Webinar 4: Experiments in implementing the BigHPC Virtual Manager | 2nd BigHPC Webinar Series

After the success of the first webinar series, the UT Austin Portugal Program and the BigHPC consortium are back with a second round of webinars, running every two months from March 2022 to March 2023, called Towards a new generation of Big Data & HPC applications. This time around, experts from academia and industry will meet to look through some of the most relevant scientific and technological advancements made in response to the challenges we have dissected before.

Webinar 4: Experiments in implementing the BigHPC Virtual Manager

Virtual Manager (VM) is a component in the BigHPC implementation that aims to stage and execute application workloads optimally on one of a variety of HPC systems. It mainly consists of two subcomponents, ie. VM scheduler and VM repository.

The Virtual Manager Scheduler provides an interface to submit and monitor application workloads, coordinate the allocation of computing resources on the HPC systems, and optimally execute workloads by matching the workload resource requirements and QoS specified by the user with the available HPC clusters, partitions and QoS reported by the BigHPC Monitoring and Storage Manager components respectively.

Additionally, the Virtual Manager Repository provides a platform to construct and store the software services and applications that support BigHPC workloads as container images. It then provides those uploaded images in a programmatic way when a workload request is submitted to the Virtual Manager Scheduler for execution.

In this talk, we first a few possible approaches to designing Virtual Manager, then we discuss the pros and cons of each approach, and last we discuss the approach which we determined was most feasible and then adopted in the BigHPC implementation.

Important information about our training activities:
– Participation is free of charge. Kindly note, however, that to put on a course, we mobilize several people and incur expenses. Therefore, if you register for an event of ours, we expect you to attend it, for every time we assign a seat to someone we are preventing someone else from participating.
– Participants will be sent a link to the session 2 hours before the start time. If you do not receive it, please contact us at events@utaustinportugal.org
– Since our online courses are available globally, use a time zone converter to know what time the session is starting in your location.

The BigHPC Project is co-financed by the European Regional Development Fund through the Operational Program for Competitiveness and Internationalisation – COMPETE 2020, the Lisbon Portugal Regional Operational Program – Lisboa 2020 and the Portuguese Foundation for Science and Technology – FCT under UT Austin Portugal.
