[GRASS-user] Global overview of GRASS HPC resources/installations ?

[Laura Poggio]

I am really interested in this. I am experimenting with different settings
to use GRASS on HPC, more specifically on multi-core local machines and on
single-core multiple instances on a cloud provider. It would be great to
share experiences with other people fighting the same problems.

Thanks

Laura
