Alex,
The frag allocation macros take the fragmen
+1 on Rolf's explanation.
Additionally, note that you don't have to do it this way. You can implement

Here is my explanation. The call to MCA_BTL_TCP_FRAG_ALLOC_EAGER or
MCA_BTL_TCP_FRAG_ALLOC_MAX allocate a chunk of memory that has space for both
the fragment as well as any payload. So, when we do the frag+1, we are setting
the pointer in the frag to point where the payload of the message liv
Hi,
As I'm working out the bugs in my component I used TCP as reference and

I don't get it... how/when is this location allocated? Isn't it jus
I second Oak Ridge (or even UTK) sometime in June.

But that changeset have been revert.
Does somebody know if/when it will be added in the trunk ?
Thanks in advance,
