TH73318A - Time synchronization protocol based on switches for Irregular Memory Architecture (NUMA) systems. - Google Patents

Abstract

DC60 (30/07/44) A system and method for synchronizing a set of nodes that have been connected to a central switch in Multi-node data processing system For example, the Irregular Memory Architecture (NUMA) data processing system is initially exposed, the time base register values are obtained. After that, the joint time base register value is determined based on the time base register received from that node. Time base register value. join Each other that has been scheduled will be Broadcast the signal to each node later, before the time base register reading. Group communication to individual nodes In this manner, normal group communication may be reverted. After synchronization by broadcast return Condition of the data group To each node Time-based registers may be read by issuing special purpose interruptions. From the node adapter to One node processor In response to Power adapter Gets a group of read-time baseline data from that switch. Common time-base register value. The same may be determined by selecting many values. Most of the time-based registers are adjusted by correction factors, such as the time required for the moving data group from the central switch to the node processor plus the time required for the mobile data group. That from the node processor to the central switch, the synchronization process may receive periodic iterations. For example by initiating Synchronized every time the Reduce the registers of the central switch down to the system center and a method for synchronizing a set of nodes that have been connected to the central switch in Multi-node data processing system For example, Irregular Memory Architecture (NUMA) data processing systems are initially disclosed and time base registers are obtained. After that, the common time base register value is determined based on the time base register at which such nodes were given, time base register values. join Each other that has been scheduled will be Broadcast the signal to each node later, before the time base register reading. Group communication to individual nodes In this manner, normal group communication may be restored after that. After synchronization by broadcast return Condition of the data group To each node Time-based registers may be read by issuing special purpose interruptions. From the node adapter to One node processor In response to Power adapter Gets a group of read-time baseline data from that switch. Common time-base register value. Each other may be defined by selecting many values. Most of the time-based registers are adjusted by the adjustment factor, such as the time required for the mobile data group from the central switch to cover the node processor, plus the time required for the mobile data group. That from the node processor to the central switch, the synchronization process may be repeated periodically. For example by initiating Synchronize the last time. Reduce the middle switch register value to zero.
