The first section of both -- obviously, not the 2nd section of the -v output. :-) The first section of both displays roughly the same information -- the only addition seems to be the phys number of the socket and the machine memory sizes (which don't agree between -v and non-v -- why?). Indeed, the "-v" output seems to remove a lot of whitespace that was included in the non-v output. I just thought it was weird that the -v output is almost exactly the same information (in the first part), but expressed in more lines with less whitespace (L1 and core moved to their own lines). More specifically, if adding the phys number of the socket and the machine sizes is the only information difference, why not add to the same output format as the non-v output? > Samuel > > > ----- > > [7:45] svbu-mpi:~/svn/hwloc % ./utils/lstopo -l > > Machine (3945MB) > > Socket #0 > > L2 #0 (2048KB) + L1 #0 (16KB) + Core #0 > > P #0 (phys=0) > > P #1 (phys=4) > > L2 #1 (2048KB) + L1 #1 (16KB) + Core #1 > > P #2 (phys=2) > > P #3 (phys=6) > > Socket #1 > > L2 #2 (2048KB) + L1 #2 (16KB) + Core #2 > > P #4 (phys=1) > > P #5 (phys=5) > > L2 #3 (2048KB) + L1 #3 (16KB) + Core #3 > > P #6 (phys=3) > > P #7 (phys=7) > > ----- > > > > ----- > > [7:45] svbu-mpi:~/svn/hwloc % ./utils/lstopo -l -v > > Machine (phys=0 local=4039640KB total=4039640KB) > > Socket #0 (phys=0) > > L2Cache #0 (2048KB) > > L1Cache #0 (16KB) > > Core #0 (phys=0) > > P #0 (phys=0) > > P #1 (phys=4) > > L2Cache #1 (2048KB) > > L1Cache #1 (16KB) > > Core #1 (phys=1) > > P #2 (phys=2) > > P #3 (phys=6) > > Socket #1 (phys=1) > > L2Cache #2 (2048KB) > > L1Cache #2 (16KB) > > Core #2 (phys=0) > > P #4 (phys=1) > > P #5 (phys=5) > > L2Cache #3 (2048KB) > > L1Cache #3 (16KB) > > Core #3 (phys=1) > > P #6 (phys=3) > > P #7 (phys=7) > > depth 0: 1 Machine (type #1) > > depth 1: 2 Sockets (type #3) > > depth 2: 4 Caches (type #4) > > depth 3: 4 Caches (type #4) > > depth 4: 4 Cores (type #5) > > depth 5: 8 Procs (type #6) > _______________________________________________ > hwloc-devel mailing list > hwloc-de...@open-mpi.org > http://www.open-mpi.org/mailman/listinfo.cgi/hwloc-devel > -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
