Mathieu, Cool, thanks. Satish, Could you please apply the diff to petsc-dev now and then push so any future changes anyone makes will be combatiable with the new code.

Re: petsc-dev recompile needed

Good morning everybody, I finished to modify the code of the library in order to compile the complex version with a C compiler. A few numbers of files have been modified. This modifications include a modification of the file language.py where I put in comment two lines forcing to compile the library with a c++ compiler. Since I don't really know python, I just put them as a comment, but i think it is better to put a message indicating that compiling the complex version of Petsc needs a C90 compliant compiler (gcc 3.4 and after work, it works also with icc) and is experimental. Actually I am working with this modifications and it seems to work like a charm (I had no problem with it). I still need some time to convert the example programs which do not compile but it will be done soon. Note for all of us : Don't use the name I as a variable anymore. It is a reserved word of the language. For most of us, the modifications must be transparent.

Mathieu, I try to avoid I but cannot say for sure. With hg there is an easy way to generate a patch with your changes and then email to petsc-maint(a)mcs.anl.gov then we simply apply it to the master.

Hy, do your modifications include variable name like I (upper i) in your structure. My question seems to be strange but it motivated by the fact that the code will not be compliant if you use a C compiler for complex types (Sorry for that, I am not defining the norms). In fact, I almost made all corrections in the code in order to compile complex version of PETSC with gcc (icc works also), but I didn't send any modifications just because of time. The number of modified files is little and mostly it corresponds to give a different name to the variables. I will do this job again on the last development version of the library and send the modified files to the mailing list if I don't find any others ways. A second point should be noticed. I use the library (complex type compiled with C compiler) and it seems to work correctly. At least I didn't have any difference in the results. However, i think that this option should be used with caution. Mathieu > I have changed some of the data structures for the various AIJ matrix > formats.

I have changed some of the data structures for the various AIJ matrix formats. On you next pull you will need to recompile all the matrix code. cd src/mat make ACTION=libfast tree Let me know if the behavior of the matrices changes due to me update to the code. Barry I'm starting to get the various AIJ matrices to shared more common data structures and code.

Re: Complex matrices with UMFPACK
by Barry Smith 25 Jun '06

25 Jun '06

Christophe, We didn't plan to do it, but if UMFPACK supports complex numbers by compiling in C++ it should be trivial to add. Just edit src/mat/impls/aij/seq/makefile remove the rule at the top that requires real and see what happens when you compile in that directory. You may have to make some minor changes to the file to get it working. Properly completely the job also requires some changes to python/Petsc/packages/umfpack.py Good luck, If UMFPACK supports complex by some non-standard extension of C for the complex data type (like gnu gcc provides) it will not be so simple because we don't currently PETSc working this way. Actually a user was going to add this support but we haven't heard back. It may have been too difficult.

Complex matrices with UMFPACK
by Christophe Geuzaine 25 Jun '06

25 Jun '06

Just a quick question: are there any plans to support complex matrices with UMFPACK in the (relatively near) future? If not, how hard do you think it would be to extend the current integration of UMFPACK to deal with complex numbers? Many thanks for all your work on PETSc: it's proven a very useful and reliable tool over the years!
