age author description
Tue, 07 Oct 2008 21:03:26 +0000 mas01mc unionized punning of the sbucket.snext field into {subucket* ptr, unsigned numBuckets}snext; so that list-head code is 64-bit friendly.
Tue, 07 Oct 2008 20:08:22 +0000 mas01mc added portable C++ reinterpret_cast<Uns32T> instead of C-style cast to fix 64-bit compile error in query.cpp. This is in advance of re-writing bucket class to include a union{} of pointer and counter fields.
Wed, 10 Sep 2008 18:55:16 +0000 mas01mc Added LSH_CORE_ARRAY structure for hashtables instead of linked lists. Maintained Backwards Compatibiliity with indexes build for linked list format. Added tests for indexing and merging. Tested backwards compatibility OK.\n\n The purpose of the LSH_CORE_ARRAY data structure is greater space efficiency and L1/2 cache usage. Essential for multiple indexes with multiple hashtables in RAM
Fri, 05 Sep 2008 14:16:21 +0000 mas01mc converted read/write into fread/fwrite for LSH hashtable serialize and unserialize. INDEXING is now faster.
Tue, 19 Aug 2008 14:27:21 +0000 mas01mc Adding large_adb support (up to 1M tracks) large_adb
Thu, 07 Aug 2008 17:05:22 +0000 mas01mc Fixed persistent index bug where indexName identifier was an un protected string pointer rather than a copy of the string. Hence the index name was getting deleted and the test for persistent index was failing.
Thu, 07 Aug 2008 01:53:38 +0000 mas01mc Added server-side loading of persistent index (LSH hashtables) via --load_index -d dbName -R radius -l sequenceLength. Queries using these parameters will lookup the memory-resident hashtable instead of loading one from disk.
Tue, 05 Aug 2008 22:40:38 +0000 mas01mc changed FORMAT2 index serialization so that token bits don't scribble over point index for >=32768 tracks
Fri, 01 Aug 2008 15:45:10 +0000 mas01mc fixed recently-introduced strict point ordering bug when LSH index is initially empty
Fri, 01 Aug 2008 15:04:31 +0000 mas01mc fixed file size allocation for FORMAT2 files. Made LSH index size() in bytes an unsigned long long. Changed the name of lsh_inCore flag to lsh_on_disk (to reverse the sense of the 'flag').
Wed, 30 Jul 2008 18:00:50 +0000 mas01mc fixed UNIT_TEST_LSH.cpp to work with refactored lshlib and fixed default LSH file FORMAT on serialization.
Wed, 30 Jul 2008 15:22:22 +0000 mas01mc Refactored LSH interface to separate hashfunctions and parameters from insertion/retrieval/serialization
Tue, 29 Jul 2008 22:01:17 +0000 mas01mc Completed merge of lshlib back to current version of the trunk.
