Hello all Per last week's telecon, we planned the merge of the latest ORTE devel branch to the OMPI trunk for after Sun had committed its C++ changes. That happened over the weekend.
Therefore, based on the requests at the telecon, I will be merging the current ORTE devel branch to the trunk on Wed 2/13. I'll make the commit around 4:30pm Eastern time - will send out warning shortly before the commit to let you know it is coming. I'll advise of any delays. This will be a snapshot of that devel branch - it will include the upgraded launch system, remove the GPR, add the new tool communication library, allow arbitrary mpiruns to interconnect, supports the revamped hostfile and dash-host behaviors per the wiki, etc. However, it is incomplete and contains some known flaws. For example, totalview support has not been enabled yet. Comm_spawn, which is currently broken on the OMPI trunk, is fixed - but singleton comm_spawn remains broken. I am in the process of establishing support for direct and standalone launch capabilities, but those won't be in the merge. I have updated all of the launchers, but can only certify the SLURM, TM, and RSH ones to work - the Xgrid launcher is known to not compile, so if you have Xgrid on your Mac, you need to tell the build system to not build that component. This will give you a chance to look over the new arch, though, and I understand that people would like to begin having a chance to test and review the revised code. Hopefully, you will find most of the bugs to be minor. Please advise of any concerns about this merge. The schedule is totally driven by the requests of the MPI team members (delaying the merge has no impact on ORTE development), so requests to shift the schedule should be discussed amongst the community. Thanks Ralph
