[gradsusr] Future of GRADS

[mike at weatherwatch.net.au]

Hi all,

 

Just wondering what the future of GRADS is at all, the last update for it
was 2019 and with GRIB data getting more and more high res and larger, GRADS
is getting left behind significantly in terms of performance.. I've got
cases now with Australian BOM ACCESS data where it can take up to 10s to
generate an image due to how high res it is thanks to GRADS being single
threaded.  

 

To overcome this, I used a "workaround" for most charts which involves
segmenting a single chart into a 3x3 grid, getting grads to execute all 9
instances in parallel and then stitch the resulting panels together in a
final image. problem is that it just doesn't look "quite right" especially
when contouring is involved.  This is the only way I can get huge data to
load up quickly.  What is everyone else using these days to handle huge GRIB
files that can generate charts quickly using multithreading? (needs to be
able to run in a headless linux environment - no GUI at all, which is why
GRADS was perfect at the time). 

 

Cheers, Mike
