Simplifying concurrent algorithms by exploiting hardware transactional memory
We explore the potential of hardware transactional memory (HTM) to improve concurrent algorithms. We illustrate a number of use cases in which HTM enables significantly simpler c...

Lightweight, robust adaptivity for software transactional memory
When a program uses Software Transactional Memory (STM) to synchronize accesses to shared memory, the performance often depends on which STM implementation is used. Implementation...

Delays induce an exponential memory gap for rendezvous in trees
The aim of rendezvous in a graph is meeting of two mobile agents at some node of an unknown anonymous connected graph. The two identical agents start from arbitrary nodes in the g...

Brief announcement: byzantine agreement with homonyms
In this work, we address Byzantine agreement in a message passing system with homonyms, i.e. a system with a number l of authenticated identities that is independent of the total ...
