The platform is a home-made Linux PC cluster, built with off-the-shelf components. At present this system constitutes of 64 nodes, with each node consisting of one Pentium 4 processor (1.6/2.0/2.5 GHz), one Gbyte of PC800/PC1066 RDRAM, one 40/80/120 Gbyte hard disk, and a network card. The computationally intensive parts of our program are written in SSE2 codes. The speed of this system is estimated to be 70 Gflops, and its price/performance is better than $1.0/Mflops for 64-bit (double precision) computations in q","authors_text":"Chao-Hsi Huang, Ting-Wai Chiu, Tsung-Ren Huang, Tung-Han Hsieh","cross_cats":["physics.comp-ph"],"headline":"","license":"","primary_cat":"hep-lat","submitted_at":"2002-08-22T18:17:21Z","title":"A Linux PC cluster for lattice QCD with exact chiral symmetry"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-lat/0208039","kind":"arxiv","version":2},"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":"sha256:87920f9b9ff169e30df442d9eda15c9e15b226fb5dcfe970508460bb266a5d27","target":"record","created_at":"2026-05-18T04:28:37Z","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":"38c05c829a1c2e9822d3bab0df14b7cd1ddd46a2e13a0b6bea38f6b92ad3db04","cross_cats_sorted":["physics.comp-ph"],"license":"","primary_cat":"hep-lat","submitted_at":"2002-08-22T18:17:21Z","title_canon_sha256":"0ed92f6a7072ab151071f90d32f4ebf77156b5beac94d10d2e4193fd6457e7cd"},"schema_version":"1.0","source":{"id":"hep-lat/0208039","kind":"arxiv","version":2}},"canonical_sha256":"70aa6622ab7e959ef4af75bfee5db43b66d12c2f26c97888210525bf9ec6baa3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"70aa6622ab7e959ef4af75bfee5db43b66d12c2f26c97888210525bf9ec6baa3","first_computed_at":"2026-05-18T04:28:37.869579Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:28:37.869579Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"XOj/QC5sKIHY/KvPeqfK8ccIOGiVqOhSW18wI4wVpqFZmScJWxi6/FFYjOg7dJt3w5sS4YHgzeis00Yr2Lr5AA==","signature_status":"signed_v1","signed_at":"2026-05-18T04:28:37.870009Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-lat/0208039","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:87920f9b9ff169e30df442d9eda15c9e15b226fb5dcfe970508460bb266a5d27","sha256:cdd01f2de10a7c6e660a5c583fa64d5c71428e3125d8afb853d928e722a80717"],"state_sha256":"7783348148ef45f8670e342775e481a9ad9fb0cf33e6593cc32fb73265e990dd"}
