was richly deserved and proof of that prescience. GrADS made my own M.S. degree more feasible by facilitating writing a SkewT script for it in only a few days in 1996, which is still, remarkably, heavily used today -- and GrADS has made so much on websites
here at FSU for 21 years (and eight years before that at PSU). </span></div>

<p class="x_MsoNormal"><span style="font-size:11.0pt">To add a little context, GrADS was supported by US federal agencies as part of a multi-agency, block grant to COLA over a period of a quarter century (1993-2019). No grant or other funds for GrADS have been
available since that time, and, at present, nobody is paid to support/develop GrADS. Maintenance and support of the software and user community is on a volunteer basis, notably by Jennifer Adams, as well as by respondents to the GrADS User Forum. GrADS continues
to meet the needs of thousands of users worldwide (including me), in both academic and operational use cases; however, as noted in this thread, the limitations of the code are becoming increasingly apparent as data sets grow and analytics become more complex.
The development undertaken near the end of the funding period was intended to enable GrADS usage in conjunction with other codes, including Python (as Jennifer noted) and GIS applications, so some workarounds are possible. Others who have encountered limitations
and have found solutions are welcome to respond to this thread. </span></p>

I am doing my best to support existing features in both packages during my spare time or when required for operational support at GES DISC. I continue to use GrADS almost every day, but I think it's safe to say that rewriting the GrADS I/O layer to support
multithreading is unlikely. The recent additions to the python interface (GradsPy) allow users to leverage Python for I/O and do analysis and plotting with GrADS, or the reverse -- GrADS does the I/O and Python does the analysis and plotting. The get() and
put() methods allow you to pass defined variables back and forth. Maybe those features can help you build a better workaround.<br>

<p class="x_MsoNormal" style="margin-left:.5in"><span lang="EN-AU" style="font-size:11.0pt">Hi all,</span></p>
<p class="x_MsoNormal" style="margin-left:.5in"><span lang="EN-AU" style="font-size:11.0pt"> </span></p>
<p class="x_MsoNormal" style="margin-left:.5in"><span lang="EN-AU" style="font-size:11.0pt">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.
</span></p>
<p class="x_MsoNormal" style="margin-left:.5in"><span lang="EN-AU" style="font-size:11.0pt"> </span></p>
<p class="x_MsoNormal" style="margin-left:.5in"><span lang="EN-AU" style="font-size:11.0pt">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).
