To track that, what does `lscpu` report on your failing system?
(the thread,core,socket lines are probably the relevant ones)
It's an AWS machine of type m6a.large. These are the most relevant
specs.
Thread(s) per core: 2
Core(s) per socket: 1
Socket(s): 1
...
So it seems to have "one core, two threads". I can try changing the n=2
parameter
in the ipp.Cluster invocation to n=1 and tell you if there is any
change,
if it helps. I don't think that will make things worse in any case.
It's worth trying. I've got no reason to think that 2 threads 1 core
should be problem, but I can't think of anything else that would in
principle be different on your system compared to the others that are
not failing.
What it's worth, my own system is
Thread(s) per core: 2
Core(s) per socket: 4
Socket(s): 1
