Hi Simon,

Yes, I'll try to reproduce my buggy case and send it over as soon as I can.

Cyril

Hi Cyril,
Although we don't use SART very much, there is a test that checks that we obtain what is expected, both with and without cuda:

(rtksarttest and rtksartcudatest).
Would you have a Shepp-Logan based test case for us?
Thanks,
Simon

Hi RTK users,

Has anyone used the CUDA version of SART ? I'm getting good results with the CPU version, and completely diverging results with the CUDA version (the results have attenuation values around 10^7 while they should be between 0 and 1).
I'm wondering if it's a problem on my side or a global issue.

Regards,
