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.
