I see it with less as well as 'configure --help > foo'; 'vi foo' or 'less foo' This happens on Fedora 14 as well as SL6 [RHEL6 clone] - but not RHEL5, ubuntu [10.04,10.10] etc. Not sure where its coming form..

Satish, Could you please add this functionality? Hmm, eventually the results have to go into the src directories. How are you going to prevent problems with that?

alternative computation of overlap in additive Schwarz
by Barry Smith 26 Mar '11

26 Mar '11

Daniel Szyld suggests a refined way of computing overlap for additive Schwarz. Instead of taking all rows/columns connected to the block take those with "strong" coupling. I think this could be easily added to PETSc. The paper is at his website: http://math.temple.edu/szyld I've also added this to the projects file. Barry >

fortranstubs,etags are common data for all builds. In case of multiple builds one after another - it was ok to just rebuild each time. With parallel builds - it doesn't make sense to rebuild fortranstubs, etags parallely. Perhaps we need some kind of locking mechanism? The first configure cleates a lock - before starting a build and removes after completion. If a subsequent configure comes to the state fo building etags [or fortranstubs] - it checks the lock - and if it exists - skips the build?

Can temporary files be put in a private directory so that multiple reconfigures can be run simultaneously? I think the rest of configure works. ******************************************************************************* UNABLE to EXECUTE BINARIES for ./configure ------------------------------------------------------------------------------- [Errno 2] No such file or directory: '/home/jed/petsc/src/sys/viewer/interface/f90module.f90' ******************************************************************************* File "/home/jed/petsc/config/configure.py", line 272, in petsc_configure framework.configure(out = sys.stdout) File "/home/jed/petsc/config/BuildSystem/config/framework.py", line 922, in configure child.configure() File "/home/jed/petsc/config/PETSc/packages/sowing.py", line 123, in configure self.buildFortranStubs() File "/home/jed/petsc/config/PETSc/packages/sowing.py", line 83, in buildFortranStubs generatefortranstubs.main(self.petscdir.dir, self.bfort, self.petscdir.dir) File "/home/jed/petsc/bin/maint/generatefortranstubs.py", line 196, in main os.path.walk(dir, processDir, [petscdir, bfort]) File "/usr/lib/python2.7/posixpath.py", line 237, in walk walk(name, func, arg) File "/usr/lib/python2.7/posixpath.py", line 237, in walk walk(name, func, arg) File "/usr/lib/python2.7/posixpath.py", line 237, in walk walk(name, func, arg) File "/usr/lib/python2.7/posixpath.py", line 237, in walk walk(name, func, arg) File "/usr/lib/python2.7/posixpath.py", line 229, in walk func(arg, top, names) File "/home/jed/petsc/bin/maint/generatefortranstubs.py", line 161, in processDir FixDir(petscdir,outdir) File "/home/jed/petsc/bin/maint/generatefortranstubs.py", line 123, in FixDir
