Cuda 9/10? #23

Closed thomasaarholt closed 4 years ago

thomasaarholt commented 5 years ago

The IT department is wanting researchers to play on their new GPU nodes, which consist of 28 CPU cores, 128 GiB RAM and 4 x NVIDIA RTX 2080 Ti cards, running Ubuntu 16.

For now they only have CUDA 9/10, with no SLURM/module loading system.

Is GCC a necessary requirement? GCC is available. Has anyone tried compiling with CUDA 9/10? Or am I best off contacting IT and asking them to install the necessary software? I will already need them to install CMake, for instance, so I will be contacting them nonetheless.

Last time I tried compiling the code using MATLAB(Mex), with CUDA toolkit 9 in Ubuntu system. There were a lot of lines where the compiler was trying to search for the CUDA toolkit 8. Hence, I had to change those search lines in the package. However, I always had compatibility issues. The package ran smoothly once I installed the toolkit 8. Although, I am not familiar with the CMAKE compiling procedure.

Sorry, CMake is not necessary for MULTEM - I just assumed.

Were you successful in running the code in the cluster? I too have some GPU hours and wanted to run this package in a cluster but after several attempts have been unable to do so.

If the Thrust library is not removed from MULTEM, the support for CUDA version over 9.2 always fails.

thomasaarholt commented 5 years ago

Could you clarify that?

ningustc commented 5 years ago

You can write a simple test using cuda9.2, include the thrust header files, and call the function raw_pointer_cast<>. In my package, I remove all the things related to thrust.
