what is the compatiable CUDA toolkit and driver for the latest LAMMPS gpu package?

Dear LAMMPS Users and Developers,

I am using CUDA toolkit (version 4.1) and my nvidia driver is of version 295.33. The intel compiler version 2011_sp1update2 was used. The compilation for lammps was smooth. But, when I run lmp, I got the error information, “GPU library not compiled for this accelerator”.

Any suggestion for this error? And what is the compatiable CUDA toolkit and driver for the latest LAMMPS gpu package? Thanks a million for your time.

Hi

I think the problem is that you compiled for a wrong architecture. Probably you got a Compute 1.3 GPU and compiled for 2.0 (aka Fermi Level).
You just have to edid that part in the Makefile.

Cheers

christian already answered your question about the error message.
i have successfully tested the GPU package with CUDA 3.2, 4.0,
and 4.1 and 1.3, 2.0, and 2.1 hardware and also with OpenCL on
Nvidia (best to use the libraries/driver that comes with CUDA 4.1)
and AMD hardware (use SDK 2.5 and up).

HTH,

I appreciate your reply. The issue was shotted on hardware. One of four graphics cards is 1.3 GPU and I compiled the gpu package with -arch=sm_2.0. I uninstalled the old card and all issues were fixed! That is a big help. Thanks again.
