I had uploaded kDAPL doc to the file area of dat reflector. Main changes from last version: event formats, memory negotiation proposal, terminology additions...
Regarding the note on SDP I think that writing SDP/SRP protocols over DAPL is probably not so efficient , it looks to me like there is some redundant overhead...

... Actually DAT would provide a very efficient, very readable SDP and SRP. But I doubt that anyone would take an existing SDP/IB package and recode it as...
Good points.., but what's the layer to which SDP and SRP are coded today? Verbs layer? But I don't see API standard today for any IB stack, so whatever they ...
I agree with Caitlin. I worked on the SDP spec for many months in the IBTA. The abstractions that DAT provides are necessary for a ULP like SDP, so you end up...
These are good choices, but need further distinction. High throughput - Blast it Low latency - get some of if there fast as possible. Best effort - Get most of...
Caitlin, I believe you make the point of the temporal nature of the query hint. Yes it would theoretically depend on the TPT usage in the NIC at the instance...
... I had actually thought of "Economy" and "Premium" as: Economy - get it there, eventually, make sure I'm not charged much. Premium - get it there as fast...

Why do we need 3 custom attributes? Thanks & Regards Raja Srinivasan ... From: Topper, Anthony [mailto:topper@...] Sent: Friday, March 01, 2002 3:03 PM ...
Thanks som. My understanding is, SDP is a "below the wire" protocol and would need some sort of an API for application programs to use. The objective of DAT...
Everyone, Yahoo groups for upload is still down, but email is being queued, so I send this via email. I will download the file when yahoo is up again. The...
Raja, Currently the only wire protocol defined in IBTA is SDP (not DAFS, or SRP, ..) So it makes sense to build SDP just on top of the verbs, and not above...

Yaron, You are right, SDP can be coded to verbs layer. But where is the standard API for verbs layer? You can't code to vol 1.0.a of IB spec..... Som. ... or...
Som, how is DAPL going to work with the HCA's It must have a layer with HCA primitives to support multi vendors My assumption is that SDP should be part of the...

Raja, You are right, but my questions were different! Anyway, my point is SDP, SRP, and some amount of "ip-over-ib" are already coded today for InfiniBand...
Som, DAT is not dependent on a standard verbs API. Neither is SDP, SRP or IPoverIB. The issues are the same for any verbs consumer. DAT can already coexist...

Agree with Dave. "Verbs" is a very ambiguous term, that is used by various parties at different levels of abstraction. At the bottom level, the xCA interface...

Dave is correct. DAT on IB is not dependent on any "common verbs level APIs". One can implement it on any lower level: VIEO's CAL, Lane 15 CI, any HCA vendor...
Again, "verbs level" is a highly ambiguous term, since, as Arkady notes, it extends all the way from the transport level down into the silicon. Per my earlier...
