Workload from CERIT-SC system with generated Soft Walltimes

This workload comes from the 2022 paper "Improving Accuracy of Walltime Estimates in PBS Professional using Soft Walltimes" by Dalibor Klusáček and Václav Chlumský.
It contains two workloads. The first trace where the scheduler uses user-provided estimates is called CERIT-user-wall. It comprises 935,724 jobs executed in the system during January-August 2021 period. The second trace where soft walltimes are used is called CERIT-soft-wall. It covers 4 months since October 2021 and contains 351,853 jobs. Out of these, 254,663 jobs have recorded soft walltime. 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.

• CERIT-user-wall (only user-provided estimates provided) [download log].
• CERIT-soft-wall (both user-provided and generated soft walltimes) [download log].

Workload format used in this log is following (one Pod per line, separated by whitespaces):

jobID                      (Note: array jobs are denoted as, e.g., "16922[16921]", where "[16921]" denotes the parent job of the whole array job)
arrival time(epoch)
wait time(seconds)
runtime(seconds)
requested CPUs
Memory_Request(B)          (Note: Memory in Bytes, "," is used as decimal point)
user ID
queue name
requested walltime(seconds)
soft walltime(seconds)     (Note: "-1" denotes missing soft walltime)
