Servers in Group 1 always work at high energy consumption, while servers in Group 2 may either work at high energy consumption or sleep at low energy consumption. An energy-efficient control policy determines the switch between work and sleep states of servers in Group 2 in a dynamic way. Since servers in Group 1 are always working with high priority to jobs, a transfer rule is prop","authors_text":"Jing-Yu Ma, Li Xia, Quan-Lin Li","cross_cats":["cs.SY"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2018-08-23T18:57:12Z","title":"Optimal Energy-Efficient Policies for Data Centers through Sensitivity-Based Optimization"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1808.07905","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":"sha256:692e78d418cc6f05c18f8e1a62eb7c05d2571dea7a5efc34ae6eec5e4711ba24","target":"record","created_at":"2026-05-18T00:07:23Z","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":"2b5d417abb9a60c1a6d70f6184527a807184174110aa26616a9cb22b8256f49f","cross_cats_sorted":["cs.SY"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2018-08-23T18:57:12Z","title_canon_sha256":"74510308be51dc9f98ac61031cdc9056e5f7e38d6df3f944eb9a30fbdfd5ea04"},"schema_version":"1.0","source":{"id":"1808.07905","kind":"arxiv","version":1}},"canonical_sha256":"8eac74a6a939a83d819ea222bb920181e8eff681c611d042a815114a40389916","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8eac74a6a939a83d819ea222bb920181e8eff681c611d042a815114a40389916","first_computed_at":"2026-05-18T00:07:23.042974Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:07:23.042974Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"MHlEibE4kJKyYKLNapdBbdYcCCy34p5dvVHC4pVlwwK6e5wbBDlEn7JQGUN/6BJNvnYCUch56qqUavxfqcTtCw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:07:23.043451Z","signed_message":"canonical_sha256_bytes"},"source_id":"1808.07905","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:692e78d418cc6f05c18f8e1a62eb7c05d2571dea7a5efc34ae6eec5e4711ba24","sha256:542bb2f8dc716dd09ec69c7e91868f4cfe2a646670d47847da5680964748c973"],"state_sha256":"716ac3b6626bc4c2afdcd71e889d9f6b6c63b8535ec5804aaa68915b8a1d1b9c"}
