A new stable of MPICH, 3.3.1, is now available for download. This is the
first bug-fix release in the 3.3.x series. All production environments
are encouraged to upgrade.
The MPICH 3.3.x series contains a new (non-default) device layer
implementation – CH4. CH4 is designed for low software overheads to
better exploit next-generation hardware. CH4 supports the OFI
(http://libfabric.org) and UCX (http://openucx.org) libraries for
network communication. Building support for both can be done as follows:
./configure --with-device=ch4:ofi,ucx
An environment variable is used for runtime netmod selection.
MPIR_CVAR_CH4_NETMOD=ofi
or
MPIR_CVAR_CH4_NETMOD=ucx
CH4 is experimental, meaning there are known build issues and bugs, but
most tests and common benchmarks will complete on 64-bit Linux systems.
You can find the release on our downloads page (www.mpich.org/downloads)
Regards,
The MPICH team
