Abstract
A distributed computation system comprising computation units and memory shared between computation units, comprises a hardware module for detecting conflicts of access of computation units to shared memory; each hardware module for detecting conflicts configured to: store a probabilistic data structure, indicative of the addresses of shared memory involved in the current transactions; receive at least one message indicative of request for access, by one computation unit to an address of shared memory; determine, from a probabilistic data structure, whether the address is already involved in a current transaction, and transmit a message indicating presence or absence of access conflicts; receive a message indicative or confirmative of reservation or releasing of an address of shared memory, and update the probabilistic data structure for the reserved addresses and the released addresses to be considered, as being/not being involved in a current transaction. A method for using the system is provided.
