[RegCNET] Lateral Boundary Treatment (fwd)

[XUNQIANG BI]

Hi, Richard:

Which 64-bit CPU ? AMD64 or Intel 64 ?

I know the ../../Commons/env/liblinux64/libnetcdf.a works with
SGI Intel 64-bit Cluster, and ../../Commons/env/liblinuxamd64/libnetcdf.a
works with our AMD64 cluster (with pgf90).

Anyway, it seems to me that the netcdf library got from unidata is
always the best one. Can you try to find the right one from
http://www.unidata.ucar.edu/ ?

By the way, once you find the right one, could you please send me a copy?

Thanks and Regards,
Xunqiang Bi
