HOWTO: Use GPU with Tensorflow and PyTorch
GPU Usage on Tensorflow
Environment Setup
To begin, you need to first create and new conda environment or use an already existing one. See HOWTO: Create Python Environment for more details. In this example we are using python/3.6-conda5.2
Once you have a conda environment created and activated we will now install tensorflow-gpu into the environment (In this example we will be using version 2.4.1 of tensorflow-gpu:
conda install tensorflow-gpu=2.4.1
STAR-CCM+ 18.04.008 (v2306) available on Owens
Date:
Monday, July 31, 2023 - 6:00pm
System(s):
STAR-CCM+ 18.04.008 (v2306) is available on Owens. Mixed precision is also available. Use module load starccm/18.04.008 and module load starccm/18.04.008-mixed , respectively.
HOWTO: Run Python in Parallel
We can improve performace of python calculation by running python in parallel. In this turtorial we will be making use of the multithreading library to run python code in parallel.
HOWTO: Use GPU in Python
If you plan on using GPUs in tensorflow or pytorch see HOWTO: Use GPU with Tensorflow and PyTorch
This is an exmaple to utilize a GPU to improve performace in our python computations. We will make use of the Numba python library. Numba provides numerious tools to improve perfromace of your python code including GPU support.
System Downtime August 8 2023
A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, August 8, 2023. The downtime will affect the Pitzer, Owens and Ascend Clusters, web portals, and HPC file servers. MyOSC and state-wide licenses will be available during the downtime. See this link for more details: https://www.osc.edu/calendar/events/2023_08_08-system_downtime_august_8_2023
Gromacs 2023.2 is available
Gromacs 2023.2 has been installed on all the clusters. Usage is via the module gromacs/2023.2. For help loading an installation, use the command: "module spider gromacs/2023.2". That command also emits information on usage and installation details.
PETSc 3.19.3 is available on Owens and Pitzer
PETSc 3.19.3 has been installed with both gnu and intel compilers on both Owens and Pitzer. Usage is via the module petsc/3.19.3. For help loading, use the command: "module spider petsc/3.19.3". That command also emits information on usage and installation details.
Tinker 8.10.5 is available on Owens and Pitzer
Tinker 8.10.5 has been installed with intel/2021.3.0 compilers on Owens and Pitzer. Usage is via the module tinker/8.10.5. For help loading, use the command: "module spider tinker/8.10.5". That command also emits information on usage and installation details.
Mathematica
Mathematica is a mathematical computation program. It is capable in many areas of technical computing including but not limited to neural networks, machine learning, image processing, geometry, data science and visualizations.
