I need a hashtable on the host

Accelerated Computing CUDA CUDA Programming and Performance

I am writing some code to solve support vector machines and I am handling some “cache” on the host of the kernel matrix.

When I try to compile using nvcc and include the <tr1/unordered_map> I get an cfee++ error.

I thought it was possible to compile the kernel using nvcc and then use gcc to compile the rest of the code, but I think the gcc on the server I am using is too old. I have no admin control of the server. What options do I have to use a hast table?

nvcc and gcc versions:

-bash-3.2$ nvcc --version

I think it will be impossible to do that if you are using Windows-based NVCC, whose name mangling is different from that of GCC.

If you are using Linux-based NVCC, just compile the kernel using NVCC, compile the other modules using GCC, and then link all objects using NVCC.
