[ofa-general] limit on memory registration

[Rui Machado]

Hi all,

is there any limitation on the size that can be registered
(ibv_reg_mr) for communication?
I seem to be limited to 16GB (on 32GB 64bit x86 machine).
Is this normal? Can someone tell me why and/or if there is a workaround?

Thank you very much for the help.

Cheers,
Rui
