We see many problems with RC4, we've only tested i686 and x86_64 so far
(just started ia64 and ppc64).

1) If the new SDP does not make it in until RC5, I don't see how we can
avoid an RC6.

I agree - and this is what I meant in my mail last week. We plan RC5
with SDP and then RC6 for showstopper bugs.

2) SRP is missing on RHEL4
(http://openib.org/bugzilla/show_bug.cgi?id=51), which is a big
regression.
It was removed on purpose since when running simple tests system is
hanged due to the spin-lock issue in kernel 2.6.9 (see discussion of
Ishai and Doug about this). We can put it back but I don't see a point
in putting something that easily halts the machine or causing kernel
oops. Ishai is working to debug it and once it is solved we will put it
back.
What is your opinion on this?

3) RDS does not load on RHEL4 U3
(http://openib.org/bugzilla/show_bug.cgi?id=61).
SilverStorm should fix this.

4) No MPI for ppc64.
Pasha will try to work with OSU and solve it this week.

5) Open MPI is not working well for Pallas benchmarks, more details to
follow.
That's Jeff's

	    * x86

	    * ia64

	    * ppc64

	*Main changes from RC3:*

	1.      Kernel code based on git (see BUILD_ID for version)

	2.      SRP - with new features: FMR, tunable parameters, SRP
daemon (see details below)

	3.      Open MPI - new package based on 1.1a3

	4.      RDS - new version from main trunk

	5.      Standard network configuration: Network configuration
scripts ifcfg-ib*, located under /etc/sysconfig/network-scripts
(.../network for SuSE)

	6.      /etc/modprobe.conf updated with:
	    alias ib0 ib_ipoib  
	    ...
	    alias net-pf-26 ib_sdp
	Note: this causes unloading the ipoib module to fail on SuSE
(hotplug issue)

	7.      ipath driver available on RH EL4 (up2 and up3).

	8.      uDAPL is available on RH EL4 (up2 and up3).

	*Package limitations:*

	1.      iSER is working on SuSE SLES 10 Beta8 only

	2.      SDP has not been upgraded yet.

	3.      MPI OSU and Open MPI compilation fails on PPC64

	4.      ipath driver compilation fails on FedoraC4.

	*SRP details:*

	SRP new features and changes:

	*       FMR support was added.

	*       Added an interface for removing a target in the
initiator. 

	*       Added an interface for querying the connected targets of
an initiator. 

	*       The SRP tool ibsrpdm can execute as a daemon. The daemon
adds new targets that join the network and removes targets that leave
the network. 

	*       ibsrpdm can use new SM feature: enhanced capability mask
matching (errata MGTWG8372)

	Limitation:

	*       Attempting to add the same target twice fails - to be
fixed in RC5.

	*       The implementation of the target list query must be
modified. The new implementation should create a directory in sysfs for
each target - to be fixed in RC5.

	Please send us any issues you encounter and/or test results.

	Thanks

	Tziporet & Vlad
