we have a number of c6145 machines that we use in HPC context. in order
to get maximum performance out of the nodes (and the IB network in
particular), we would like to set the maximum pcie payload to 256 or 512
bytes. current maximum value is 128 bytes.
normally, this is an option in the bios, but i don't find it (i don't
think the option is there). does anyone know how we could change it? (we
are using SL6 as OS).
any feedback is welcome.
