Hi everybody,
I recently wrote a GX that involves several
GridTrnd() and GridWind(); operations. My problem that I would like to find
a solution to is that the GX involes several(on the order of 100)
iterations of GridTrnd_IMU(), GridBool_IMU(), GridWind_IMU(); etc. Each
iteration is performed in a loop structure. The GX takes a long time in GX
terms(on the order of 45sec-2min) even for a small input grid. I'm just
wondering if anybody can give a idea on how I could speed things
up.
I'm creating IMG objects for the grids I'm using. I
tried creating the IMG objects in memory(i.e. with CreateMem_IMG) but then
when I used GridBool to combine IMG1 and IMG2(where both IMG's are created in
memory) into a resultant "temp" grid, "temp.grd" was empty. Am I not using the
CreateMem() function properly?
I think the biggest problem slowing me down is that some of these
functions seem to have their own progress bar built internally into the
function. Is there any way I can overide this or eliminate the
progess bar. I tried doing it by SetInteractive_SYS(0) and Progress_SYS(0) but I
haven't got this to work.
I also found I have to create and destroy some IMG
objects in each loop. I've found that if I create an IMG object, IMG1(where IMG1
is READWRITE and is tied to a grid named "out.grd") and
then use,
GridWind_IMU(IMG1, "out.grd", IMU_WIND_GRID,
rMin, rMax, ...)
I get an error message that out.grd cannot be
accessed. Am I not doing something right here?
