Nathan, I see a lot of [for once valid] complains from clang regarding the last UGNI related commit. More precisely the MCA_BTL_ATOMIC_SUPPORTS_FLOAT value is too large with respect to the fact that ISO C restricts a enum to int. Can we pack the enums ? George. ../../../../../ompi/opal/mca/btl

fwiw, the onsided/c_fence_lock test from the ibm test suite hangs (mpirun -np 2 ./c_fence_lock) i ran a git bisect and it incriminates commit b90c83840f472de3219b87cd7e1a364eec5c5a29 commit b90c83840f472de3219b87cd7e1a364eec5c5a29 Author: bosilca List-Post: devel@lists.open-mpi.org Date: Tue

Thank you for the response. Nathan, Sure, we will try out your branch and let you know. Any idea when it is likely to be pulled into master ? I presume that our changes, if any, will need to be on top of these changes. Jeff, A few clarifications please: > a) run MTT regularly and submit the re
