Convolution self test fail

[tobiHZDR]

Compiling the master branch with CUDA 8.0 leads to a fail of the Convolution self test. On my system the bug arises in the testConvolution function. Outputting the Bsat from copypadmul2.cu gives wrong results in the case of the convolution self test. It seems like that the ToMSlice function produces the error. I also checked for the normal Demag calculation. There everything seems to be ok.

I used the standard problem for the test:
mumax3 -paranoid test/standardproblem4.mx3

Output from copypadmul2.cu
Bsat= 1.256637e-06 Ms= 2.338954e-313 Ms_mul= 1.000000e+00

And therefore,
convolution self-test tolerance: 0.37432534 FAIL

Can anyone reproduce this problem?

Best Regards,

@tobiHZDR I confirm the behavior with CUDA 8. Have you tried other CUDA versions?

[tobiHZDR]

@godsic I didn't try other CUDA versions. But today I can test CUDA 7.5

Edit: The problem also occurs using CUDA 7.5

Bug still persists in CUDA 12.6.
