GIV matrix

Dear All,
   
  I need some assitance for running ASREML job. I tried to fit GIV matrix into ASREML. However, it always said that it failed to form G structure and I should increase memory. Currently, my computer only able to allocate 2048MB. The GIV matrix is a lower triangular matrix from 686 x 686 entry. It has three column: row, colomn, and value.
   
  I also try to run the job under unix, it can allocate 4096MB (s9), but when it allocate that memory, it failed to read my data (it able to read my data when I used less memory).
   
  This is the sample of my as file:
  ------------------------------------------------------------------------------------------------------------------------------------
  ESWYT yield combine data
 tid 1 !A
 yea 25 !I
 occ 208 !I
 loc 386 !A
 ent 50 !I
 gen 686 !I
 BLUE
 wt
  
C:\DATA\YLD\stage_2\GIV_browse.giv !skip 1
C:\DATA\YLD\stage_2\yld_cent.txt !skip 1 !AISING
   
  BLUE !WT wt ~ mu !r gen yea.occ.gen
   
  1 1 1
0 0 0 !s2== 0.443036672875
   
  gen 1
gen 0 GIV
  -------------------------------------------------------------------------------------------------------------------------------------
   
  I also try to subset the data and only run with 30 genotype and 17 location. But it still failed to form G scores (memory allocated 2048MB).
   
  However, if I use giv(gen) instead of fitted G structure model, it will converge. Does giv() give the same result as fitted G structure?
   
  Thank you.
