sdk100_ibal1-285++.tgz

This release has been running in the lab for over 70 days without failure, so this release can be viewed as the first production quality release. It runs on 2.4 based kernels on IA32 and IPF.
For 2.6 based kernels, go visit openib.org.

Alpha Stack Now Posted in BitKeeper

The Alpha 1 release for the Linux InfiniBand Project
is now posted in the project's BitKeeper repository (http://infiniband.bkbits.net/). Refer to
label "alpha_release_1". The release consists of:

* Kernel mode components: IB Access Layer,
IPoIB, SDP (the Mellanox HCA VPD must be
obtained directly from Mellanox)
* User mode components: uDAPL, OpenSM
* Configuration: IA-32, SMP, debug builds only
* Basic functionality only - performance
characterization and tuning still needs to be undertaken... read more

SDP now available in BitKeeper

SDP has now been placed in the Bitkeeper source
repository.

At this time, SDP has only been validated on
Mellanox Profile B hardware. Besides this
hardware, you will need the latest sources from
http://infiniband.bkbits.net and the latest drivers
and firmware from Mellanox.

Also, the patches necessary for 2.4.18 based
kernels is placed now in BitKeeper for both IPoIB,
and for OPS. For transparent offload to SDP for
legacy TCP applications, a patch to socket.{ch} is
also available in BitKeeper under the directory
base/linux/patches.

More stable IPoIB stack now available

Now posted in the "InfiniBand" files area is the
latest drop of the SourceForge Linux InfiniBand
Project stack.

With this drop, IPoIB (IP over InfiniBand) is now
much more stable. Improvements include:
- IOMeter run successfully for 48 hours
- Completed overnight runs with IPoIB in a 6 node
cluster
- Enabled multicast support across multiple
switch fabrics

At present, the stack only runs via the HCA driver
supplied by Mellanox. Note: At this time the
Mellanox driver is obtained from Mellanox directly
via their DDK and is not posted to this project.
Refer to the Mellanox web site at
http://docs.mellanox.com under

First drop of operational IPoIB

Now posted in the "InfiniBand" files area is the latest drop of the SourceForge.net InfiniBand project stack. With this drop, IPoIB (IP over InfiniBand) is now functional with the Profile B HCA from Mellanox. (At present, the stack only runs via the HCA driver supplied by Mellanox, included in their DDK.)

Note: At this time the Mellanox driver is obtained from Mellanox directly via their DDK (and is not posted to this project).... read more

First drop of operational "Profile B" stack

Summary: With this drop, the opensm is now
functional with the Profile B HCA from Mellanox.
opensm can configure a point-to-point fabric
(without a switch) via the Access Layer and the
HCA driver supplied by Mellanox. Note: At this
time the Mellanox driver is obtained from Mellanox
directly via their DDK (and is not posted to this
project).

Other items of note include:
- Complete SMI/GSI implementation in AL
- Multicast functions implemented on AL (SA
multicast support is being tested)
- First code drop for SRP (Code Complete, but not tested)... read more

Linux InfiniBand Project now online!

The Linux InfiniBand Project (http://sourceforge.net/projects/infiniband) is a collection of sub-projects focused around the common goal of providing the components needed to support an InfiniBand fabric, specifically for the Linux operating system.

This initial site posting includes several architecuture specifications and a source drop of Early Reference Code.

The Early Reference Code includes Linux drivers for storage, networking, and IPC, plus a collection of InfiniBandtransport (infrastructure) drivers that provide access to the HCAs. It provides reference code that runs on the Intel 82808BA HCA hardware. It is provided primarily as an example reference implementation for use by developers ofInfiniBand open source projects, IHVs developing target hardware, or ISVs wanting to gain some experience with or do early development onInfiniBand software. ... read more
