Large ram usage for dispersion backward models
I am running backwards dispersion models on a Linux server, using 0.25 degree GFS weather data with 1e6 particles with a simulation time of between 5 and 10 days. These simulations max out at 15GB ram memory usage per core, even if a parallelized version of HYSPLIT is used. When looking closer at ...
