GASNet-EX: A major specification upgrade and implementation renovation effort is currently in progress:Ĭomputer Languages and System Software Group (CLaSS)įunded primarily by the Exascale Computing Project. The AMįeatures of the core provide a powerful extensibility mechanism which allowsĬlients to implement a wide variety of specialized communication implementing distributed language-level locks,ĭistributed garbage collection, collective memory allocation, etc.). Interface to implement non-trivial language-specific or compiler-specificĬommunication operations which would not be appropriate in a However the client is also permitted to use the core active message Most clients use calls to the extended API functions to implement theīulk of their communication work (thereby ensuring optimal performance across

RDMA support for puts/gets or hardware-offloaded atomic memory operations). Performance of specific operations when hardware support is available (e.g. Of the extended API and implement them directly on the hardware to improve GASNet is structured such that implementers canĬhoose to additionally bypass certain functions in the reference implementation To quickly and easily be ported to a new network architecture by re-implementing We've written a network-independent reference implementation of the extendedĪPI purely in terms of the core API, which allows GASNet (and its portable clients)

Memory access and various collective operations. The GASNet extended API, which provides high-level operations such as remote The upper level is a wider and more expressive interface called Messages, and is implemented directly on top of each individual networkĪrchitecture. Interface called the GASNet core API - the design is based heavily on Active Without sacrificing performance: the lower level is a narrow but very general The design of GASNet is partitioned into two layers to maximize porting ease Opposed to end users), and the primary goals are high performance, interface Intended as a compilation target and for use by runtime library writers (as It has been used to implement parallel programming models and libraries Remote Memory Access (RMA) and Active Messages (AM). Network-independent, high-performance communication primitives including GASNet is a language-independent, networking middleware layer that provides Most of you reading this are part of a community of supportive users and contributors, you have our sincere thanks for making this milestone possible!įor more information, see this coverage in HPCWire. The GASNet team is proudly celebrating 20 years of providing high-quality/high-performance middleware for alternative HPC programming models.
