Re: [hwloc-users] NetLoc subnets Problem

Cyril would know better but he's currently on vacation. I don't think the required scotch release is already officially publicly available online. I am not sure what problem you're trying to solve here. This feature isn't really useful if you only have two nodes. It was rather designed for

Re: [hwloc-users] NetLoc subnets Problem

I tried to configure hwloc with scotch, but I still haven't success with that case. I read Chapter 18 in doxygen and chapters about Netloc and installation, but not found about anything about Scotch configure. So, Scotch installed in /opt/scotch-6/ folder, and I want to install hwloc with netloc

Re: [hwloc-users] NetLoc subnets Problem

Inside the tarball that you downloaded, there's a doc/doxygen-doc/hwloc-a4.pdf with chapter 18 about Netloc with Scotch. Beware that this code is still under development. Brice Le 19/02/2017 20:20, Михаил Халилов a écrit : > Okay, but what configure options for Scotch should I use? I didn't >

Okay, but what configure options for Scotch should I use? I didn't found any information about it in docs and readme 2017-02-19 20:52 GMT+03:00 Brice Goglin : > The only publicly-installed netloc API is currently specific to the scotch > partitioner for process

Re: [hwloc-users] NetLoc subnets Problem

The only publicly-installed netloc API is currently specific to the scotch partitioner for process placement. It takes a network topology and a communication pattern between a set of process and it generates a topology-aware placement for these processes. This API only gets installed if you have

Re: [hwloc-users] NetLoc subnets Problem

Hi again! Can I ask you, how can I use netloc API for my C programs? I configured hwloc only with --prefix=/opt/hwloc option. So, there are no netloc header files in /opt/hwloc/include directory. Also, I didn't understand how to use netloc_draw.html, because I found it only in extracted tarball.

Re: [hwloc-users] NetLoc subnets Problem

Please run "hwloc-gather-topology --io foo" on the head node 'Use the gather-topology script that comes with the hwloc nightly snapshot). The output tarball will likely be large, so feel free to send it to me directly. My guess is that your very old kernel may miss some files that we need in the

Re: [hwloc-users] NetLoc subnets Problem

For some reason, lstopo didn't find any InfiniBand information on the head node. I guess running lstopo won't show any "mlx4_0" or "ib0" object. Is the InfiniBand service really running on that machine? Brice Le 17/02/2017 10:04, Михаил Халилов a écrit : > All files in attach. I run

Re: [hwloc-users] NetLoc subnets Problem

Please copy-paste the exact command line of your "netloc_ib_gather_raw" and all the messages it printed. And also send the output of the hwloc directory it created (it will contain the lstopo XML output of the node where you ran the command). Brice Le 17/02/2017 09:51, Михаил Халилов a écrit :

Re: [hwloc-users] NetLoc subnets Problem

Hello As identicated on the netloc webpages, the netloc development now occurs inside the hwloc git tree. netloc v0.5 is obsolete even if hwloc 2.0 isn't released yet. If you want to use a development snapshot, take hwloc nightly tarballs from https://ci.inria.fr/hwloc/job/master-0-tarball/ or

I downloaded gunzip from openmpi site here: https://www.open-mpi.org/software/netloc/v0.5/ There are three identical machines in my cluster, but now third node is broken, and i tried on two machines. They all connected by InfiniBand switch, and when I try to use ibnetdiscovery or ibroute, it

Re: [hwloc-users] NetLoc subnets Problem

Hi, What version did you use? I pushed some commits on master on ompi repository. With this version it seems to work. You have two machines because you tried netloc on these two? Cyril. Le 15/02/2017 à 22:44, miharulidze a écrit : > Hi! > > I'm trying to use NetLoc tool for detecting my
