[0.2.1] - 2020-09-09

Fixed

Fix compilation on Windows by avoiding the TRUE literal as enum value. (8de922e9)
Fix compilation with Boost < 1.67 by using backwards compatible header. (a51c98a7)

[0.2.0] - 2020-09-04

Added

Following the release of the SYCL 2020 provisional spec, master access tasks have been retired in favor of host tasks. These are scheduled in command groups in the same fashion as compute tasks. In addition to master-only execution, they allow distributing host code amongst nodes. (bbf90637)
Celerity buffers are now fully virtualized, meaning that your Celerity application only allocates as much memory as required on each node. (8a203872)
(Experimental) Collective host tasks allow integration of distributed I/O by providing an infrastructure to call MPI collective APIs like parallel HDF5 from within asynchronous Celerity tasks. (bbf90637)
Properly support 3D kernels. (e5543bd0)

Changed

Celerity now uses (and requires) C++17. (5eec3e02)
Celerity should now perform better with large command graphs. (5d876a5a)
Celerity should now be able to automatically assign a unique compute device to each node on a host, given that a sufficient number of devices is available. (9d3da06e)

Fixed

Don't print an error message regarding buffer lifetime for trivial programs (i.e., programs containing no tasks). (ae133458)

Removed

Removed celerity::queue::with_master_access, which is replaced by the more powerful celerity::handler::host_task. (bbf90637)

[0.1.0] - 2019-09-05
