Large Arrays/Commons

[plischke@isam.de]

Hello,

eventually somebody can help (or tell me that there is no solution):

- I have a rather complex finite element code (to be compiled with g77)
  and would like to run
  a bigger model than previously. I have however problems in using
  sufficiently large arrays.
  I split the large arrays into three COMMON BLOCKS, e.g.
  COMMON /A(50000000)
  COMMON /SOL1/ B(28000000)
  COMMON /SOL2/ C(56000000)
  with  IMPLICIT REAL*8 (A-H,O-Z)
 I can compile and link without problems,
 but get a segment violation at excution (immediately, and also if
 a use just a main program for storage allocation (i.e. don't call
 any subroutines)
 I suppose that the maximum storage to be allocated is limited by the
 physical memory of my PC (1 GB), because there are no problems as long
 as the sum of all allocated storage is araound 900 MB. 
 Is there any solution?
 Do you need more information?
 I can also call you on the phone, if you are ready to help.
 Thanks
