I apologize for sending this email to all listed authors of the
LinBox code, since while trying to contact some of you I was
getting a return email.
My name is Aleksandr Ovcharenko, I'm the HPC developer of the
Blue Brain Project run by Ecole Polytechnique Fédérale de
Lausanne (EPFL) in Switzerland. I've come across the LinBox
software and would really love to use it for our research as we
run into a lot of linear algebra lately.
Is it possible you could recommend the use of basic data
structures and class objects for the following application. We
are trying to calculate a determinant of a binary sparse matrix
over GF2 (where binary xor operations take place). I've also
read in the paper that some parts of your code run in parallel.
Is there a parallel algorithm for the binary matrix rank
calculation I could use with LinBox?
Thank you very much, I appreciate your answer.
Dear Aleksandr Ovcharenko,
the best list to discuss linbox use is linbo...@googlegroups.com
so I'm ccing it here.
To install linbox, the simplest way is to use recover
then if you have GMP installed on your system, simply run:
Then, I attach here a program that computes the determinant of a
sparse matrix over GF2.
It works with the latest git version (that you get with the script
above, otherwise the stable version needs a patch: file
linbox/algorithms/gauss/gauss-det-gf2.inl is missing).
The attached file is just a variant version of the shipped
