substantial computing capability.

Researchers from the University of California, San Diego, have now partnered with Google to investigate whether retired Pixel devices can be repurposed
for practical computing workloads. The project aims to reduce waste while easing some demand for new hardware used in smaller-scale data centers . Latest Videos From Watch full video here: Researchers turn retired
smartphones into computing clusters Google Research says retired mobile devices contribute to the embodied carbon associated with manufacturing and the broader environmental cost of consumer electronics.

Rather than allowing those devices to remain unused, the research team converted older Pixel smartphones into what it describes as a general-purpose computing platform.

The approach involves removing components unnecessary for computing
workloads, including displays, batteries, cameras, speakers, and outer casings.

Only the motherboard remains because it contains the system-on-chip required for processing tasks and application execution. Are you a pro?

The researchers then replace Android with a Linux-based operating system commonly used in data centers, allowing deployment of orchestration platforms such as Kubernetes.

This process removes software overhead associated with consumer devices while enabling management tools normally found in enterprise environments.

The researchers claim that phones released only three years ago still delivered stronger single-core benchmark performance than some server configurations. What to read next Google's $3 kit aims to save your old Windows 10 laptop from the scrapheap Google and SpaceX are reportedly in

They compared those devices against systems such as the Asus RS720A-E11,
which can be configured with Nvidia H200 or Nvidia RTX Pro 6000 GPUs
alongside two AMD EPYC processors .

Although those server platforms remain significantly more powerful overall, the results suggested that older mobile hardware still retains useful computing value.

Testing further indicated that between 25 and 50 retired smartphones could provide computing capability comparable to a single dual-socket server-class processor.

However, the key question is not whether old smartphones can outperform
modern servers, but whether they can deliver useful computing capacity at a significantly lower cost. Local data centers could reduce costs for universities The research revealed that a cluster containing 20 smartphones could support an application used by a class of more than 75 students.

Instead of relying on cloud infrastructure, institutions could operate applications locally using repurposed devices already available in storage or recycling programs.

The team plans to assemble a facility using approximately 2,000 smartphones capable of supporting around 100 classes simultaneously.

They argue that the approach could provide educational institutions with computing resources at a fraction of the cost of building traditional infrastructure.

Rising prices for memory and storage components have increased the expense of deploying new systems.

This makes alternative approaches more attractive for budget-constrained organizations.

This is not the first attempt to give older mobile devices a second life, as previous studies explored using phones for monitoring systems and other computing tasks .

Even NASA repurposed the Qualcomm 801 processor, originally introduced in 2014, for navigation functions associated with the Ingenuity Mars helicopter and the Perseverance mission.

The research team expects to launch the full platform later this year while evaluating how consumer-grade hardware withstands continuous operation in a data center environment.
