Re: [OMPI devel] Barrier/coll_tuned/pml_ob1 segfault for derived data types

2012-06-15 Thread George Bosilca
There should be no datatype attached to the barrier, so it is normal you get the zero values in the convertor. Something weird is definitively going on. As there is no data to be sent, the opal_convertor_set_position function is supposed to trigger the special path, mark the convertor as comple

Indeed MPI_MAX_PORT_NAME is the right constant. A quick check indicate we're using the right one, so feel free to remove this little piece of historic LAM heritage. george. On Jun 15, 2012, at 00:00 , Jeff Squyres wrote: > On Jun 14, 2012, at 3:53 PM, Ralph Castain wrote: > >> I believe we

(I'm catching up on email from an unanticipated absence - forgive the delay) Pineapple did not hit a roadblock during the call. It is still on track. I will start a separate thread for the discussion. As I have said many (many, many) times, if the pineapple interface needs to change for OMPI/ORTE/

Backing out r26597 solves my particular test cases. I'll back it out of the trunk as well unless someone has objections. I like how you say "same segfault." In certain cases, I just go on to different segfaults. E.g., [2] btl_openib_handle_incoming(openib_btl, ep, frag, byte_len = 20U),

Seems like either a bug in the converter code or in setting up the send request. r26597 ensures correctness in the case the btl's sendi does all three of the following: returns an error, changes the converter, and returns a descriptor. Until we can find the root cause I pushed a change that pro
