Neuromorphic computing promises an alternative architecture with improved energy efficiency for artificial intelligence. In this endeavor, code for the simulation of large-scale spiking networks on conventional supercomputers is the reference. We show that turning off automatic NUMA balancing may reduce energy consumption by 30%. This dwarfs other attempts of increasing the energy efficiency of a computing center with","authors_text":"Alp Inangu, Benedikt Steinbusch, Brian Wylie, Dennis Terhorst, Gorka Peraza Coppola, Guido Trensch, Hans Ekkehard Plesser, Jan Vogelsang, Markus Diesmann, Melissa Lober, Sebastian Gillessen, Susanne Kunkel","cross_cats":["q-bio.NC"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.DC","submitted_at":"2026-07-24T13:12:15Z","title":"NUMA balancing hampering performance of spiking network simulations"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.22275","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":"sha256:5929fbe7e8e1f7b6fc85813c26930e5f4d9c1c21b464b3dd47709fd75b49bbb2","target":"record","created_at":"2026-07-27T01:20:57Z","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":"85c60d533829e98cf190ccae096089e467b7ea1481b019fa15e616ca2255137a","cross_cats_sorted":["q-bio.NC"],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.DC","submitted_at":"2026-07-24T13:12:15Z","title_canon_sha256":"333ab54fba3b270603462fc4b31747d19047a1bf6f32f58591fbd497fbc0df67"},"schema_version":"1.0","source":{"id":"2607.22275","kind":"arxiv","version":1}},"canonical_sha256":"36266cb9ff680bdda09ba7214094883a14faddfe90706b217543d0250685136d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"36266cb9ff680bdda09ba7214094883a14faddfe90706b217543d0250685136d","first_computed_at":"2026-07-27T01:20:57.350051Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-27T01:20:57.350051Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"kgjnLmZngwgtbal3ZtD5rxrPCn+vh8Hzab9FoV2BX228igG1VpEXNzRlKRHsMJYOmrf28s3HrUGuLjkvQ3VCAw==","signature_status":"signed_v1","signed_at":"2026-07-27T01:20:57.350900Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.22275","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5929fbe7e8e1f7b6fc85813c26930e5f4d9c1c21b464b3dd47709fd75b49bbb2","sha256:b4c5a13ea70c4e9f05e52ff1cb27d456953cec9bc27a57470553be529dd18b83","sha256:69a88788abbc0b1e8a2aef4ecaf666c23809aab65545c8c3eaef364147556cf7"],"state_sha256":"ff2b5e0657a5d1ac38c2448acb92a7bba27e8bf78f458725957993449e5e9d79"}
