A colleague mentioned to me that he needs to diagonalize (find eigenvalues and eigenvectors) of a symmetric dense matrix with n=10^6 (i.e. the matrix has 10^12 entries). ScaLapack seems to be the way to go for this.
I'm happy to see there is <https://github.com/JuliaParallel/ScaLAPACK.jl>. Saying its documentation is "Spartan" is an understatement. There is a file "test/test.jl" that seems to not be included from "runtests.jl", and which thus might be intended as example. The package doesn't pass its tests. If you know more about whether this just needs a brush-up or whether major surgery is required I'd appreciate feedback. -erik -- Erik Schnetter <schnet...@gmail.com> http://www.perimeterinstitute.ca/personal/eschnetter/
