Re: [gembud] Generating NEXRAD radar imagery with gpmap_gf


Are you using the original compressed level III products, or are you piping them through ucnids to uncompress them? I had a similar problem to this using nex2gini in GEMPAK 6.2. Occasionally the ucnids uncompressed products would be corrupt somehow and cause the nex2gini program to just hang. Eventually my system would hang with many, many hung gempak processes.

I changed my setup so I am now just saving the level III files in their compressed format and letting GEMPAK uncompress, so far no problems.

Not sure if this is your problem, but figured I'd throw it out there.

Does anyone generate a lot of individual NEXRAD level III products with gpmap_gf? I'm trying to generate real-time plots of NOQ Reflectivity and NOU Velocity from 30 radars in the midwest and its crashing my server after a few hours, even when I only run 3 plots at a time. I'm running GEMPAK6.4.0 on a RHEL 6 machine with 64 GB of memory. I'm wondering what I'm doing wrong and if someone has a better way of doing this.

crashing your server, how? Exhausting memory? kernic panic? Are the processes not going away once running them? How are you running them?
