Hi,
I'm attempting to run
c:\PyFR-1.7.5\examples\euler_vortex_2d>mpiexec -n 2 pyfr run -b cuda -p
euler_vortex_2d.pyfrm euler_vortex_2d.ini
with the change in .ini file from
device-id = round-robin
to
device-id = local-rank
.
I get
pycuda.driver.CompileError: nvcc compilation of
C:\Users\admin\AppData\Local\Temp\tmpinwerlob\kernel.cu failed
[command: nvcc --cubin -arch sm_20 -m64
-Ic:\users\admin\appdata\local\programs\python\python36\lib\site-packages\pycuda\cuda
kernel.cu]
[stdout:
nvcc fatal : Value 'sm_20' is not defined for option 'gpu-architecture'
]
.
My understanding (from googling the error) is that sm_20 can not be used
with cuda 9. I don't know how (or where) to change this flag to sm_30 which
should work(?). (I've tried to set the enviroment variable CUDA_NVCC_FLAGS
"-arch=sm_30, but it makes no difference. I still get Value 'sm_20' is not
defined for option 'gpu-architecture')
I guess changing from sm_20 to sm_30 (or something) is what I want to do?
Can anyone help me with how to do that?
Running on Windows 10, cuda 9.1 with a 1080 ti (and a gtx 470).
I'm attaching the complete output I get from running the program.
Best regards,
Magnus
