcc_gaussfit.cu' in line 506 : invalid configuration argument." - ever stderr.txt size is greater than a megabytes. So, comparison of CUDA-crunched result to the CPU-crunched one showed no gaussians calculated for CUDA.

There is a bit newer seti cuda version at http://calbe.dw70.de/mb/viewtopic.php?f=9&t=116

Seti cuda doesn't work in 32bit, you'll need to convert your ubuntu to 64bit. In the link I've posted above for BeemerBiker, there is a 32bit client but is totally untested. I still advise you to go 64bit. If you also run astropulse, it is way faster in 64bit. For any problems post here in lunatics and we'll try to solve them.

I understood already. But how to do a conversion of working 32-bit Ubuntu into 64-bit version is still a mystery for me. By googling I saw only a suggestion for a clean reinstall. Is it a true? Gladly, I can do this because instead of md-raid1 (i can't push mdadm into glueless work, mirror always broken after artificially degraded raid-array due to physically disconnected one of two raid-harddrives) I'm using rsync everyday... Main question is: will this conversion help with enabling of CUDA-crunching with Crunch3r-made CUDA-app?

sunu:
Yes, a clean reinstall is the best option. Why do you need 32bit anyway? We're not in the '90s.  ;)

If you need to make a list of all installed packages, so you can reinstall them after the move, do:

dpkg --get-selections | grep -v deinstall > /home/...  (wherever you want to save it)

Then from synaptic you'll load this list and all packages will reinstall.
