WebNov 4, 2024 · In an optimistic approach, a transaction is executed without any problems of restriction until transaction is committed. The optimistic approach allows the transactions to proceed in an unsynchronized way and also allows conflict checking at the end. This approach is also known as validation or certification approach. WebOct 2, 2024 · Custom C++ Memory Pool for Fast Allocation from Heap Today I will present custom memory pool design which can cut significant allocation time since performance is the greatest concern in C++ programs. The idea is pre-allocating a large block and giving fixed-size pieces to consumers later.
WebAug 10, 2016 · Now suppose I'd like to do this with software-transactional memory instead of locking. Looking at N3919 (or the gcc precursor ), the idea is different. There are no calls such as transaction_start (); transaction_end (); Instead there are function specifiers like void bar () transaction_safe; and block specifiers like transaction { /* body */ }
