Hello,
Thank you to all contributors to hwloc - very useful.
In the FAQ, under the section "What are these Group objects in my
topology?" it says that they are used for "Windows processor groups".
However, I'm either not seeing this, or I'm looking in the wrong place.
On a system with two processor groups, I get:
C:\temp\hwloc-win64-build-1.11.8\bin>hwloc-info.exe
depth 0: 1 Machine (type #1)
depth 1: 2 NUMANode (type #2)
depth 2: 2 Package (type #3)
depth 3: 2 L3Cache (type #4)
depth 4: 12 L2Cache (type #4)
depth 5: 12 L1dCache (type #4)
depth 6: 12 L1iCache (type #4)
depth 7: 12 Core (type #5)
depth 8: 24 PU (type #6)

I definitely have 2 processor groups:
C:\Windows\system32>bcdedit /enum | find "group"
groupsize 6
maxgroup Yes
And you can see this because the processor numbers above in the second
numa node start at 64. Also, calling GetActiveProcessorGroupCount()
returns 2.
I was expecting to get "2" back from:
hwloc_get_nbobjs_by_type(hwlocTopology_, HWLOC_OBJ_GROUP)
but that returns 0. Am I doing something wrong?
Thank you!
David
