Self-tuning in Distributed Transactional Memory [chapter]

Maria Couceiro, Diego Didona, Luís Rodrigues, Paolo Romano
2015 Lecture Notes in Computer Science  
Unfortunately, there is no "one-size-fits-all" design that offers the desirable performance across all possible workloads and scales.  ...  These observations have motivated the emergence of self-tuning schemes for automatically adapting the algorithms and parameters used by the main building blocks of DTM systems.  ...  In the elastic scaling area, for instance, we are not aware of solutions for estimating the impact on performance due to the occurrence of the state transfer activities that are necessary to redistribute  ...
