any body ever fully diagonalize a 200,000 hermitian matrix?

[wdlang]

the matrix is real not complex

anyone ever run it on a station?

i guess parallel algorithm is needed

- What is the size of your matrix ? If the size 200 000, the total size of your pb will 4 X 10^10 X 8 bytes = too big for a station.
- parallel version = scalapack.
-> possible : read the manual
