[libfabric-users] troubled by FI_SOURCE use

[Biddiscombe, John A.]

Dear list

Everything is working very nicely, but when looking at the feature matrix, I see that FI_SOURCE is not available with the verbs provider. That's a huge PITA because it means a design that work on N platforms won't work on that one and working around FI_SOURCE might mean that every message needs to add that somewhere (I didn't really think it through yet for my parcelport design).

Is verbs FI_SOURCE likely to be implemented one day, or is it something that would require too much intrusive change to the provider code?

Thanks

JB

Thanks. I found the bug. I had not copied an fi_Addr_T in one place before my send operation and so it was always going to 0 - hence the root was receiving it.

Cheers

I realize this is a test app, but you almost never want to use FI_VERSION(MAJOR,MINOR).  Otherwise, if you build with a newer version of the library, it will assume that the app knows of fields and behavior that was introduced in that version.
