FWIW dmidecode does the same.

I wouldn't say hwloc is tainted, more that you were tainting the GPL'd code by linking the proprietary code to it, but that's just case of perspective. ;-) After a brief search of the GPL FAQs I'd say the closest I can get is: http://www.gnu.org/licenses/old-licenses/gpl-2.0-faq.html#GPLWrapper # I'd like to incorporate GPL-covered software in my proprietary # system. Can I do this by putting a “wrapper” module, under a # GPL-compatible lax permissive license (such as the X11 license) # in between the GPL-covered part and the proprietary part? # #No. The X11 license is compatible with the GPL, so you can add a # module to the GPL-covered program and put it under the X11 license. # But if you were to incorporate them both in a larger program, that # whole would include the GPL-covered part, so it would have to be # licensed as a whole under the GNU GPL. # # The fact that proprietary module A communicates with GPL-covered # module C only through X11-licensed module B is legally irrelevant; # what matters is the fact that module C is included in the whole. So yes, if you want to permit proprietary code to link to hwloc then you need to stick to permissive licenses in hwlocs dependencies.

That's not been my experience recently; for instance Torque currently creates a cpuset for your job containing all the procs you've been given there and then you can use mpirun/mpiexec to launch orted across all the nodes you've been given. Those processes are then constrained to the allocation set up on each node. They are free to bind themselves to the cores present within that cpuset should they so wish. In the very beginnings (when I was at VPAC and when wew were using MVPAICH2 rather than OpenMPI) Torque would bind processes to a core within the allocation which worked fine for that, but of course broke in the way you explain when we moved to Open-MPI. I fixed that bug up very quickly.. ;-) We've only ever run Slurm on BlueGene where this isn't an issue, so I don't know if that does things differently. > Similarly, if you are running MapReduce, your application has to > figure out what nodes to run on, how much memory will be required, > etc. All that goes into the allocation request (made by the > equivalent of mpirun in that scenario) sent to the RM.

But for the scheduler to be able to plan workload well I believe that once your job has started the best you can do is ask for less than you have been given, otherwise you're free to game the system by queuing a short small job and once it's started asking for many more cores or RAM.. :-) > So we need the capability in ORTE to support the non-direct-launch > cases.

Wouldn't it be the other way around with the resource manager setting limits and then having the job run inside it? Basically like the current cpuset support in Torque, et. al, but on steroids. That way mpirun and/or orted could learn from the kernel the details of the cgroup it is in and arrange itself appropriately.

I would argue that the resource managers *should* be doing it - however, I will also argue that the resource managers should be doing it via hwloc (so I'm afraid it's not an out for you folks :-) ). It's also worth remembering that the memcg code has an appalling reputation with the kernel developers in terms of performance overhead, for instance at the recent Kernel Summit numbers were reported showing a substantial impact for just having the code present, but not used. Following that a patch set was sent out trying to avoid that impact if it's not in use which doesn't help here but does give a measure of the performance hit: http://lwn.net/Articles/517562/ # So as one can see, the difference between base and nomemcg in terms # of both system time and elapsed time is quite drastic, and consistent # with the figures shown by Mel Gorman in the Kernel summit.

I asked via Twitter and got these responses..
# Inline was part of C++98 - the first c++ standard, and

...and...

I note that autoconf has an inline test for C:
http://www.gnu.org/software/autoconf/manual/autoconf-2.67/html_node/C-Compiler.html
But not for C++:
http://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.69/html_node/C_002b_002b-Compiler.html
So perhaps the fact that they've never needed to implement
such a test is in itself a good guide ?

My guess (looking at the BG/P CNK kernel code) is that /sys is not present on a BG/Q compute node, only on its I/O nodes (which run a Linux kernel), and so the code is only picking them up when the I/O is being redirected via an I/O node (i.e. when MPI is in play).

