Instrumentation and optimization of transactional sections execution in multithreaded programs
Труды Института системного программирования РАН, 2018 In this paper, we investigate efficiency of software transactional memory implementation in GCC compiler. The authors propose software tools for instrumentation to profiling programs with software transactional memory, and describe the method of reducing

Open Transactions on Shared Memory [PDF]
, 2015 Transactional memory has arisen as a good way for solving many of the issues of lock-based programming. However, most implementations admit isolated transactions only, which are not adequate when we have to coordinate communicating processes. To this end,

Discovering Approximate and Significant High-Utility Patterns from Transactional Datasets
Journal of Mathematics, 2022 Mining high-utility pattern (HUP) on transactional datasets has been widely discussed, and various algorithms have been introduced to settle this problem. However, the time-space efficiency of the algorithms is still limited, and the mining system cannot

TMbarrier: speculative barriers using hardware transactional memory [PDF]
, 2018 Barrier is a very common synchronization method used in parallel programming. Barriers are used typically to enforce a partial thread execution order, since there may be dependences between code sections before and after the barrier.

Parallel Algorithm for Frequent Itemset Mining on Intel Many-core Systems [PDF]
, 2018 Frequent itemset mining leads to the discovery of associations and correlations among items in large transactional databases. Apriori is a classical frequent itemset mining algorithm, which employs iterative passes over database combining with generation
