Minimising carbon associated with computing will require compromise. In this presentation I will present the results from simulating a Grid site where the compute is run at reduced frequency when the predicted carbon intensity rises above some threshold. The compromise is a reduction in throughput in exchange for an increased carbon-efficiency for the work that is completed. The presentation...

In order to achieve the higher performance year on year required by the 2030s for future LHC up- grades at a sustainable carbon cost to the environment, it is essential to start with accurate measurements of the state of play. Whilst there have been a number of studies of the carbon cost of compute for WLCG workloads published, rather less has been said on the topic of storage, both nearline...

Data center sustainability, a phenomenon that has grown in focus due to the continuing evolution of Artificial intelligence (AI)/High Performance Computing (HPC) systems; furthermore, the rampant increase in carbon emissions resulted in an unprecedented rise in Thermal Design Power (TDP) of the computer chips at the Scientific Data and Computing Center (SDCC) at Brookhaven National Laboratory...

The Smart Procurement Utility is a tool that allows the visualisation of HEPScore/Watt vs HEPScore/unit-cost to guide procurement choices and the compromise between cost and carbon. It uses existing benchmarking data and allows the entry of new benchmarking data. Costs can be entered as relative numbers (percentages relative to a chosen baseline) to generate the cost-related plots.

I will present some preliminary studies and ideas to understand natural job drainage and power reduction in PIC Tier-1, which is using HTCondor. Based on the historical batch system logs, we are simulating natural drainage and understanding how we can modulate the PIC farm without killing jobs.
