cpus 18-23 on numa node 3. As a result of this issue, software utilities (that
depend on libnuma) are not able to detect the correct number of hardware
threads, hence are not able to launch the right number of software threads.
Please advise. Edit: machine info: - Ubuntu 15.04. - Linux 3.19.0-15-generic.

Anyone have better technical answer about how Power compares to NUMA
which as far as I can tell is mostly a x86 design (some others) for optimizing
memory usage and speeding up performance? I found one small reference to the
fact that Power uses a shared memory bus different then NUMA ...

memory by using a system bus. This model is known as Symmetric
Multiprocessor (SMP). In this model, the distance to any memory location was the
same for all processors. The major bottleneck in an SMP-based system is ...
