OpenOnDemand - OOD
The new GRIT Open OnDemand HPC portal (https://hpc.grit.ucsb.edu), is designed to significantly enhance your computational experience.
This web portal provides a range of powerful utilities, including dedicated interfaces for Jupyter Notebook, R Studio, and VS Code Server. It also offers an on-demand desktop environment equipped with applications such as ENVI, PyCharm, and Positron. For advanced users, direct shell access is available. The HPC Portal also provides customizable options for CPU and GPU selection for demanding computational tasks. To ensure fair resource allocation and prevent system monopolization, all jobs are submitted via a Slurm scheduler.
