The output of hwloc-gather-topology is : Machine (phys=0 local=280840KB total=280840KB) Socket #0 (phys=3) Core #0 (phys=0) PU #0 (phys=0) Core #1 (phys=1) PU #1 (phys=1) depth 0: 1 Machine (type #1) depth 1: 1 Socket (type #3) depth 2: 2 Cores (type #5) depth 3: 2 PUs (type #6) Topology not from this system let me know if it's what you want > Samuel > _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