Sounds like your I/O with MPI is getting redirected to the I/O node
(and hence finding /sys from the Linux kernel there) but when you're
running without MPI it's trying to open files on the compute node and
the CNK isn't presenting the /sys directories, causing it to fall back.
I've run lstopo on our BG/P and I get to see the 4 cores there whether
it's the stock code or if I add an MPI_Init() to the start. The
output from lstopo when built with --enable-debug confirms it's
reporting kernel and hostname info from the I/O node associated with
the block:
Machine#0(Backend=Linux OSName=CNK OSRelease=2.6.16.60-304 OSVersion=1
HostName=r00-m1-n04.pcf.vlsci.unimelb.edu.au Architecture=BGP) [...]
It might be interesting to build something like ls with the BG/Q
compilers to see if you can run it on a compute node to see what /proc
or /sys look like in each case.
cheers,
Chris

Not sure about BG/Q, but BG/P uses code derived from MPICH2 according
to: http://wiki.bg.anl-external.org/index.php/Main_Page
Our BG/P seems to claim it's from MPICH2 1.1:

Interesting, so it's not correctly detecting the topology as BG/Q is
16 compute cores, each with 4 hardware threads. Instead it's
detecting all 64 hardware threads and treating them as cores if I'm
reading that
right.
I was puzzled by the OS info output too, it says:
Machine#0(Backend=Linux OSName=CNK
OSRelease=2.6.32-220.el6.bgq110_20120104.ppc64 OSVersion=1
HostName=R00-ID-J04.i2b.cetus Architecture=) cpuset 0xf...f complete
0x,0x online 0xf...f allowed 0xf...f nodeset 0x0
completeN 0x0 allowedN 0xf...f
However, looking at the (open) source code for the CNK [1] (at least
for BG/P) the uname info seems to be derived from the I/O nodes when
its running in CIOD mode, so I suspect that's what's happening here
(looks like a RHEL6 derived kernel from that).

For those unfamiliar with BlueGene (at least P, and I suspect the same
is true for Q), this is because the CNK doesn't implement fork() or
execve(), they're designed to start your code and just keep running it
until it dies.

Apparently so.. rpm --root /bgsys/drivers/ppcfloor/linux/OS -qa | grep -i xml libxml2-2.6.23-22 That's the I/O node filesystem, which is what the compute node kernel maps I/O's back to I believe.

Umm, not sure that'll work on a BG because you can't fork() or execve() on a BG, the IBM mpirun runs on the login node and talks to an mpirund on the service node which then launches the users code on the compute nodes via the Navigator API. cheers, Chris - -- Christopher Samuel - Senior Systems Administrator VLSCI - Victorian Life Sciences Computation Initiative Email: sam...@unimelb.edu.au Phone: +61 (0)3 903 55545 http://www.vlsci.unimelb.edu.au/ -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk5kgRIACgkQO2KABBYQAh+EHgCfQhsNl5axcV+tHQ6jrAJW6Pq6 6EQAn3Dc4qkwoRd23KimXh9rrO0CKz9n =xlWv -END PGP SIGNATURE-

Good guess Brice! This patch to configure from that nightly

Sigh, I think I ended up building in two different

I'll fix that up and send it on again..

Indeed.

