Abstract
A method for reading a shared clock that is stored in a shared storage space of a storage system, the method may include (a) reading by a compute node a cached value of the shared clock when a time gap before a next update of the shared clock exceeds a time threshold, wherein the cached value is cached in the compute node and is valid during an allowable caching period, wherein the shared clock is shared by a group of compute nodes, wherein a default update of the shared clock has a cycle that exceeds the time threshold; and (b) reading by the compute node a read value of the shared clock when the time gap before the next update of the shared clock does not exceed the time threshold, wherein the read value of the shared clock is stored in the shared storage space.
