Request: report number of physical chips

[klauspost]

I am a bit unsure about how to do this. I looked at representing the Intel CPU topology, but it is very complex.

Ultimately I think the only way to really do it is through the runtime, since right now you can be rescheduled to any CPU at any time, and any information I could provide is temporary at best. I remember Dmitry Vyukov looked at a NUMA-aware scheduler for Go, but I haven't heard about it for a while.

bit late but...

how could a CPU know if its in a multi-cpu motherboard anyway?

so doesn't that mean that checking the OS is required (maybe bios), which means parsing the output of /proc/cpuinfo is probably the way to go.

i suppose that could be done in this package? maybe with multiple OS support.

since a goroutine can jump from one core to another, I'm also concerned that the information could be garbled in the (unlikely) event that you have two or more different processor models installed...
