Hi all,
There seems to be a whole lot of misinformation out there about the appropriate
setting for the log_mtts_per_seg parameter in the mlx4 driver. Some folks
suggest that it’s different between the RHEL/kernel.org provided driver and
Mellanox OFED, some suggest it’s been fixed such that the default can assign 2x
the total memory on a node since at least RHEL6.6 (and so one would assume even
longer ago in OFED), and some places seem to still be carrying it forward
because “maybe it matters.”
Is anyone here sure of the current state? I’ll probably read the source code if
not, but I’d like to spare myself the hassle.
