python - ompi_evesel->dispatch() failed when running OpenMPI process from Java ProcessBuilder -

-

i trying create java gui control , run mpi process. can run mpi process command line, unable run via java process builder.

i following error after process starts:

[sci053_vm003:02928] ..\..\openmpi-1.6.4\opal\event\event.c: ompi_evesel->dispatch() failed.

i suspect there environment problem, not sure how diagnose it. have printed environment seen java process builder log environment seen mpiexec'd process, see nothing amiss!?!?

all code , output log posted on gist

i trying run in windows environment using openmpi 1.6.4 packaged mpi4py

seems openmpi problem, posted userlist, hoping anywhere can it...

david

ps - able run java program launch , run same code in macos environment, there use brew installed mpich2.

i suspect issue because you're using windows. don't remember when openmpi stopped supporting windows, @ point did. might try using microsoft's port of mpich works on windows , see if need. don't remember url offhand, can find port @ mpich downloads page (http://www.mpich.org/downloads/).

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
