A Multi-Threaded Fingerprint Direct-Access Strategy Using Local-Star-Structure-based Discriminator Features

چکیده
Taking advantage of multi-thread technology provided by multi-core in single processor, this paper describes multi-thread implementation on fingerprint direct-access strategy using local-startopology-based discriminator features. Multi-thread was applied for data partitioning on hashing addlookup process, and for work partitioning on similarity score computation. Efficiency of the implementation was achieved, as confirmed by the experiments results. Using quad-thread of dual-core single processor on last tests on experiment, multi-thread implementation can reduce average search time about 17% compare to its single-thread implementation. This result was achieved with relatively same average accuracy trend and has significant improvement by considering millisecond order importance of searching process on large scale data.

Fast and deterministic hash table lookup using discriminative bloom filters
Hash tables are widely used in network applications, as they can achieve O(1) query, insert, and delete operations at moderate loads. However, at high loads, collisions are prevalent in the table, which increases the access time and induces non-deterministic performance. Slow rates and non-determinism can considerably hurt the performance and scalability of hash tables in the multi-threaded par...