Complete guesswork from nm -l /usr/lib64/libpci.a, this
is the object module where __res_query() is referenced:
names-net.o:
r .LC0
000b r .LC1
0072 r .LC10
r .LC11
0087 r .LC12
0030 r .LC13
0010 r .LC2
001a r .LC3
002e r .LC4
003a r .LC5
0041 r .LC6
004d r .LC7
005e r .LC8
0064 r .LC9
U _GLOBAL_OFFSET_TABLE_
U __h_errno_location
U __memcpy_chk
U __res_init
U __res_query
U __sprintf_chk
U __stack_chk_fail
U __strdup
t dns_skip_name
U pci_get_param
0060 T pci_id_net_lookup
b resolver_inited.6042
Now that defines pci_id_net_lookup, and that appears
to be referenced here:
names.o:
r .LC0
0003 r .LC1
0028 r .LC10
004f r .LC11
0054 r .LC12
005b r .LC13
0062 r .LC14
006c r .LC15
007b r .LC16
0081 r .LC17
0086 r .LC18
008c r .LC19
000e r .LC2
0092 r .LC20
0098 r .LC21
009e r .LC22
00a6 r .LC23
00b1 r .LC24
001a r .LC3
0029 r .LC4
002f r .LC5
0039 r .LC6
r .LC7
0046 r .LC8
004e r .LC9
U _GLOBAL_OFFSET_TABLE_
U __snprintf_chk
U __sprintf_chk
U __stack_chk_fail
0160 t format_name
t format_name_pair
0250 t id_lookup
0380 t id_lookup_subsys
U pci_id_cache_dirty
U pci_id_cache_load
U pci_id_insert
U pci_id_lookup
U pci_id_net_lookup
U pci_load_name_list
0460 T pci_lookup_name
U pci_mfree
U snprintf
That defines pci_lookup_name() and that is called from
hwloc here:
$ grep -R pci_lookup_name .
./src/topology-libpci.c:/* starting from pciutils 2.2, pci_lookup_name() takes
a variable number
./src/topology-libpci.c:resname = pci_lookup_name(pciaccess, name,
sizeof(name),
./src/topology-libpci.c:resname = pci_lookup_name(pciaccess, name,
sizeof(name),
./src/topology-libpci.c:resname = pci_lookup_name(pciaccess, name,
sizeof(name),
So my guess it's the fact that we only have a static
library that's causing the linker to pull in all the
symbols, whether needed or not. :-(
cheers!

For the record this happens with system GCC & GCC 4.4,
Intel compilers and PGI compilers on RHEL 5.6 and CentOS
5.6 (both on our SGI CentOS system and a CentOS box run
by another HPC center). I've even tried with ld from
binutils 2.20.1 which was on our CentOS system with the
same result.
Links OK on SLES9, SLES10 and Ubuntu 11.04.

Any extra dependency that's needed for a piece of software to be installed decreases its attractiveness to potential users and (very important to hwloc) integrators. The benefit to sysadmins such as myself of packages using autotools is that they should work with whatever the system has already and not require another package to be installed. Whenever we come across a piece of software we need to install here that uses CMake there's a collective sigh of "oh no, not again".. Think of using autotools as a way of increasing your karma by taking a little bit more pain in return for decreasing a whole lot more sysadmins pain.. ;-) cheers!

Well that fixed that part, "patch" whinged that it was

they were used or skipped I see that when it fails the
dirent->d_type is always '0', but when it works it's '4'.
The manual page for readdir(3) says:
# Currently, only some file systems (among them: Btrfs,
# ext2, ext3, and ext4) have full support returning the file
# type in d_type. All applications must properly handle
# a return of DT_UNKNOWN.
So I'm guessing that reiserfs and GPFS (both of which are
available on this PPC64 box) are returning DT_UNKNOWN (0).
So the above loop will need to catch that and, if it is
DT_UNKNOWN, do a stat or lstat on the entry to find out
what it is. :-(
cheers,
Chris

Looking at the strace and the source seems to show that both builds enter the look_powerpc_device_tree() function (they both access proc/device-tree/cpus) but then on the PPC system it doesn't look any further, whilst on x86-64 it continues happily to look through the rest of the contents of the extracted tar file.

Running coccicheck on 1.0rc4 flags up this construct, I presume
as an ambiguous construction:
if (!topology->flags & HWLOC_TOPOLOGY_FLAG_WHOLE_SYSTEM) {
That's at line 1518 of src/topology.c in hwloc_discover(). The
check file simply says:
// !x combines boolean negation with bitwise and
It's also flagged some unchecked malloc()'s in various bits:
