Tools

  • bind process on 2 cores "near" physical proc id 3 ?
    • hwloc-calc: add an option to request a cpuset containing of n close entries among the generated cpuset
  • internationalize the output of lstopo? object types and memory size units
  • hwloc-top, like lstopo, but keeps printing every 3s or so, and show bound threads as well as the used CPU%

Doc

  • automatically generate the pngs?
    • see doc/images/HACKING

Support

  • add info about supported instructions (sse, avx, ...)
  • add info about available execution units (fpu)
    • and say if they are shared between threads/cores
      • this could help improving the current ambiguity between two real cores, one hyperthreaded core, and AMD dual-fake-core compute units
  • reduce distance matrices so that parent objects get distances between them as well (just like we do when computing group distances after inserting groups)
  • parallelize the discovery ? :)

I/O

  • CCI interoperability to get cci_device and/or cci_device->name locality
    • use cci_device->pci.{domain,bus,dev,func} to retrieve the PCI device
    • wait for the CCI API to be stable
  • Add a ofed plugin to gather ofed device info without relying on Linux sysfs
    • Not sure whether ofed works the same on other OS anyway

Backends and Ports

  • Try to make the distance grouping code a separate component ?
  • QNX
    • _syspage_ptr() SYSPAGE_ENTRY(entry)
    • ThreadCtl/Thread_ctl_r(_NTO_TCTL_RUNMASK)
  • BSD
    • sys/sched.h: sched_bind/sched_unbind, but that's in-kernel only for now.
  • AIX
  • Cray Catamount?

updates:

  • AMD magny-cours support is OK
  • numa distance in XML is in array of stringified infos #32
  • envvar are properly documented (except the ugly debugging one, on purpose)

Date: 2010-05-25 11:28:20 EDT (Tue, 25 May 2010)
New Revision: 2142
URL: https://svn.open-mpi.org/trac/hwloc/changeset/2142

Log:
When nothing (except options) is given on the hwloc-calc command-line,
read from stdin and process line-by-line. Multiple objects in the same
line should be separated by spaces.
