Re: [Starpu-devel] Error find_cpu_from_numa_node: Assertion `current' failed.

Hello

What does lstopo say on this machine? (inside the same reservation)

Do you have CPU-less NUMA nodes? (maybe because of cgroups)

That's the only idea that came to my mind when looking at the code.

Dear Samuel and Starpu-dev,

I am facing an error at the initilization step of StarPU. The error is: core/perfmodel/perfmodel_bus.c:598: find_cpu_from_numa_node: Assertion `current' failed.

How can I solve it? Is it connected with hwloc?

Many thanks,
