DescriptionWhile MPI is commonly used as a programming model
between nodes for large-scale distributed memory
systems, new programming models such as PGAS are
emerging for many core and new communication models.
PGAS is expected to be one of the programming models for
exascale computing due to light-weight one-sided
communication and low overhead synchronization
semantics. While it is reported that PGAS can take
advantage of its programming model in some applications,
in reality, PGAS programming systems have several
problems in performance and run-time design as a
general-purpose communication layer. And, only one-side
communication by PGAS is not sufficient to implement
whole parallel applications so that it needs to
cooperate with high-level global operations such as MPI
collective communications. We are developing a PGAS
programming language XcalableMP including coarray
extension. In this talk, I will discuss the present
status of PGAS and its future direction with respect to
current dominant programming model MPI+X, and our
experience of PGAS application development will be also
addressed.
