Abstract
Official abstract text for this publication.
Fencing data transfers in a parallel active messaging interface (‘PAMI’) of a parallel computer, the PAMI including data communications endpoints, each endpoint comprising a specification of data communications parameters for a thread of execution on a compute node, including specifications of a client, a context, and a task, the compute nodes coupled for data communications through the PAMI and through data communications resources including a deterministic data communications network, including initiating execution through the PAMI of an ordered sequence of active SEND instructions for SEND data transfers between two endpoints, effecting deterministic SEND data transfers; and executing through the PAMI, with no FENCE accounting for SEND data transfers, an active FENCE instruction, the FENCE instruction completing execution only after completion of all SEND instructions initiated prior to execution of the FENCE instruction for SEND data transfers between the two endpoints.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of fencing data transfers in a parallel active messaging interface (‘PAMI’) of a parallel computer, the method comprising: receiving, at an origin endpoint in the PAMI, a plurality of non-blocking SEND instructions from an application, wherein each of the plurality of SEND instruction specifies a data transfer from the origin endpoint to a target endpoint in the PAMI: receiving, at an origin endpoint, a FENCE instruction corresponding to transfers…
