In this online PRACE/SNIC workshop hosted by NSC, including seminars and hands-on sessions, we will consider how to run the [https://www.vasp.at/ Vienna Ab-initio Simulation Package (VASP)] efficiently on supercomputers. The workshop is mostly suitable for beginners and the focus will be on best practices for running VASP calculations. The hands-on part will be done at the Tetralith cluster, NSC, LiU. Parts of the presentations (to be made available for download) can also be of interest for advanced users.

Time: Tuesday 22nd February 10:00 - 17:00 and Wednesday 23rd February 10:00 - 17:00

An online training event suitable for new users of the WIEN2k software package. The first part includes a brief overview and background for using WIEN2k. Thereafter, practical examples and discussion of running WIEN2k efficiently on the NSC clusters will be made. The last part of the event will be open for hands-on testing and questions. Note that for the hands-on part you need to be covered by a WIEN2k license and have an account and compute project at NSC.

Registration is not necessary, though if interested to join, I encourage you to contact me beforehand to describe your topics of interest, or if you have some other questions: weiol@nsc.liu.se

Time: 18 Nov 2021, 13:00 - ends at latest 17:00.

|location=Linköping (NSC)
|start date=2021-04-20
|end date=2021-04-20
}}

== Overview ==
The NSC SNIC/PRACE webinar will present useful tools and best practices for working effectively on HPC systems. This will among other things cover methods and skills to help you use allocated resources effectively. It is expected to be of interest for a general HPC system user, both at a more familiar (intermediate) or starting (beginner) level.

While the main part of the content and practices will be useful for HPC systems in general, we will also present examples and special tools specific for the NSC clusters, e.g. Tetralith and Sigma.

'''Time''': Tue 2021-04-20, two parts: 10-12, 13-15

'''Place''': Zoom link will be sent to registered participants

== Topics ==
* Tools at your end (e.g. terminal, ssh config., file transfer tools, VNC)
* HPC system anatomy (login and compute nodes, interconnect, storage)
* Properties and features of storage areas (e.g. quotas, performance, locality, backups, snapshots, scratch)
* Concept of parallelism (Amdahl’s law), scalability, scheduling and practical advice for good performance
* Software on an HPC system (OS, modules, python envs., concept of build envs., containers with Singularity)
* Ideas and strategies for organizing your workflow (data and file management, traceability and reproducibility)
* Interacting with the Slurm queueing system (requesting resources interactively or in batch)
* Practical examples (preparing, submitting, monitoring and evaluating job efficiency)
