### [Lapack] Extended precision arithmetic with LAPACK

 Hello, Apologies if this question has been asked before, but I could not find a relevant discussion in the forum. I am a Physics PhD student and, as part of hydrodynamic stability calculations, I need to solve generalized eigenvalue problems A x = \lambda B x, where the matrix A is highly non-normal. It has been documented in the literature (e.g. Dongarra et al, Appl. Numer. Math. 22, 399 (1996)) that 128 bit arithmetic is often required to obtain numerically accurate results for this type of problems. I was therefore hoping to compile LAPACK to work with 128 bit arithmetic (or any other format that is more precise than double), and would be most appreciative if you could point me to any guidelines/information available on how to do this.. My options are to either work on my home computer (an Apple G4 running OS X), or to use an account on a Linux machine with Intel Xeon processors (I understand the latter option would be far more efficient for extended precision arithmetic). Thank you in advance for your assistance. Best regards, Dimitri
