CUDA™ is a parallel computing platform and programming model invented by NVIDIA. It enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU). With millions of CUDA-enabled GPUs sold to date, software developers, scientists and researchers are finding broad-ranging uses for GPU computing with CUDA.

For CUDA development please load the "cuda" module.  Doing so will ensure that your environment is set up correctly for the use of the CUDA compiler, header files, and libraries. The cuda versions below are currently supported on hipergator.

In order to gain interactive access to a GPU server you should run similar to the one that follows.

        cuda/11.0.207

        cuda/11.1.0

  For detailed information about a specific "cuda" module (including how to load the modules) use the module full name.

  For example:
  
−
To gain access to one of the Fermi-class GPUs, you can make a similar request but specify the "fermi" attribute in your resource request as below.
+
    $ module spider cuda/10.0.130
 +
--------------------------------------------------------------------------------------------------------------------
  
−
<pre>
+
$ module load cuda/10.0.130
−
qsub -I -l nodes=1:gpus=1:fermi,walltime=01:00:00 -q gpu
 
−
</pre>
 
  
−
If a gpu is available, you will get a prompt on one of the nodes within a minute or two.  Otherwise, you will have to wait or try another time.  If you choose to wait, you will be connected when a gpu is available.    The default walltime limit for the gpu queue is 10 minutes. You should request the amount of time you need but be sure to log out and end your session when you are finished so that the GPU will be available to others.

$ which nvcc

If your work needs both GPUs attached to the same node, you would run the following command instead.

$ printenv | grep CUDA

===Selecting CUDA Arch Flags===

When compiling with NVCC, you need to specify the Nvidia architecture that the CUDA files will be compiled for. Please refer to [https://docs.nvidia.com/cuda/cuda-compiler-driver-nvcc/index.html#gpu-feature-list GPU Feature List] for CUDA naming scheme sm_xy where x denotes the GPU generation and y denotes the version. The table below lists the SM flags for the three types of GPUs on HiPerGator.

If you need to request a particular machine, say ''tesla1'', you would use the following qsub command.

Description

cuda website  
CUDA™ is a parallel computing platform and programming model invented by NVIDIA. It enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU). With millions of CUDA-enabled GPUs sold to date, software developers, scientists and researchers are finding broad-ranging uses for GPU computing with CUDA.

Environment Modules

Use the 'module avail' command after loading a cuda environment module to see the available module trees or see which compiler and openmpi modules require the cuda module to be loaded.

System Variables

  • HPC_CUDA_DIR
  • HPC_CUDA_BIN
  • HPC_CUDA_INC
  • HPC_CUDA_LIB

Program Development

Environment

For CUDA development please load the "cuda" module. Doing so will ensure that your environment is set up correctly for the use of the CUDA compiler, header files, and libraries. The cuda versions below are currently supported on hipergator.

  For detailed information about a specific "cuda" module (including how to load the modules) use the module full name.
  For example:

     $ module spider cuda/10.0.130

$ module load cuda/10.0.130

$ which nvcc

Selecting CUDA Arch Flags

When compiling with NVCC, you need to specify the Nvidia architecture that the CUDA files will be compiled for. Please refer to GPU Feature List for CUDA naming scheme sm_xy where x denotes the GPU generation and y denotes the version. The table below lists the SM flags for the three types of GPUs on HiPerGator.
