Hi.
What is the typical size of the MRs that you are trying to register?
thanks

Jack,
The problem I'm seeing is that I'm not able to register even the
default number of memory regions.
The default is 131056 but I'm not able to register more than 32635 regions
I'm on OFED -1.2.5.4 <http://1.2.5.4>.
Any ideas?
Below is the output of lspci and ibv_devinfo -v. I also recently
upgraded to the latest f/w but that didn't make a difference.

To see which device you have, type the following command in your
linux console:
lspci | grep Mellanox
For ConnectX (mlx4), you will see:
InfiniBand: Mellanox Technologies: Unknown device 634a (rev a0)
(lspci has not caught up with us yet).
For Arbel (InfiniHost III), you will see either:
InfiniBand: Mellanox Technologies MT25208 InfiniHost III Ex HCA
(rev a0)
or, if you are running your arbel in Tavor compatibility mode:
InfiniBand: Mellanox Technologies MT25208 InfiniHost III Ex (Tavor
compatibility mode) (rev 20)
===========
If your installed HCA is a ConnectX, you should use the module
parameters for mlx4.
If your installed HCA is an InfiniHost III, you should use the
module parameters for ib_mthca.
