More Information
Summary:Methods, parallel computers, and computer program products for broadcasting shared variable directory (SVD) information in a parallel computer are provided. Embodiments include a runtime optimizer detecting, by a runtime optimizer of the parallel computer, a change in SVD information within an SVD associated with a first thread. Embodiments also include a runtime optimizer identifying a plurality of threads requiring notification of the change in the SVD information. Embodiments also include the runtime optimizer in response to detecting the change in the SVD information, broadcasting to each thread of the identified plurality of threads, a broadcast message header and update data indicating the change in the SVD information.
