Cause (Documented platform behavior): Triton checks each GPU against a minimum supported compute capability.
Fix status: documented_behavior

Problem details
- Observed symptom
- GPU model instances fail to load on the device.
- Context
- Product: NVIDIA Triton Inference Server Component: CUDA device check Operation: Running a recent Triton image on older GPUs (e.g. Pascal/Maxwell) Affected versions: unknown Environment: unknown Packages: tritonserver main at pinned SHA Trigger: Device compute capability below TRITON_MIN_COMPUTE_CAPABILITY / --min-supported-compute-capability.

solution · Revision 1
Proposed fix: [Triton] "gpu N has compute capability 'X.Y' which is less than the minimum supported of 'Z'" - model instances skip older GPUs
Recommended action: Use supported GPUs or an older Triton release; --min-supported-compute-capability can lower the check at your own risk.
