Probe compute environment
Use Wisp's environment Probe action. It performs bounded, read-only checks and
stores the result on the ExecutionContext. An SSH probe batches every check
into one authenticated session; do not replace it with an ad-hoc SSH discovery
loop. Batch SSH uses IdentitiesOnly=yes; users relying on a non-default
ssh-agent key must configure its IdentityFile in Wisp or SSH config.
After probing:
- Treat persisted capabilities as the server contract until it is probed again.
- Treat
gpu_summary: nullas no usable GPU. Plan CPU work and never add CUDA/GPU flags speculatively. - Treat
privilege: unprivilegedas no root or passwordless sudo. Do not usesudo, system package managers, or system paths; prefer user-space environments, modules, containers already installed by the administrator, or ask the user for an administrator-installed dependency. - Use a detected scheduler rather than running long work on a login node.
- Use the recorded interpreter paths and environment managers. Do not assume
python,Rscript, conda, mamba, or modulecmd exists when absent. - If the probe failed, inspect the saved error and ask the user to check the connection before manually probing again. Never loop or automatically retry an SSH probe. If it is merely stale relative to a server change, probe again before submitting work.
