GPU related stuff
Hi all, Some time ago on this list, there was some discussion about GPU and a GPU version of PETSc. I would like to know if there has been any progress. Also, I need some advice on preconditioners suitable for GPU platforms. May I know what platform/language you are using, e.g. nVidia/CUDA, ATI/ATI Stream SDK or OpenCL? Best regards, Farshid Mossaiby
[PETSC #18705] PETSc and Cygwin License (POSIX layer)
Hi all,
I am really glad to hear this. This is exactly what I wished, and told you some
time ago.
Just wanted you to know that there is a Windows Services For Unix (SFU)
add-on for Windows, which is in some way like Cygwin. It is free, and can be
downloaded by everyone. It has support for unix paths, too. I really do not
like it (even as much as Cygwin), but it can be somewhat useful for you /
someone else, if you take a look at it:

Indeed. However, at some time I'll try to make PETSc
build with Scons.
But we need to fix configure first.
Config/configure.py uses the SHELL constantly for
basically everything. Try
running config/configure.py
under Windows without using cygwin.
I tried at home to run it with standard Windows's
Python and
MinGW+MSYS, but I had no success up to now (however, I have
not tried
hard)
I for one think it should be possible to remove
'make' from the
toolchain, leaving us with only win32fe, which we
distribute. Thus
I think we could abandon cygwin once and for all.
I would even be
willing to write a \emph{make clone} to
accomplish this, even though
I am a committed enemy of make (which once
TP'ed my house).

Stefan,
Here is my understanding of the situation.
Conjecture: You CAN use an open source compiler
(GNU) to compile
proprietary code and then sell
the binaries without making the proprietary code
GNU licensed so long as
you just use the
GNU compilers out of the box and don't change
their source code and don't
include the compliers
libraries in your binaries.
IF this is true then you are safe, the Cygwin
environment is only used by
PETSc to have
a system to compile PETSc. None of it is included
in the binaries
generated.
On the other hand, if my initial conjecture is
wrong, then there could be
a problem.
Barry
We've tried over the years to use Windows
posix environments to develop
a build system
for PETSc so we don't need cygwin to build
PETSc. Unfortunately their
stuff is so un-unix
like that it just wasn't practical and using
developers studio to build
PETSc directly is
possible but requires some how getting all the
PETSc source properly into
developers studio
and as far as I know the only way to do this is
manually through the gui
which is very painful;
plus if we change something in the Unix build side
later we'd need to
change it manually
on the developers studio side.
If the situation has changed and Windows does
provide a reasonable way to
build large
unix codes I'd love to hear about it and use
it. We hate cygwin but feel
with have no other
reasonable option.

Dear PETSc developers
Since a while, I successfully use your fantastic
library on Windows. Thank
you very much!
Lately, I had a discussion about the involved
copyrights/licenses with a
colleague. The main point was if PETSc requires
the POSIX layer of cygwin on
Windows (and therefore would need to fulfill
cygwin's GPL license).
My standpoint was that cygwin is just used to
configure and build the
library, but only native Windows libraries (using
MS or Intel's Windows
compiler, MKL) are finally linked to the PETSc
libs. However, I have
difficulties to proof this claim, which is the
reason for this email.
Please comment/clarify the licensing on a Windows
system.
Thanks a lot for your informations.

It's pretty slow for large projects and the caching design seems to generate inconsistent state somewhat regularly. Also, big projects seem to always end up with a fork of SCons or abandon it for alternatives. I've been using CMake for my stuff (linking against PETSc and a few other libs). The syntax is pretty hideous for scripting, but the declarative build definition is very nice. Since it uses the native build system, the IDE-using people on Windows would probably prefer it as well. It would be trivial (like an hour, plus some for tests) to replace the current recursive make with CMake, replacing BuildSystem would obviously require a bit of tedium, if it was even desirable. BuildSystem is a very different beast from the configuration tools that are out there since it also fills in as a package manager (extremely nice since lots of optional dependencies have really painful build systems). In any case, having proper dependency analysis would be *really* cool, a do-nothing rebuild of ParaView (includes VTK, 2M LOC in many directories) takes 10 seconds so the usual PETSc few-file recompile after 'hg pull -u' would be a 2-second affair. Anyway, I'd suggest having a look at CMake before implementing an SCons build. Jed
petsc and x-fem
Hi, I always liked idea of a *simple* parallel FEM code in Petsc, which shows most of tricks used in various programs, like parallel assembly of elements and imposing Dirichlet BCs in a proper way. I think this can eliminate many of How should I do that questions from newbies like me. I think this is almost a series of copy-paste's for you. With a little documentation this would be a great help.

Dear Satish, First, thanks for your reply. Hmm - not sure I understand this - but Cygwin is one version of Python GNU utilities compiled for Windows. What alternative are you thinking of? I meant Python for Windows, what I can download from www.python.org, but as far as I am experiencing, it is not possible at least in case of Python. On the machine I am testing on, Python was installed. Beginning to configure PETSc, I got an error about os.getuid(). Sorry, I missed the exact error message. I installed the Python which comes with Cygwin and it went OK. For other utilities, I was thinking of Interix (SUA in Windows 2008) for example... You can give it a try with the instructions for Using Visual Studio 2005 and let us know if you encounter errors. Well, I have been able to reach second step of building PETSc (make all test currently running). The only error message I have got till now is: Warning: win32fe: Path Not Found: c:\PROGRA~1\MICROS~1.0\SharedIDE\BIN I am not sure what this means...
