Do the validation work
before you pay for the cluster.
For researchers who need to develop, check, and de-risk a method before spending HPC budget, queue time, and an allocation grant. Run real validated engines in the browser - the Blasius boundary layer to 0.4696, GW150914 to 0.13%, a trust verdict on every result - with no install and no queue, then take the validated setup to HPC for the production run. GDBS is the honest front end to the cluster, not a replacement for it.
