# CU e-Science HTC-HPC Cluster and Cloud The CU e-Science cluster is a part of the National e-Science Infrastructure Consortium. Our cluster serves both CU and external users. Currently, we provide 1. **Slurm cluster**: Jobs can be run in interactive and batch modes. You can see examples of how to use the cluster in section SLURM. Currently, Centos 7 is the main operating system for both frontend and worker nodes. 2. **Kubernetes**: Online for CU users. ![CU e-Science cluster, MHMK Building, Faculty of Science, Chulalongkorn University](/files/2R1DuKNYuR63nfuJHD9K) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
