Dear Boards members,

I want to calculate the eigenvalues of a large matrix using 16 nodes.

I am using PZHEEV as solver and PZELSET to distribute the matrix to the notes.

This all works fine. PZHEEV returns INFO=0.

My question is now how can I efficiently collect the eigenvalues from the nodes?

I tried PDELGET (eiegnvalues are real here) with little success. I can write them

to a file using PDLAWRITE, but that is not useful if post-processing of the eigenvalues is needed.

One could work with MPI_SEND etc using all the details of the processor grid. I hope that

there is a simpler solution for this standard problem..

I googled a lot over the lats couples of days without success.

Any hint would be most welcome.

Thank you in advance.

Kurt
