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

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
CUDA_cublas_device_LIBRARY (ADVANCED)
linked by target "sgemm" in directory /root/mgbench
-- Configuring incomplete, errors occurred!
See also "/root/mgbench/build/CMakeFiles/CMakeOutput.log".
See also "/root/mgbench/build/CMakeFiles/CMakeError.log".
make: *** No targets specified and no makefile found. Stop.
Does ARM platform cause this problem? What can I do?
P.S. make log as below
CMakeError.log
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.

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