Hi
all,
This is the outcome
of the meeting we had today regarding OFED 1.1 schedule and
features.
Tziporet
1. Schedule:
============
Target release date: 31-Aug
Intermediate
milestones:
1.
Create 1.1 branch of user level code and rc1: 27-Jul
2.
Feature freeze : 3-Aug
3.
Code freeze (rc-x): 25-Aug
4.
Final release: 31-Aug
In general all agreed
but it seems aggressive schedule. We will delay in 1 week if needed or drop
some features.
There was a request
for another OFED release toward SC06 that will include most updated Open MPI
version and we agreed this is possible.
git tree of kernel
code will be available on Sandia servers once their system administrator will
setup the server with git installed (should be this week)
2. Features:
============
Note: features that are under low
priority may not be qualified in final release due to schedule
limitations.
1. OS:
Novell:
- SLES 9.0 SP3*
– SLES10 (official
release)*
Redhat:
– Redhat EL4 up3
- Redhat EL4 up4*
kernel.org:
– Kernel 2.6.17*
* Changes from last
release
Note: Redhat EL4 up2, Fedora C4 and SuSE
Pro 10 were dropped from the list.
We will keep the backport patches for
these OSes and make sure OFED compile and loaded properly but will not do full
QA cycle.
2. General changes:
–
lib32 on 64 bits systems
–
Kernel code based on 2.6.18
–
HCA fatal - full flow support - Low priority
–
High Availability in IPoIB and SRP
–
Bug fixes
3. OSM (new code based on the
trunk):
–
Partition Manager (Pkey) - Low priority
–
Pre-computed routing load from file
–
Primitive QoS - As technology
preview
Mainly developed and verified by
Voltaire.
4. SDP:
–
Beta quality (higher stability)
–
Improved latency
–
Improved bandwidth of small messages (Naggle algorithm) –
done
–
Support the backlog parameter in the listen call
–
support sending/receiving out of
band data
–
Interoperability with previous SDP implementation
We need SDP from Cisco to test the
interoperability with their SDP
5. SRP:
–
GA quality
–
DM (Device Mapper) - for high availability
–
Basic failover/failback testing with
daemon+srp+XVM/MPP and Engenio target
A technical mail was published on the
general list. (Subject: Needed changes to support fail-over drivers). Need
help from Roland to close the technical details since he is SRP
maintainer.
6. IPoIB:
–
High availability support using a daemon in user level
7. uDAPL:
–
Scalability features needed for Intel MPI
–
Going to take the new code from the trunk
8. OSU – MVAPICH:
–
Based on 0.97 (+ bug fixes)
–
Message coalescing
9. Open MPI:
–
Open MPI 1.1.1 - Depending on the dates/schedule of OFED 1.1 and
Open MPI 1.1.1 (If not then Open MPI 1.1 will be used)
–
The major differences between Open MPI 1.1 and 1.1.1 can be seen
here: http://svn.open-mpi.org/svn/ompi/trunk/NEWS
10. MPI tests:
–
Replace to the new test versions from LLNL, Intel, OSU
11. iSER:
–
Stability - code review and bug fixes at iser and libiscsi code
related to error handling (libiscsi is a service module used by both iscsi_tcp
& iser)
–
Testing more platforms (e.g. ppc64 and ia64)
–
Performance improvements
–
The libiscsi fixes are (2.6.18-rc2/3) and will (2.6.19) be
pushed upstream and from there be propagated to distros (eg SLES10 RH5)
through their merge process.
12. RDS:
–
Oracle and SilverStorm should update
Need to decide if RDS should be removed
from OFED since Oracle does not support it for now.
Sujal will check it and we will get to
decision soon.
13: Management:
–
Madeye utility
–
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

Subject: [openfabrics-ewg] OFED 1.1 planning
meeting
Hello all,
We would like to call an OFED v1.1
planning meeting ASAP. We can use
the regular time and call-in number that
Shawn/Jeff from Cisco had set
up earlier. Shawn/Jeff: will you
please confirm and send a reminder?
Some critical feature requirements for
OFED 1.1 are based on customer
feedback on OFED 1.0, specifically some
missing features that continue
the perception of OFED 1.0 as being
inferior to proprietary stacks:
- Support for SLES 9 in
general
- SRP failover and MPP
- SDP usability
- RDS usability
- UDAPL scalability
- High Availability
- Additional OS/CPU platforms support for
iSER, sync with upstream
kernel
- Etc
Thanks,
Sujal
