Hello folks!
I am doing some matrix diagonalization using Ada-95 for the big frame of
my programs and Fortran-77 for most of the matrix routines. Currently I am
working under HP UX 9.05 (we're upgrading to 10.10 during the next months,
I hope...). Since my matrices become quite large (at the moment 900x900
fortran double precision) I encountered a problem with GNAT. I think there
is a simple solution to the problem, but have no idea were to look for it:
Trying to run the program with still larger matrices my program ends up
with a Segmentation Fault quite at the beginning. My guess is that the
Ada RTS only supplies memory for my data up to an upper limit. Any
suggestions how this can be overcome? (My aim is a matrix of 1800x1800
fortran double precision.) I am not using any tasks, just some generics
and the Interface.Fortran libraries. Sure I also use the usual stuff as
Ada.Text_Io and so on.
Any help is appreciated
Thanks
George Rodemann
