Not included with the wgrib2 source code could cause a seg-fault. Jasper library, then your copy of wgrib2 may be vunerable to this If your copy of wgrib2 is using another version of the

Problem was fixed with an Ubuntu/Debian update to Jasper (fall 2015) which was The jpeg2000 library (Jasper) could seg-fault with larger grids. The common problemsĪre in related to experimental/alpha features and the following 3 problems. Seg-faults are pretty uncommon to wgrib2. Wgrib2 is used in NCEP operations and by many daily processing jobsĪt CPC. Use one of those programs if you want support. There are many other programs that can handle grib and NetCDF4.

Long-term problems with the hdf5 library. Wgrib2 with netCDF4 support by changing the makefile.Ĩ/2020: NetCDF4 remains on the unsupported feature list because of To make hdf5-1.10.4 work (needed for netCDF4).

Wgrib2 can be configured with (1) no NetCDF support, (2) NetCDF3 support or The Laffer curve for the number of threads. So the optimal number of cores is determined by the equivalent of the Is reduced which means more reading of the DRAM.

More threads means the effective size of the cache per active thread (Use the clock cycles spent waiting for reading the DRAM.) However,

Hyper-threading would seem to be a good idea. The second line tells OpenMP to release unused threads (cores)įor a 4-core/8-thread CPU (Xeon(R) W-2123), taking advantage of The first line limits OpenMP to three threads (cores) Usually I set the number to 3 onĪ 4-core/4-thread machine. In general, you set the number of threads to be less or equal With gcc, clang and icc, OpenMP is on by default. OpenMP is used to speed up wgrib2 by running loops over

parallel processing by flow-based programming.

This kitchen miracle was done by a more developer friendly designĪnd the contributions of many people. wgrib2 is more like fourĭrawers of kitchen utensils as well as the microwave and blender.
