This workshop presents an overview of HPC at RUC, where we introduce different types of HPC. Our main focus is on HPC Type 1 - Interactive also known as UCloud. The slides from the presentation are available under the following link: https://dirac.ruc.dk/~jklust/HPC/RUC_eScience_HPC_UCloud.pdf

The agenda of the workshop has the following points:

1. Presentation of RUC's eScience portal and DeiC HPC infrastructure
   1. Learning about SLURM scheduler for DeiC Type 2 and LUMI: http://slurmlearning.deic.dk/
   2. Knowledge pool maintained by DeiC: https://deic-hpc.github.io/EuroCC-knowledgepool/ or https://deic.dk/en/Supercomputing/Instructions-and-Guides
2. Interactive part starting with login in the UCloud: https://cloud.sdu.dk additionally you can read about UCloud on https://interactivehpc.dk
   1. Explore main page and documentation: https://docs.cloud.sdu.dk
   2. Upload of data (possibility to edit data in the cloud from Files and right click - open with...)
      1. web (drag and drop up to 5GB files)
      2. syncthing (P2P service allowing synchronization of data between UCloud and other devices)
      3. minio
   3. Describe of available applications (optimized and ready to be used out of box)
      1. Application types: https://docs.cloud.sdu.dk/Apps/type.html
         1. Virtual Desktop: https://docs.cloud.sdu.dk/Apps/vde_apps.html
         2. Interactive Computing: Open Interface https://docs.cloud.sdu.dk/Apps/interactive_apps.html
         3. Virtual Machine: https://docs.cloud.sdu.dk/Apps/vm_apps.html
      2. Use Cases: https://docs.cloud.sdu.dk/hands-on/use-cases.html
   4. Run selected application as a job
      1. jupyterlab (Python, R, Julia)
      1. install new packages
         
      2. illustrative examples for Natural Language Processing (NLP)
      • wordcloud --- stylecloud --- https://github.com/minimaxir/stylecloud
      • pip install stylecloud
      • import
      • stylecloudstylecloud.gen_stylecloud(file_path='text_stored_on_ucloud.txt')
   5. Optimization of tasks with scriptable workflow
      
   1. initiate environment - dependency option - scripting of tasks
      
   2. batch processing (similarly to HPC Type 2, where job gets scheduled and terminates as soon as the script finishes)
      
   6. Download processed data
