Fwd: [workstation-users] MCS compute upgrades next week
by Rajeev Thakur 29 Sep '12

29 Sep '12

Note that crontabs are going to disappear with these upgrades. Anthony and Darius, can you remember to reinstall your crontabs after the upgrade for your machines? See if the crontabs at http://wiki.mcs.anl.gov/mpich2/index.php/Testing_Crons are up to date. I have updated mine.

Fwd: LLNL IO Test?

I ran it in early 2009. It flags problems about unexpected error classes which after talking with RobL it wasn't clear that those were defined in the standard or could be implementation specific. There was also a question of the sync versus sync/barrier/sync. There was also a question of checking MPI_Get_count and if the results were defined for certain test cases in the code. > > I've attached the original source I used, the modified source I ran and the diff of the two.

I'm seeing failures both on my Mac using MPICH2, and on the Cray, using the MPICH2 that they ship. In addition to the error class I reported, I'm seeing problems with MPI_File_get_position_shared and MPI_File_get_size. For example, does it work on BG? I'm going to try it on octopus as soon as I have a recent MPICH2 built. >>>> >>>> Bill >>>> >>>> William Gropp >>>> Director, Parallel Computing Institute >>>> Deputy Director for Research >>>> Institute for Advanced Computing Applications and Technologies >>>> Paul and Cynthia Saylor Professor of Computer Science >>>> University of Illinois Urbana-Champaign >>>> >>>> >>>> >>> >> >> -- >> Rob Latham >> Mathematics and Computer Science Division >> Argonne National Lab, IL USA >

MPICH2 release
by William Gropp 29 Sep '12

29 Sep '12

From the email sent to the wrong account: >> Don't forget that running the nightly tests successfully is necessary >> but not sufficient - there are some important tests that are not run >> by the nightlies, some because they haven't been setup to have >> automatic summaries, others because the nightlies only run on a >> single node. > > We are planning on the special tests too. Are there more? Yes. See the release wiki page http://wiki.mcs.anl.gov/mpich2/index.php/Creating_a_Release . *EVERYTHING* on this page is there because one time we didn't do it, and suffered as a result. All of the 7 items need to be checked. (As noted on the wiki page, we had a more comprehensive and valuable list, with more of those don't-forget-to-do-this-again items; what's here is the absolute minimum for anything that goes to the outside). In addition, some tests need to be run on more than one node (consider that part of #6) - the only such test is a partial test in the special tests, and it has been having some failures for quite some time now.

Commit freeze on trunk
by Pavan Balaji 28 Sep '12

28 Sep '12

Folks, I'd like to call for a commit freeze on trunk for the 1.5rc2 release. The only allowed changes at this point are bug fixes for priority bugs. -- Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji

Email to me is broken
by William Gropp 27 Sep '12

27 Sep '12

For some reason, mail to gropp(a)mcs.anl.gov has been redirected to an account that I check every couple of weeks, instead of wgropp(a)illinois.edu . I didn't request or authorize this change, but it probably represents a significant failure of process rather than a security breach. I've sent email to accounts(a)mcs.anl.gov , but until it gets fixed, if you need me to look at something, make sure you send it to my work email - wgropp(a)illinois.edu .

Special tests broken
by Pavan Balaji 26 Sep '12

26 Sep '12

Many of the special tests are suddenly broken. Many of them seem to be errors with the I/O tests. Some of them are just errors that some directory is not found. Rajeev: something seems to be wrong with the test directory. Maybe delete it and check out again from the svn? -- Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji

1.5rc2 remaining changes
by Pavan Balaji 25 Sep '12

25 Sep '12

I think we are almost ready with 1.5rc2. A few things to do: 1. We need to wait for the nightly tests to run tonight (hopefully they'll be OK). 2. Rajeev, can you start the special tests as well? 3. Dave is working on ticket #1679. I think we can push out 1.5rc2 this week and move fully to mpich-3.0. As a side note, I'm seeing if Cray can help us with the Fortran 2008 bindings. If they can't help us out, we need a backup option. I don't think anyone at Argonne knows how to spell Fortran to do that. Bill: would you be able to help? -- Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji

nightly tests
by Rajeev Thakur 24 Sep '12

24 Sep '12

The builds of the special tests failed last night, which means the nightly tests will also fail. In directory: /sandbox/thakur/cb/mpich2-s/examples CCLD cpi /sandbox/thakur/cb/mpich2-s/lib/.libs/libmpich.a(tcp_init.o): In function `MPID_nem_tcp_get_business_card': tcp_init.c:(.text+0x7fd): warning: Using 'gethostbyname' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
