The Hidden Costs of 'I Don't Know When It Will Run'

Hidden Cost Analysis

When we talk about GPU efficiency, we usually focus on utilization metrics. How many GPUs are running? What's our average utilization? Are we leaving compute on the table?

These metrics matter. But they miss the hidden costs of queue uncertainty—the ones that don't show up in your monitoring dashboards but absolutely show up in your team's productivity, morale, and output.

Cost #1: Engineer Time

The most expensive resource in most AI teams isn't GPUs—it's engineers. Senior ML engineers cost $300K-500K+ fully loaded. Their time is precious.

When queues are unpredictable, engineers develop coping mechanisms:

Checking status every 10 minutes (or more)
Submitting duplicate jobs 'just in case'
Working odd hours to avoid peak queues
Over-requesting resources to avoid requeuing
Context-switching between tasks while waiting

Each of these destroys productivity. An engineer who's constantly checking job status isn't doing deep work. An engineer who's working at 2 AM isn't going to be sharp the next day.

The Math

If queue uncertainty causes each engineer to lose just 1 hour per day to status checking and context-switching, that's 250 hours per year per engineer. At $200/hour fully loaded, that's $50K per engineer annually—just from uncertainty.

Cost #2: Experiment Velocity

ML is fundamentally an iterative process. The team that runs more experiments, learns faster, and ships better products. Experiment velocity is a competitive advantage.

Queue uncertainty directly kills velocity. When you don't know when results will come:

You can't plan next steps

"I'll decide what to do next when I see the results" leads to dead time.

Teams become conservative

"I won't try that ambitious experiment because the queue risk is too high."

Feedback loops slow down

The time between "I have an idea" and "I know if it works" expands.

Context gets lost

By the time results come, you've forgotten what you were testing.

Cost #3: Team Morale

Nothing erodes trust faster than uncertainty. When someone asks "when will my job run?" and the answer is "I don't know," frustration builds.

I feel like I'm fighting the system every day. It shouldn't be this hard to just run an experiment.

This frustration spreads. Engineers blame platform teams. Platform teams feel unfairly blamed. Leadership loses confidence in timelines. The whole organization suffers from a problem nobody can point to directly.

Cost #4: Bad Decisions

Without visibility, every infrastructure decision becomes a guess.

"Queues are too long" usually leads to "we need more GPUs." But without visibility data, you can't answer the real questions:

  • Are queues long because of capacity, or because of scheduling patterns?
  • Would adding GPUs actually reduce wait times, or would they just get absorbed?
  • Are some teams over-requesting resources at others' expense?
  • What would happen if we changed scheduling policies?

Without data, you might buy $500K in GPUs that don't solve the actual problem.

The Solution Isn't More GPUs

Throwing hardware at the problem rarely works. If the issue is visibility, more capacity just means more capacity to be uncertain about.

The solution is visibility: knowing what's happening so everyone can make better decisions. When teams can see queue patterns, they optimize naturally—no process changes required.

Ready to eliminate uncertainty?

We're building visibility into GPU scheduling. Let's talk about what that could mean for your team.
