Hi Danilo --
I don't personally have enough experience with GASNet over ibv to
immediately recognize this error, but am Cc:ing the public chapel-bugs
list and chapel-developers list in case someone else does (Rafael?).
[Note that your responses to chapel-developers will bounce unless you're
subscribed, but you should be able to post to chapel-bugs]
it seems likely that the problem is with your GASNet installation rather
than something Chapel specific, so in cases like this, it's often helpful
to run GASNet's test suite that it ships with. To do so, cd to the
subdirectory of $CHPL_HOME/third-party/gasnet/build/ that corresponds to
your configuration (e.g., mine would be linux64-gnu/seg-fast/nodbg) and
then do 'make run-tests-par' or 'make run-tests' (see
third-party/gasnet/GASNet-*/README for more information).
If that doesn't point out the problem, you may also want to turn on
GASNet's internal debugging assertion checks by setting the environment
variable CHPL_COMM_DEBUG and remaking. This will create a sibling to
'nodbg' in the path above called 'debug' and will often be more verbose
about what's going wrong.
Hope this is helpful,
-Brad

Subject: problem with chapel locales
Good morning Mr. Chamberlain,
I'm a PhD student at University of Basel in the High Performance and Web
Computing Group led by prof. H. Burkhart. We introduced Chapel in our High
Performance Computing course and now wanted to exploit our cluster and try the
locales. We have an infiniband interconnection so that our first choice wad to
set CHPL_COMM_SUBSTRATE to ibv. We followed the simple steps shown in the
$CHPL_HOME/doc/README.multilocale file, recompiled chapel and then exported the
environment variables as shown at point 5 of the README, in particular giving
export GASNET_SSH_SERVERS="minta mintb" as locales to be used.
We were able to compile the hello6-taskpar-dist.chpl example, but when running
it with the syntax
./hello6-taskpar-dist -nl 2
we get this error:
GASNet gasnetc_init returning an error code: GASNET_ERR_RESOURCE (Problem with

Are there particular additional configuration steps we have to make before
being able to run chapel locales properly? Or are we making somehow mistakes?
I hope you can help us.
