[openfabrics-ewg] Welcoming IBM to EWG (Was: : ehca is not in OFED 1.1-rc1 anymore)

Hello Tziporet!
First thanks for your support including our ehca driver in OFED!
At the moment we do have our code in Roland's git tree
git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband.git,
branch ehca. It is based on latest kernel version, ie. 2.6.18-rc4. As
Roland has stated in the mailing list of openib and linux kernel (lkml,
powerpc dev) we're targetting to merge ehca into 2.6.19. In the meanwhile
we have incorporated some received comments in our code and will release a
patch against Roland's git tree by tomorrow, Vladimir, I'd appreciate if
you could pull the code then from there for OFED 1.1-rc3.
According to OpenIB Wiki resp. OpenIBFAQ we have to support 2.6.12 as
latest stable kernel version. So we'll test this and provide a backport if
necessary. That Wiki page also mentions 2.6.9. I'm wondering if backport
for that version is mandatory or not. Can you please clarify that?
We'll provide you with a list of supported platforms (HW and OS) in the
next couple of days.
Thanks,
Hoang-Nam Nguyen

1.1-rc1 anymore)
Hi Marcus and Nam,
I am glad to work with you to include IBM driver (ehca) in OFED.
Note that we already created RC2 yesterday and plan to have RC next week
on Aug-30, so if we want to add ehca we need to move fast.
I guess you already understand the way we work ? code should be compiled
against kernel 2.6.18 tree, and we have back-port patches for the
different OSes we support.
Since ehca is not yet in Linux best if you can setup a git tree with ehca
and its backport patches.
To add ehca you will need to work with Vlad (responsible for the build &
install scripts) and with Michael (maintains the kernel git tree).
Please reply if you can setup a git tree, and if not from where we should
take the code & backport patches.
Also we need to know if there are any platforms (HW & OS) that ehca does
not support.
Thanks,
Tziporet

Now sending this to the EWG email list. Mellanox and Cisco welcomes IBM
to EWG and inclusion of eHCA into OFED. I would like to open this up to
other members of EWG ? Voltaire, SilverStorm, QLogic, for their comments.
Tziporet: Marcus Eder will be IBM's representative to the EWG within
OpenFabrics with Nam Nguyen serving as his back-up. I understand they
will also serve as maintainers of the eHCA driver in OFED.

Sujal,
As we discussed yesterday, when the Board of Directors of the OF Alliance
approved the IWG they did not say they wanted to approve every member of
the group so the IWG is free to constitute itself as it wishes to meet the
tasks and goals the Board approved.
So please bring IBM into IWG ASAP if that is what the IWG members decide
to do.
Bill.

Spoke to Bill further on this yesterday. He will respond. The process

Thank you Sujal!
As we await IBM's inclusion in the EWG would it be possible for you to
include the ehca driver code in OFED 1.1? The code can be extracted from
Roland's git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband.git ehca
Thx!

Hi Chet,
I am copying Bill Boas and Jim Ryan (co-chair and chair respectively of
OpenFabrics) so that they are informed about this request.
Hi Bill/Jim,
IBM needs to be added as a EWG member so that they can start active work
on OFED releases.
If I recall correctly, the process requires the BOD members to vote and
approve IBMs inclusion into EWG subsequent to IBM?s nomination into EWG.
Shawn has already approved IBM?s inclusion and we support that. Could we
initiate an electronic voting to accomplish this quickly?
Thanks,
Sujal

Sujal, Shawn,
I am following up to submit the names of Marcus Eder as IBM's
representative to the EWG within OpenFabrics with Nam Nguyen serving as
his back-up. Marcus's team developed and released the open source ehca
drivers and are best positioned to participate in OFA's EWG to support it
for all future releases.
Shawn, I appreciate your agreeing to support IBM's nomination.
Please copy Marcus & Nam on any necessary follow-ups. Thx!

RE: ehca is not in OFED 1.1-rc1 anymore
Chet,
That is great news. First, IBM should become a member of the Enterprise
Workgroup (EWG) within OpenFabrics and work toward qualifying and
enhancing the driver to meet the release criteria jointly defined by EWG.
There is a voting procedure where board members need to approve. Shawn,
as the chair of EWG, can initiate that process with EWG/OpenFabrics.
After that, you should subscribe to the EWG mailing list and work with the
OFED release coordinator, Tziporet Koren, to get your driver included into
OFED. Given the fact that OFED 1.1 release is imminent (in mid Sept),
there may not be enough time for adequate QA, so there is a possibility
that eHCA support releases as technology preview only in OFED 1.1 and goes
to production status in a future release of OFED. I believe eHCA support
in OFED 1.0 was tech preview only ? I do not recall any of the EWG members
testing the eHCA actively prior to OFED 1.0 release back in June.
Thanks
Sujal

My apologies if you have responded already. If not, could you let us know

Hello Shawn and Sujal!
Could you please tell me the prerequisites if any we need to fulfilled in
order to get your approval for including our ehca driver in OFED 1.1?
FYI: Our driver has been contained in OFED 1.0, but not in OFED 1.1-rc1
anymore.
Due to the short timeframe ahead OFED 1.1 I'd appreciate your helps!

Hi,
To be part of OFED you need to join the EWG and they need to approve
adding IBM support for the package.
I cc Shawn from Cisco (Chairman of EWG) and Sujal from Mellanox and they
can help in driving this.
After it's approved we can discuss the technical details how to add ehca
support to OFED 1.1

Hello Tziporet!
I realized that ehca is not listed and contained in OFED 1.1-rc1. Did we
miss something or can you please tell me what can we do to get ehca in
OFED1.1?

Main changes from OFED-1.0:
===========================
o Bug fixes
o Enabled building 32-bit libraries on x86_64 and ppc64. Note: sysfsutils
and sysfsutils-devel 32-bit required.
o Kernel code based on 2.6.18
o Kernel hot-plug support in uverbs - removing module wait till all user
applications release their HCA resources.
o Package sources (user space and kernel modules) are places under:
<prefix>/src/
Original kernel sources are not replaced
o RDS was removed from the OFED package
o Set options in CMA & uCMA
o OSM new features:
- Partition Manager (Pkey)
- Pre-computed routing load from file
- Primitive QoS - As technology preview
o SDP:
- Improved latency (13 usec with netperf tcprr)
- Implemented Naggle algorithm
- Memory leaks fixes
- Error handling added
o MPI:
- OSU - MVAPICH: Message coalescing to improve message rate
- Open MPI 1.1-1: see changes:
http://svn.open-mpi.org/svn/ompi/trunk/NEWS
- MPI tests: Replace to the new test versions from LLNL,
Intel, OSU
o SRP:
- Stability
o iSER:
- Stability
- Testing more platforms (e.g. ppc64 and ia64)
- Performance improvements
o Management:
- Add saquery tool
- Enhancement to ibnetdiscover tool with grouping function
- New ibutils package:
o Port error counter check
o Port performance counters dump
o Link width and Link Speed check by flag
o uDAPL:
- Scalability features needed for Intel MPI
- Code was updated from trunk
Limitations and known issues:
=============================
1. ipath driver compilation fails on all systems
2. iSER support in install script for SLES 10 is missing
3. SDP:
- 32 bit systems might run out of low memory when opening
hundreds of sockets.
- For Mellanox Sinai HCAs one must use latest FW version
(1.1.000).
Missing features that should be completed for RC2:
==================================================
1. SRP:
- Complete testing with DM (Device Mapper) - for high
availability
- New daemon
2. IPoIB: High availability support using a daemon in user level
3. SDP: support sending/receiving out of band data
4. Add Madeye utility
5. Fatal error support in mthca
