Abstract
In a global shared memory (GSM) environment, a method provides local notification of completion of a global shared memory (GSM) operation processed by a first task executing at a local node of the distributed system. The system includes multiple nodes on which different tasks of a single job execute and perform GSM operations that are received from a second task via a via host fabric interface (HFI) and associated HFR window assigned to the first tasks. The local task initiates execution of a GSM operation on the local node. The task then monitors for and detects a completion of the execution of the GSM operation on the local node. When the task detects completion of the execution of the GSM operation, the task issues an internal notification to inform the locally-executing tasks of the completion of the GSM operation.
