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?
In the device attributes there is an attribute called max_mr_size which
indicate the maximum block size
that can be registered for a device.
There is one more limitation which is a device specific for the
translation table virtual <-->physical
You can check the low level driver of the HW that you are using in order
to increase the size
of this table.
which HW do you use?
Dotan
Thank you very much for the help.
Cheers,
Rui
