Hi:
Any solution for the 32 bit version ?...

CUDA users,
The problem with the _cuda binaries (message: CUDA Error in file 'devicemanagement.cu'...) has been fixed, and new binaries are available for download from here:
ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/misc/linux-centos4_x86_64/
download the file 'fscudabins-linux-centos4_x86_64.tgz' and extract it (tar zxvf <filename>) into your $FREESURFER_HOME/bin directory. This is for the 64b linux platform only (centos 4 and 5).
fyi, the problem was that the utility UPX, which is run on the publicly distributed freesurfer binaries to reduce their size, seemed to cause this strange problem.
Let us know how these utilities work. In particular we'd like to get a sense of the type of NVIDIA GPU cards people are using.

i've just posted the file 'fscudabins-linux-centos4.tgz' here:
ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/misc/linux-centos4/
note that we have recently discovered a new problem with running mri_em_register_cuda on brains with skull: the results are off compared to the cpu version. so updates to that will be available next week sometime.

Hi Nick:
I uncompress fscudabins-linux-centos4.tgz, but I continue to get the error:
"mri_em_register_cuda -skull nu.mgz /usr/local/freesurfer/average/RB_all_withskull_2008-03-26.gca transforms/talairach_with_skull.lta

recon-all -s ingrid_2 exited with ERRORS at Fri Aug 20 21:48:43 CLT 2010"
Could you please tell me how can I correct the problem ?...

Hi Nick (and others),
do you already have positive experience with ATI cards, too? We think about buying a new workstation with lots of GPU power so it would be great help to know what really pays off: GeForce GTX 480 or ATI Radeon HD 5870? Or should we go for Nvidia Tesla? What kind of tech specs are important here? Double or single precision floating point performance, number of cores, amount of memory...
Thanks and cheers, Georg
CUDA won't work on ATI.

Yes, I know, but will Freesurfer support ATI Stream and maybe OpenCL in the near future? OpenCL should be something that could run both on ATI and Nvidia GPUs.
And then again, is it a good idea to invest money in Nvidia Tesla cards?
Cheers,
Georg

Hi
I'm not sure if or when FS will have OpenCL support. Notice that not all recon-all steps are GPU ready yet.
I wouldn't invest now in Tesla platform. Try the 280 or 480 model instead.

we do not plan to support ATI or OpenCL in the near future (not likely in 2010). we decided to stick with CUDA for now because its a much more mature development platform compared to OpenCL.

we're still trying to find the 'lowest common denominator' card to support, as clearly have more memory and double precision support allows more efficiency options in development. currently we target the Quadro FX4800, which is about the same as the GTX 285, as the LCD card, but we test and develop on a C1060 and C2050 as well. a tesla card is useful if you plan to process multiple subjects on one processor (assuming you have a multicpu with tons of memory) and you want to have a gpu per processor. otherwise, for our current gpu stream, a tesla is overkill.

Hi Nick,
We are planning to buy a GTX 460 1G card because of the cuda support of Freesurfer. It seems the most reasonable buy for CUDA device, 336 Core, 1350MHZ shader, and around 100 $ cheaper than the 285GTX. Does this card has double precision support? And what is you guess (time) about the stable CUDA support for let's say 50-70% of freesurfer stream?
Thanx,
Gergo
