Vladimir Ozerov resolved IGNITE-2316. ------------------------------------- Resolution: Won't Fix Profiling didn't show any benefit even in local benchmarks. Hence, closing as "Won't fix". Implementation is attached. May be we will back to it later. > Replace GridSpinBusyLock with improved version of GridStripedSpinBusyLock > ------------------------------------------------------------------------- > > Key: IGNITE-2316 > URL: https://issues.apache.org/jira/browse/IGNITE-2316 > Project: Ignite > Issue Type: Sub-task > Components: general > Affects Versions: ignite-1.4 > Reporter: Vladimir Ozerov > Assignee: Vladimir Ozerov > Fix For: 1.6 > > Attachments: GridStripedSpinBusyLock.java > > > 1) GridStripedSpinBusyLock is not striped properly at the moment - produced > AtomicIntegers are located too close to each other to produce considerable > amount of false-shares. To fix it, int state of each lock should be padded > with dummy values. This will give significant throughput increase. > 2) Then GridSpingBusyLock must be replaced with GridStripedSpinBusyLock all > over the project. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
