===== Abstract =====

Despite HPC is the base of many research projects involving numerical simulations, generally its scope within education of the applied disciplines
needs improvement. 
We bring together I/O experts from data centres, users and application workflows to share current practices for parallel I/O and storage with application to scientific workflows, issues, and obstacles for both hardware and the software stack, and R&D to overcome these issues.
The meeting series fills this gap by providing a forum to experts, students and the interested public with presentations from external guests
about HPC storage systems. This also facilitates discussions with the goal to train essential skills for research in HPC. The event takes place every
month both during winter and summer semesters regardless of lecture free time. 

Our regular meetings typically revolve around a selected topic, have at least one invited speaker, provides opportunity for discussion (>= 15 min) regarding this topic and an open discussion at the end. We decide about some upcoming topic and an initial speaker.

It is supported by the NHR and GWDG. 
Powered by VI4IO, the HPC IODC workshop, and the MCSE, DECICE and KISSKI projects.

====== Participation ======

Attendance is free of charge.

We send the regular invitation to the [[https://listserv.gwdg.de/mailman/listinfo/mst/|Mailing list]].

Please note that we plan to record special sessions with the intent of providing the recordings
via BBB to other students but also to publish and link the recordings on YouTube for future terms.
If you appear in any of the recordings via voice, camera or screen share, we need your consent to publish the recordings.
