Hi everybody,

I am trying to use recon-all with gpu. So I installed the CUDA librairies successfully (it seems). I am using freesurfer 5.0, cuda driver 3.2.

Here is the cudadetect output :

Detecting CUDA... There is 1 device supporting CUDA:

Device 0: "D13U" CUDA Driver Version: 3.20 CUDA Runtime Version: 3.20 CUDA Capability Major revision number: 2 CUDA Capability Minor revision number: 0 Total amount of global memory: 1341325312 bytes Number of multiprocessors: 15 Number of cores: 480 Total amount of constant memory: 65536 bytes Total amount of shared memory per block: 49152 bytes Total number of registers available per block: 32768 Warp size: 32 Maximum number of threads per block: 1024 Maximum sizes of each dimension of a block: 1024 x 1024 x 64 Maximum sizes of each dimension of a grid: 65535 x 65535 x 1 Maximum memory pitch: 2147483647 bytes Texture alignment: 512 bytes Clock rate: 1.46 GHz Concurrent copy and execution: Yes Run time limit on kernels: Yes Integrated: No Support host page-locked memory mapping: Yes Compute mode: Default (multiple host threads can use this device simultaneously)

But I get the already known error message with recon-all :

mri_em_register_cuda -skull nu.mgz /home/global//freesurfer//average/RB_all_withskull_2008-03-26.gca transforms/talairach_with_skull.lta

Acquiring CUDA device Using default device CUDA Error in file 'devicemanagement.cu' on line 46 : all CUDA-capable devices are busy or unavailable.

I rebooted my station but still get the same error. I'd like to know if there's something new about this issue ?

Kind regards,
