Fixed in https://svn.open-mpi.org/trac/ompi/changeset/15850. I alsoadded much more descriptive error messages. FWIW: I've refrainedfrom adding text to the FAQ yet about the receive_queues MCAparameter because we will likely be changing some of the parametersdue to changes in credit accounting in the not-distant future.


Thanks for pointing out the problem, Tim.

(Jeff kills all remaining MTTs still running from last night sinceall the openib testing will fail...)

#$@#$  I see what happened.  The help string for the MCA parameter
said "colon" (and that's the string that I sent out last week and
pasted into the code yesterday), but the parser was actually checking
for semicolons.

Looks like the parsing is wrong for the QP specification.

@#!@#$@!#$ I swear I checked this before I committed, but apparently
I must have goofed.  I'll go fix now...

This might be breaking things on odin. All our 64 bit openib mtt

have the following output:

[odin003.cs.indiana.edu:30971] Wrong QP specification (QP 0

Point-to-point QP get 1-5 parameters

However, on my debug build I do not get any errors. Is anyone else
seeing this?


Just checked the mtt webpage for our viscluster which is 64. And It
shows the
same error message. By locking to the commit it looks like that the
first
triple has been extended to a quadruple ?

Cheers,

Thanks,
