But these geo-distributed data centers (GDDCs) have a significant associated environmental impact due to their increasing carbon emissions and water usage, which needs to be curtailed. Moreover, the energy costs of operating these data centers continue to rise. This paper proposes a novel framework to co-optimize carbon emissions, water footprint, and energy costs of GDDCs, using a hybrid workload management framework called SHIELD that integrates machine learning guided local search with a decompo","authors_text":"Cullen Bash, Dejan Milojicic, Sirui Qi, Sudeep Pasricha","cross_cats":["cs.LG","cs.NE"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.DC","submitted_at":"2023-08-24T21:11:55Z","title":"SHIELD: Sustainable Hybrid Evolutionary Learning Framework for Carbon, Wastewater, and Energy-Aware Data Center Management"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2308.13086","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:c87c37f9d436fd92f5d51ed8a9cb8d53b0610d6cf1c5d1e95c9dab709b9a9107","target":"record","created_at":"2026-07-05T06:44:38Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"c87698d0fc0e7cc68ed5d7a6d904aff470f4b1f860483cd615eee0ca6dec4245","cross_cats_sorted":["cs.LG","cs.NE"],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.DC","submitted_at":"2023-08-24T21:11:55Z","title_canon_sha256":"5cb741d8793e3ef79c8997e59bcc79101d0d58f78ecf7e47dd1a2ea5c3b75fde"},"schema_version":"1.0","source":{"id":"2308.13086","kind":"arxiv","version":1}},"canonical_sha256":"83ce67e453cfd7a83b2483b1f911a9780f0f35e96959c4f96f8abb7fa8e3697b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"83ce67e453cfd7a83b2483b1f911a9780f0f35e96959c4f96f8abb7fa8e3697b","first_computed_at":"2026-07-05T06:44:38.399784Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:44:38.399784Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"sx11P187auLbtiFqO4TmaEKZVVO45G5MjFAzuahYFbArGhbRG7hycZoj85GQJBjfMkLl7iaz1Z2hbRQU5L7HCg==","signature_status":"signed_v1","signed_at":"2026-07-05T06:44:38.400358Z","signed_message":"canonical_sha256_bytes"},"source_id":"2308.13086","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c87c37f9d436fd92f5d51ed8a9cb8d53b0610d6cf1c5d1e95c9dab709b9a9107","sha256:eaba3780b5be531a1855a8ed916c46ce041383190b7151bc0e9bf103371e9fc5"],"state_sha256":"c760ee1794ddcab14fecef9a14f02676d33fc00e1fdfba713bcaefe1675b3002"}
