Using ScaLapack inside of a task

[bencteux]

Hello,
is it possible to use ScaLapack as a second-level parallelism ?
How ? Are there references where this is described ?
I explain :
I am implementing a domain decomposition algorithm for computational chemistry.
We divide the orginial problem in subproblems.
In 2D and 3D, each subproblem need to be distributed on several processors due to excessive memory demand. I want to use ScaLapack to solve each of these subproblem.
Thank you very much for help !

A while ago I gave an example on how to run scalapack on only a subset of
the processors, I think that what you are trying to do, have a look at:

Salutations,

That is exactly what I am trying to do.
Thanks !
