Some multi-gpu servers behave differently according to the pci topology and the bus connection to the CPUs. I suggest adding a test that uses CPU affinity in order to check the speed between each CPU/GPU pair.

I'm not sure that this is actually an issue rather than a lack of awareness on my part, but I've observed the following:

After enabling Intel IOMMU in GRUB, benchmarking throws lots of errors during uva such as:

DMAR: [DMA Write] Request Device [ : : . ] fault addr
DMAR: [fault reason 05] PTE Write access is not set

where [ : : . ] and fault addr contain a variety of addresses.

Hi,
I have a problem, I want to use MGbench at ARM TX2 platform.
But when I execute build.sh, it show:

Does ARM platform cause this problem? What can I do?
P.S. make log as below
CMakeError.log

I'd like to refer to this project in a paper I'm working on - is there a specific reference I should use?
