For old dominion research computing infrastructure and platform teams

Old Dominion Research Computing: cloud provisioning, image drift or worker startup?

Connect the first useful exception with the relevant runtime evidence. Did the cloud node become ready before the containerized worker launched?

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 one incident your team already resolved with the first failure, cited evidence and remaining questions. Did the cloud node become ready before the containerized worker launched? Only assign a rank, device or safe recovery state when the submitted evidence establishes it.

Did the cloud node become ready before the containerized worker launched?

Evidence to compare: Waterfield provisioning event, image or environment revision and first startup exception.

A cloud-capacity failure precedes application execution, while changing packages can break a previously working environment. Preserve that timeline before escalating a hardware incident.

Did the container expose the expected runtime and device?

Evidence to compare: Container image revision, device visibility and first library initialization error.

Host and container environments can differ. Confirm the failing process context before interpreting a missing library or unavailable device as a hardware fault.

Did artifact writing complete before storage filled?

Evidence to compare: Approved output path, quota result and the saved-artifact writer completion.

A full filesystem can invalidate the latest save even when training reached its final step. The existence of a filename does not establish a complete recovery checkpoint.

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
