Solving eigensystem on a cluster

[berthou]

Hello,

I need to solve a symmetric real eigenproblem. I found out that I should usep?sytrdorp?hetrdto reduce the matrix to a tridiagonal form and then usesteqr2from scalapack to get all the eigen vectors and values.

According to the documentation, sytrd andsteqr are threaded functions.

but what about launching an eigensystem solver on a cluster of Xeons processors to use all the computing capability available ?

Thank you.

Vincent.
