Comment (by kuszinger):

 '''NC''': used '''elevation''', the whole, set g.region res=5 so the
 target dataset is bigger, it ran well with good results. Anyway, the
 source dataset is not sparse. I''' rerun on the NC elevation and making it
 sparse with random nulls, ok?'''

 '''6.4: yes, worked like charm''', less than 2GB memory usage (same
 machine same everything).
 One more extra: while the above debug region is:



 {{{
 projection: 1 (UTM)
 zone:       48
 datum:      wgs84
 ellipsoid:  wgs84
 north:      1529314.78008
 south:      1528778.59005
 west:       448590.883652
 east:       449308.347889
 nsres:      0.19999628
 ewres:      0.20001791
 rows:       2681
 cols:       3587
 cells:      9616747

 }}}

 the whole map which was successfully interpolated in 6.4 was:



 {{{
 projection: 1 (UTM)
 zone:       48
 datum:      wgs84
 ellipsoid:  wgs84
 north:      1525100
 south:      1522400
 west:       449885
 east:       453027
 nsres:      0.2
 ewres:      0.2
 rows:       13500
 cols:       15710
 cells:      212085000
 }}}

 so, my packed sample is only a cut of which was successfully processed in
 6.4

 Anyway, I try NC with its modified eleveation and coome back with the
 results...

 thanks
