Agenda Bashing
Administrivia
OLS paper almost complete
Next meeting 5/11
AR Review
Kernel update
nothing upstream yet
2.6.12 taking time to stabilize
memory pinning still under discussion
converged (except for Caitlin)
implementing to that
SuperComputing 05
2 activities proposed for November
infrastructure for SCInet (IB interconnect)
customers rather than vendor managed
optical technology issue (4x to 4 parallel optic dongle)
switches provide power
(unused ground now need to be driven by
switches)
Some Topspin switches and Mellanox HCAs
support this
(software transparent)
Tutorial
for customers
virtual networks
Xen
currently not supported
not started on
started investigating architecture
substantial risk
target end of next week strawman to
openib and xen lists
November tight
plan to do without virtualization
2.6.9 patch
svn 2245 building
user mode verbs works, IPoIB
one SDP issue
still IA64 issue (firmware ?)
EM64T works
2.6.9 backports whenever OpenIB goes upstream
missing some get_sb_psuedo so need custom kernel
IPoIB needs this
that could be pulled so user veerbs as binary could be made to
work
but not IPoIB
add patches to source and build new kernel RPM ?
patch based on 2.6.12-mm3
split into kernel, base drivers, fixup
need to be put into subversion somewhere
waiting for 2.6.12 to be released
latest code to 2.6.9
user mode support
IA64 issue ?
SDP also
RedFlag request
RedHat also 2.6.9 based (RHEL4)
would they pick this up ?
TriLabs will be using RHEL4
latest non SLES 2.6.11
RedHat Fedora
support issue for this ?
leave to distro
MPI
nothing new to report here
No news from Tim
DK released MVAPICH 0.9.5 lastweek
starting to look at gen2
Tim (LANL) 1-2 months OpenMPI on OpenIB
RC with Steve Poole
Matt started on LA MPI (UD)
Intel MPI over uDAPL is running
Status of Current Tasks
Sean: RMPP
responding to emails and retesting
already changed API to remove userspace parameter
working with InfiniCon on CM (Bill Jordan)
REJ on bad request
Libor: user CM
Arlin not yet started on this
posted last week with simple example
working on more sophisticated example
uses IB verbs
need to get path record
Roland: user verbs
changes to memory pinning being implemented
kernel patch for DONT COPY flag on mprotect/mmap (fork support)
reference counting of overlapping regions
ultimate ALWAYS COPY for partial pages
is this usable for 2.6.9 ?
RedHat can't change kernel ABI
does this do that ? change symbol versions
IA 64 details
general cleanup
remaining: large number of minor pieces
attach/detach mc QPs, some query verbs (GID table)
fair bit of loose ends still to do
documentation
2 more weeks for initial release ?
tar balls and RPMs
Shahar/Hal:
Worked on user_mad.c, libibumad, and OpenSM to support RMPP
on the send side
Next week work on receive side
bad port handling algorithm finally converged
needs be implemented
OpenSM initialization times
RARP
Solaris snoop real fix still pending
cluster diag testing completed by Josh
Bugzilla (overhead)
revisit later (~ 1 month)
Should Mellanox be part of this call ?
at stage 2 when have a piece of PF
OpenSM ? verification ? other ?
Other/Associated Project Issues
Work split between Roland and Libor
additional features (priority order)
user space events (port state, LID/SMLID changes)
user space snoop MAD
IPoIB partial connectivity
osmtest to be supported ?
Plugfest/IL list may be possible in April 05 as DTA is likely to be
dropped as requirement
vote this week at CIWG
SM client reregister/IPoIB reregistration for multicast groups
EUI-64 and IPoIB
HCA capability mask
