Re: [gmx-users] Errors while building with Cuda 9.0

[Szilárd Páll]

Hi,

You really should update to 2016.4, but if you for som reason can not, you
can pass the target CUDA architectures to CMake;  see GMX_CUDA_TARGET_SM
documented here:
http://manual.gromacs.org/documentation/2016.4/install-guide/index.html#cuda-gpu-acceleration

Re: [gmx-users] Errors while building with Cuda 9.0

[Mark Abraham]

Hi,

CUDA 9 was not supported before GROMACS 2016.4, so you can either use a
newer GROMACS or an older CUDA.. Unfortunately, in that version, NVIDIA
removed support for older GPUs, which GROMACS supported with such
compilation flags.

[gmx-users] Errors while building with Cuda 9.0

[Kevin Chen]

Dear Gromacs Users,

I got the following error while building V2016.3 using CudaV9.0. Anybody has
a quick fix for it?


==
"nvcc fatal   : Unsupported gpu architecture 'compute_20'
nvcc fatal   : Unsupported gpu architecture 'compute_20'
CMake Error at
libgromacs_generated_nbnxn_cuda_data_mgmt.cu.o.Release.cmake:218 (message):"


==

Modules used for building:


=
Currently Loaded Modules:
  1) intel/17.0.4  3) cmake/3.7.1
  2) impi/17.0.34) cuda/9.0 (g)





Thanks in advance!

Kevin
