YAXT Version 0.10.0 available

Performance improvements for OpenMP and GPU setups
Added by Thomas Jahns almost 2 years ago

This release, apart from a few minor fixes, delivers

an exchanger that performs packing/unpacking via an OpenACC kernel, activated by environment setting XT_CONFIG_DEFAULT_EXCHANGE_METHOD=irecv_isend_ddt_packed, and
multi-threaded MPI messaging for several exchangers (activated e.g. by setting environment variable XT_CONFIG_DEFAULT_MULTI_THREAD_MODE=XT_MT_OPENMP.

Among the minor fixes are

some improvements to configure caching,
more robust interpositioning of defective MPI installs (but we also provide for or link to the patch to build a fixed MPI!),
account for gcc 8.4 fixing a long-standing 8.x problem,
add support for gcc builds with options -fprofile-arcs -ftest-coverage,
use hidden symbols also with nvidia compiler to speed up dynamic linking,
update work-arounds for gcc 12,
restructure xt_request classes to improve future composability, and
adds an interface for byte displacements to stripe MPI datatype generation.
