Dear Jeff, Thanks a lot for your reply. I think it might be related with the memory management on our sever. But anyway, as you suggested, I open an issue on netcdf4-python.google.co <http://netcdf4-python.google.com>m. you can find the data and script on ftp://ftp.cea.fr/incoming/y2k01/chaoyue/. The cal_cmi_big.py gave the core dumped error, in which I tried to operate with big files (~2G). The cal_cmi_small.py works fine, which handles data only ~25M (a subset of big files). I used a small function (which use NetCDF4) in the script to read and write nc data with NetCDF4. You can also find this function in ncfunc.py. I tested all the script and data before I upload on our ftp.
thanks again for your help, cheers, Chao 2012/5/26 Jeff Whitaker <jsw...@fastmail.fm> > On 5/26/12 5:51 AM, Chao YUE wrote: > > Dear all, > > Previously I am able to run a script on our server but now it gave me a > Segmentation fault (core dumped) error. > try I tried the script with same type of netcdf file but with much smaller > file size and it works.
