I announced the end of the Open-MX maintenance to my users in December
because OMPI was dropping MX support. Nobody complained. So I don't plan
to bring back Open-MX to life neither OMPI MX support.
How much would it cost to turn Open-MX into a libfabric Ethernet provider?
I'll pass the hat at SC16...
Presumably you'll need more for the Linux support (for Intel NICs,
obviously).
Assuming MPI-IO, to be on-topic, is MX known to have any real advantage
over TCP filesystem drivers, e.g. Lustre and PVFS?
Both lustre (portals) and PVFS (BMI) have transport abstraction layers.
File systems benefit from native transport (compared to
ip-over-whatever) both in terms of latency (how fast metadata operations
take) and in bandwidth (moving lots of data to/from file system).
not sure if that's what you were asking...
