Hi Steve,

There are two ways around this:

  1. Update CUDA/your driver to correspond to be greater than or equal to the CUDA/driver version NAMD was compiled against. CUDA 10.0 is from a few years ago, and the driver may just be too old.
  2. Compile NAMD yourself with your existing CUDA installation. NAMD requires CUDA 9.1 according to the release notes, so you are good there.

Subject: namd-l: NAMD CUDA

I have down loaded the binary cuda version of NAMD, NAMD_2.14_x86_64-multicore-CUDA onto my Ubuntu (16.04) machine. Using the “nvidia-smi”, I found my GPU card Quadro P5000, NIVIDIA-SMI 415.27, Driver Version: 415.27 and the CUDA vesion 10.0.

When I attempt to run namd2 get the following: “CUDA driver version is insufficient for CUDA runtime version”…I’m a novice at this, but, is this a barrier that cannot be overcome?

Thanks, Steve
