For gmi cloud infrastructure and model engineering teams

GMI Cloud worker failed: managed cluster, container or bare metal?

Identify the compute product and first runtime exception before escalating a serving or training incident. Keep API symptoms separate from evidence available at the actual worker.

Replay a resolved GMI Cloud workflow incident

Upload your log file. Review the selected evidence and masking, then run diagnosis. Keep the original log for any follow-up questions.

Before uploading, review cloud data handling and local options.

Start your free 30-day Team evaluation

Up to 50 diagnoses a day for 30 days. Verify your work email to activate an eligible company evaluation, then replay a resolved incident and compare the evidence and next steps with your team's confirmed cause.

Use your company email (e.g. alex@yourcompany.com). Eligible company domains can activate a free 30-day Team evaluation (up to 50 diagnoses/day) after email and domain checks, regardless of mail host. Uncertain domains can request review from support@denpex.com. Free local diagnoses remain available without an account.

What a useful evaluation should establish

Compare the first failure, quoted evidence and unresolved questions with an incident your team has already resolved. Begin with this question: Which compute product ran the workload? Only attribute a process, rank, device or recovery state when the submitted evidence establishes it.

Which compute product ran the workload?

Evidence to compare: Managed-cluster, container or bare-metal identity and the launch result.

The support and access boundary changes by product. Establish it before requesting host telemetry or recommending an intervention.

Did model initialization precede the request failure?

Evidence to compare: Worker startup milestones, model revision and the first exception.

A client-facing error can follow a loading failure. Preserve that earlier operation without inferring a specific serving engine from the API alone.

What evidence can the next owner access?

Evidence to compare: Approved worker identifiers, relevant orchestration events and available host logs.

A useful escalation states which layer is observed and which is not. Missing host visibility remains a limitation rather than a guessed GPU diagnosis.

Use Denpex alongside your existing telemetry tools to investigate submitted incident evidence. With monitoring configured on a supported plan, detected failures can trigger alerts and an automatic diagnosis from the captured evidence.

Inside Denpex

See the evidence, not just the claim

Follow the causal chain, inspect the quoted evidence and prepare the next handoff. These actual product captures use founder-account examples and the VS Code extension, with the source identified under each image. Open a capture to inspect it at full size.

Follow the failure through the cascade

Denpex founder-account example: a causal graph connects an Xid 48 ECC event to a rank exit and downstream collective failures, with quoted evidence for each stage.
Live founder-account capture from the bundled NCCL/ECC example. Follow the hardware event, rank exit and downstream symptoms with a supporting log quote at each stage.Inspect original image

Prepare the hardware escalation

Denpex hardware handoff summary asks the operator to capture diagnostic evidence and verify RMA eligibility with the vendor.

Ask for the evidence that is missing

Denpex historical example says a collective timeout does not establish the initiating rank, cause or failure domain and requests distinguishing evidence before a remedy.

Keep the investigation in the editor
