Hi guys
I use hwloc-1.0rc1 on AMD Barcelona machine (AMD Opteron Processor
8350). But, it looks like hwloc-1.0rc1 detects my machine with a problem:
lstopo command output information is below:

I'm not sure whether hwloc gave out the correct information. From my
understanding, L3 cache should be shared by for cores in each socket;
and L1 cache size shouldn't be 512KB. Are there somebody to confirm it?
Thanks
