[AMD Official Use Only - General] @Yigit, Ferruh thanks for bringing this to my attention,
The output of the modified ``` Socket 0 Numa 0 ------------------- Core 0 [0, 128] Core 1 [1, 129] Core 2 [2, 130] Core 3 [3, 131] ..... Core 29 [29, 157] Core 30 [30, 158] Core 31 [31, 159] Socket 0 Numa 1 ------------------- Core 0 [32, 160] Core 1 [33, 161] Core 2 [34, 162] Core 3 [35, 163] ..... Core 30 [62, 190] Core 31 [63, 191] Socket 1 Numa 2 ------------------- Core 0 [64, 192] Core 1 [65, 193] Core 2 [66, 194] Core 3 [67, 195] ..... Core 31 [95, 223] Socket 1 Numa 3 ------------------- Core 0 [96, 224] Core 1 [97, 225] Core 2 [98, 226] ..... Core 29 [125, 253] Core 30 [126, 254] Core 31 [127, 255] ``` The intention of the changes is clearly highlighted the NUMA divisioning and CPU pinning within single or multiple sockets. But as pointed out @Dmitry Kozlyuk if the end user will use hwloc on both linux & windows to identify these, we should promote and document the changes provided the existing tool is phased out. Note: there were questions asked in forums, stackoverflow and github on NUMA to CPU pinning, hence enhanced the tool to accommodate the changes. > -----Original Message----- > From: Thomas Monjalon <tho...@monjalon.net> > Sent: Wednesday, June 14, 2023 8:00 PM > To: Yigit, Ferruh <ferruh.yi...@amd.com> > Cc: Varghese, Vipin <vipin.vargh...@amd.com>; Dmitry Kozlyuk > <dmitry.kozl...@gmail.com>; david.march...@redhat.com; Tummala, > Sivaprasad <sivaprasad.tumm...@amd.com>; dev@dpdk.org; Narcisa Ana > Maria Vasile <navas...@linux.microsoft.com>; Dmitry Malloy > <dmit...@microsoft.com>; Pallavi Kadam <pallavi.ka...@intel.com> > Subject: Re: [PATCH] usertools: enhance logic to display NUMA > > Caution: This message originated from an External Source.
