Hello FreeSurfer Developers,

I would like to use recon-all with the option "-use-gpu" so I ran cudadetect first to see whether the nvidia card on my system will be detected. But at least the values for total amount of memory and number of cores are wrong (should be 8GB and 2304 cores).

$ cudadetect Detecting CUDA... There are 0 devices supporting CUDA:

Device 0: "Quadro K5200" CUDA Driver Version: 8.0 CUDA Runtime Version: 6.50 CUDA Capability Major revision number: 3 CUDA Capability Minor revision number: 5 Total amount of global memory: 4224450560 bytes Number of multiprocessors: 12 Number of cores: -2109039396 Total amount of constant memory: 65536 bytes Total amount of shared memory per block: 49152 bytes Total number of registers available per block: 65536 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: 2147483647 x 65535 x 65535 Maximum memory pitch: 2147483647 bytes Texture alignment: 512 bytes Clock rate: 0.77 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) $

What could I try?

Thank you.
