-Elastic Transactions are a complementary alternative to traditional transactions,​ particularly appealing when implementing search structures. Both forms of transactions can safely be combined within the same application. ​ε-STM implementation is faster than state-of-the-art software ​transactional ​memory in various workloads and with a speedup of 36% on averageIt also presents ​speedup over lock-based solutions of 89% on average.+//Elastic Transactions// are a complementary alternative to traditional transactions,​ particularly appealing when implementing search structures.

-ε-STM is the first software transactional memory supporting elastic transactions. Elastic transactions are a variant of the transactional model.

 The simplicity of using ε-STM comes from the very few information the programmer has to provide. The programmer has to indicate whether his(her) transaction is normal or elastic and no extra-information (i.e., release action, or on-abort-action) is necessary. ​ The simplicity of using ε-STM comes from the very few information the programmer has to provide.
