Re: [OMPI users] TM fixes on trunk
For lack of a longer explanation, let's call it "internal accounting errors" :-). In an attempt to speed up the TM launcher, we made some changes in Open MPI 1.1 which ended up using the TM API the wrong way. So it was clearly a bug. It *might* work in 1.1, but I wouldn't recommend it (i.e., it's a timing issue -- sometimes it might work, sometimes it might not). More specifically -- if it's working for you, then it will probably continue to work for you. There is a 1.1.1b2 tarball currently available (http://www.open-mpi.org/software/ompi/v1.1/), and there are nightly snapshots of the 1.1 branch available as well (http://www.open-mpi.org/nightly/v1.1/). You can see a full list of the changes in the 1.1 branch in the "1.1.1" section of NEWS: http://svn.open-mpi.org/svn/ompi/trunk/NEWS > -Original Message- > From: users-boun...@open-mpi.org > [mailto:users-boun...@open-mpi.org] On Behalf Of Caird, Andrew J > Sent: Monday, July 17, 2006 11:10 AM > To: Open MPI Users > Subject: Re: [OMPI users] TM fixes on trunk > > Jeff, > > What were the details of the problem/fixes? > > Is it worth us moving to the trunk or using what we have until 1.1.1 > arrives? > > Thanks. > --andy > > > > -Original Message- > > From: users-boun...@open-mpi.org > > [mailto:users-boun...@open-mpi.org] On Behalf Of Jeff Squyres > > (jsquyres) > > Sent: Monday, July 17, 2006 10:22 AM > > To: Open MPI Users > > Subject: [OMPI users] TM fixes on trunk > > > > All -- > > > > Martin Schaffoner reported some TM problems to this list a > > little while ago.

Re: [OMPI users] TM fixes on trunk
Jeff, What were the details of the problem/fixes? Is it worth us moving to the trunk or using what we have until 1.1.1 arrives?

[OMPI users] TM fixes on trunk
All -- Martin Schaffoner reported some TM problems to this list a little while ago. It took a long time for he and I to synch up, but we finally identified and fixed the problem. This only affects Open MPI 1.1 installs -- it is not an issue for 1.0.x installs. The fix has been included in both the trunk and the 1.1 branch, and will be included in the upcoming 1.1.1 release. -- Jeff Squyres Server Virtualization Business Unit Cisco Systems
