[Users] Compilation Error in cluster ParamGanga

[Shamim Haque 1910511]

Dear Frank,

I added the alias pattern for the computing nodes and now ETK can detect
the cluster (checked by asking "whoami") during the batch queuing. I'll get
in touch with the admins to include 'patch'.

However, the problem still persists, having assured that the correct
machine file and option list are being used during the compilation.
