[Hpc-notice] netcdf emergency upgrade

[Paul Van Der Mark]

Dear RCC users,

During our recent maintenance period, we upgraded our netcdf
installation to 4.6.2 (4.4.4 for the Fortran and 4.2 for the C++
extensions). It turns out that a number of issues exists with the 4.6.2
release, including potential runtime errors while using the library.
These errors where identified by the netcdf team and we were
recommended to upgrade to netcdf version 4.7.0 as soon as possible.

We have tested this version on our test cluster and we will start
pushing out these newer versions to the cluster this afternoon. All
nodes will have these newer versions between now and 6PM.

*If you are using the netcdf libraries, you will encounter issues with
your program if your program is in the queue but not running
yet. Please recompile your program. *

You can find out which version of netcdf is install on a node/login
node if you run the nc-config and nf-config tools from either the
command line or script. 

[paulvdm at hpc-login-vm1 ~]$ nc-config --version
netCDF 4.6.2
[paulvdm at hpc-login-vm1 ~]$ nf-config --version
netCDF-Fortran 4.4.4

These will show 4.7.0 and 4.4.5 when the upgrade are installed.

We have a number of packages that depend on netcfd and they will/have
been upgrade to use the newer netcdf libraries.

Our apologies for this inconvenience.

Best regards,
The RCC Team
