The $k$-mer counting problem is to build a histogram of all substrings of length $k$ in a given genome sequence. We present the open source $k$-mer counting software Gerbil that has been designed for the efficient counting of $k$-mers for $k\\geq32$. Given the technology trend towards long reads of next-generation sequencers, support for large $k$ becomes increasingly important. While existing $k$-mer counting tools suffer from excessive memory resource consumption or degrading performance for large $k$, Gerbil is abl","authors_text":"Marius Erbert, Matthias M\\\"uller-Hannemann, Steffen Rechner","cross_cats":["q-bio.QM"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2016-07-22T09:48:53Z","title":"Gerbil: A Fast and Memory-Efficient $k$-mer Counter with GPU-Support"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1607.06618","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":"sha256:6f6d64b2eb9df20bba8400d9c068f9aacb953dbe3a842ffbfb5ed60114635fad","target":"record","created_at":"2026-05-18T01:10:39Z","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":"9fed2a8bc248afdd098adb20d1758fc16be564bae93ce0673696634a5f1cf1c5","cross_cats_sorted":["q-bio.QM"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2016-07-22T09:48:53Z","title_canon_sha256":"638e12f3aef4f0b975e14c83ef45ee0975c5d3bfb152c7fec39e98bb3b3ace37"},"schema_version":"1.0","source":{"id":"1607.06618","kind":"arxiv","version":1}},"canonical_sha256":"d34f873c9fde42821397534c3a9436488165815e8fb74cbb597afd825532a53e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d34f873c9fde42821397534c3a9436488165815e8fb74cbb597afd825532a53e","first_computed_at":"2026-05-18T01:10:39.442498Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:10:39.442498Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"4V61BDWuni+qMd4yTLaSNg+Cl2IhIO3SiA0zJi34kLxNFXZ/ggSuZKbhpAQxNV7rMdL8aMVIewhVk6bI4cMjAA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:10:39.443007Z","signed_message":"canonical_sha256_bytes"},"source_id":"1607.06618","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6f6d64b2eb9df20bba8400d9c068f9aacb953dbe3a842ffbfb5ed60114635fad","sha256:1628ae584fa513c7f6f131066143af74320ca8ba7684e518d4efb8c8dfb6942c"],"state_sha256":"ad2263fa8a42f760d17ea694b7e39ce7d9343df723afe382f9ce2dc664d4e990"}
