During the July 18th maintenance, RC engineers installed a new /scratch file storage system on Rivanna. We have created sample scripts and instructions to help you transfer your files from the previous file system to the new one.(Expand the link below for details.) The previous scratch filesystem, now called /oldscratch, will be permanently retired on October 17, 2023 and all the data it contains will be deleted.
Users should clean up their /oldscratch directory in preparation, to minimize the load. A sample script is posted below.
Modified queue limits have been implemented to provide maximum read/write performance of the new /scratch filesystem.

Rivanna will be down for maintenance on July 18, 2023 beginning at 6 a.m. You may continue to submit jobs until the maintenance period begins, but if the system determines your job will not have time to finish, it will not start until Rivanna is returned to service.
All systems are expected to return to service by 6 a.m. on Wednesday, July 19.
IMPORTANT MAINTENANCE NOTES New scratch RC engineers will be installing a new /scratch storage filesystem that can be accessed at /scratch/$USER after the end of maintenance.
Modified queue limits will be implemented to provide maximum read/write performance of the new /scratch filesystem.

Rivanna will be down for maintenance on May 30, 2023 beginning at 6 a.m. You may continue to submit jobs until the maintenance period begins, but if the system determines your job will not have time to finish, it will not start until Rivanna is returned to service.
All systems are expected to return to service by 6 a.m. on Wednesday, May 31.
IMPORTANT MAINTENANCE NOTES Five RTX3090 nodes (4 GPU devices each) have been added to the gpu partition - use --gres=gpu:rtx3090 in Slurm script.
Modules The toolchains gompic gcccuda goolfc will be removed from Rivanna during the maintenance period, since we now have CUDA-aware toolchains based on gcc/11.

Medical images come from multiple sources such as MRI, CT, X-ray, ultrasound, and PET. Analysis of these images requires a comprehensive environment for data access, visualization, processing, and algorithm development. The main challenge is to extract clinically meaningful information based on advanced techniques such as Artificial Intelligence (AI). To achieve this, one needs to clean, segment, register, and label a large collection of images. For the AI analysis, there are many more challenges such as iteratively adjusting AI models or learning parameters. MATLAB provides tools such as Medical Imaging Toolbox and Deep Learning Toolbox and algorithms for end-to-end medical image analysis and AI workflow.

Rivanna has included Intel KNL (Knight’s Landing) nodes for several
years. This was a unique architecture, not well suited for general
use, and the manufacturer has stopped producing or supporting this type
of hardware. As a result, the KNL nodes will be removed from Rivanna
on June 30, 2022.
