Drop the compute_11 from the compile line, as I think CUDA 7.5 dropped
support for the oldest stuff NVIDIA made. Its a bit hard to find
(arch/Linux-x86_64.cuda), but that is where the cuda generation code is.
Here for instance, are the contents of my file, which works for me with
CUDALIB=-L$(CUDADIR)/lib64 -lcudart_static -lrt
CUDA=$(CUDAFLAGS) -I. $(CUDAINCL)
CUDACC=$(CUDADIR)/bin/nvcc -O3 --maxrregcount 32 $(CUDAGENCODE)
-Xcompiler "-m64" $(CUDA)
*CUDAGENCODE= -gencode arch=compute_35,code=sm_35 -gencode
arch=compute_35,code=compute_35 -gencode arch=compute_50,code=sm_50
*I've bolded the big change I had to make from the stock sources, which
should in theory be suitable for your machine too. Is there a particular
reason you are trying to compile NAMD 2.9 now? 2.11 is out and is awesomer!
