Kubernetes Workload from CERIT-SC system

This workload comes from the 2022 paper "Using Kubernetes in Academic Environment: Problems and Approaches" by Viktoria Spišaková, Dalibor Klusáček and Lukáš Hejtmánek.
It contains real life-based descriptions of 292,238 Pods executed in CERIT-SC infrastructure during July 2021 - June 2022 period (CERIT-SC Kubernetes Platform Documentation). Detailed description of the workload can be found in the aforementioned paper.
The workload is stored in SWF-like format with the description available in the workload header.
