Hi, This is just an FYI, I'm sure people are already aware of this. The reference code, when compiling under Linux, uses sysfs. However, the API to sysfs has...
This proposal extends the RDMA semantics to include delivery under a message-based reliable multicast protocol, such as NACK-Oriented Reliable Multicast...
DAT is probably not the correct forum to discuss this, since I believe the implications of multicast RDMA would be neutral to the API. A reliable multicast...
The openib_scm provider was a temporary stop gap while we were waiting for the OpenFabrics rdma_cm interfaces to be developed. This provider is no longer...
Caitlin, I had not looked at this partial multicast case. For Send case, what is the semantic when a buffer is not posted by one of the receivers? A group...
... My hunch is that the receiver without a buffer would have to NACK the packet (if it anticipated that it would soon have a buffer) and drop-out of the group...
Ok, having sparked the discussion, I'd better have some answers for some of the more problematic questions - if not immediately, then in the near future. On...
A new uDAPL branch based on the new DAT 2.0 specification that is ready for testing on openfabrics.org. This version requires OFED 1.2 verbs and rdmacm...
Here is a patch against the published DAT 2.0 headers to align with the OFA build. There are a few changes required for extension support query so please...
Arlin, Many many thanks for integrating DAT-2.0 in. Great job. Some of the changes looks like just extra tabs and spaces. So there have no impact on the spec. ...
You can ignore the tabs/space changes. Just make sure the other 3 changes are ok. dat.h, udat_config.h and udat.h 1. diff -Naur ./dat/include/dat/dat.h ...
Arlin, 1 & 3. Why did you get rid of DAT_EXTENSIONS? I thought we agreed that we will support the non-extension version of DAT-2.0 on default. Changing order...
Hello, I am trying to run dat conformance tests. But I am facing some problems. While running dctest, i am getting segmentation fault. I just want to know...
I have encountered a problem with the DAT 2.0 header files from OFED 1.2 on SLES 10 when using the GNU C++ compiler. The following "program" compiles as a C...

... I not familiar enough with Windows conventions to give you an answer. Perhaps Arlin or someone on dat-discussions has an opinion. james p.s. In the future,...
I am thinking about allowing coexistence of 1.2 and 2.0 libraries for the next release. This will insure that we continue to support 1.2 providers while new...
I think allowing co-existence is very important. Otherwise, commercial software will not be able to gracefully transition from 1.2 to 2.0 over time. --Bill ...

Arlin, how do two proposed way impact configuration files? Thanks, Arkady Kanevsky email: arkady@... Network Appliance Inc....
I am actually thinking about sticking with one dat.conf. For example, OFED would change to look like the following: # # DAT 1.2 and 2.0 configuration file # #...
Then I do not see any problem with multiple libraries. How do you handle the change of signatures between 1.2 and 2.0 in redirection table? Thanks, Arkady...
My understanding is that the RFC just allows the coexistence of different libraries but the consumers are still responsible of handling the difference between...
