OpenHPC KNL cluster runs very slow

OpenHPC KNL cluster runs very slow


Hi,

I have tried to install openHPC with Warewulf stateless provision and SLURM and it runs really slow :-(

HPL benchmark on a normally installed 7210 is around 1700 GFlops but on a Warewulf installed node it is only 140 GFlops more than 10x slower.

I only got 1G ethernet on the nodes and 10G on the master.

How should I install OpenHPC on a KNL cluster, or should I install something else?

Thanks,

Per
