India in Moscow on Sunday, Beijing on Monday India's foreign minister was in Moscow on Monday. Its national security adviser was in Beijing that same morning, and the twelve months behind both trips explain them better than either does alone. southasianherald.com/india-i… @imrahulpawa @MEAIndia @DrSJaishankar #SJaishankar #IndiaRussia #IndiaRussiaRelations #IRIGCTEC

How the U.S. Air Force Turned PlayStations into a Supercomputer In the late 2000s, deep inside the Air Force Research Laboratory (AFRL) in Rome, New York, a small team of engineers stared at a familiar problem: the Department of Defense desperately needed massive computing power for real-world defense work: processing high-definition satellite imagery, enhancing radar signals, spotting patterns in intelligence data, and experimenting with early artificial intelligence. Traditional supercomputers could do the job, but they came with a brutal price tag: tens of millions of dollars, sky-high energy bills, and months of procurement red tape. Budgets were tight. Time was shorter. Then Mark Barnell, director of high-performance computing at AFRL, had a spark of genius that sounded almost like a joke around the water cooler: What if we used Sony PlayStation 3s? The idea wasn’t as crazy as it sounded. The PS3, released in 2006, hid a technological marvel inside its sleek black case: the Cell Broadband Engine processor, co-designed by Sony, Toshiba, and IBM. This wasn’t just a gaming chip; it packed seven high-speed “synergistic processing elements” (SPEs) that excelled at the exact kind of parallel, vectorized calculations needed for scientific workloads. Even better, Sony had built in an “Other OS” feature that let users install Linux. The consoles were cheap (around $400 each on the military’s bulk-buy discount), power-efficient, and already mass-produced by the millions thanks to the gaming market. Comparable specialized hardware would have cost $10,000 per unit. Barnell and his team started small around 2006–2008, buying a handful of PS3s, ripping out the game discs, installing Linux, and clustering them together. The results were astonishing. Early experiments proved the consoles could handle heavy scientific computing far better than anyone outside the lab expected. They published the first glimpse of their breakthrough in a technical paper on algorithm optimizations for PS3 clusters. Emboldened, they scaled up. By November 2010, they had assembled the Condor Cluster: 1,760 PlayStation 3 consoles (some counts cite 1,716 as the exact core), networked with 168 GPUs and 84 coordinating servers running dual quad-core Intel Xeons. The final machine delivered a blistering 500 teraflops (500 trillion floating-point operations per second). It ranked as the 33rd fastest supercomputer on the planet and the fastest *interactive* computer in the entire Department of Defense. Total cost? Roughly $2 million: about one-tenth of what a traditional system would have demanded. Power consumption? A mere fraction of the energy a conventional supercomputer would gulp down. The creativity was off the charts. This wasn’t just thriftiness; it was pure hacker ingenuity applied at the highest levels of national security. Instead of waiting for billion-dollar custom hardware, the team looked at the consumer electronics aisle and saw a supercomputer in disguise. They turned gaming consoles: devices meant for Call of Duty marathons into a classified workhorse for analyzing spy-plane imagery, optimizing synthetic aperture radar, and exploring neuromorphic “computational intelligence.” It was MacGyver meets Manhattan Project: resourceful, playful, and brilliantly subversive. Engineers joked that the PlayStations were “the only supercomputer you could buy at Best Buy.” The Condor Cluster ran for years, delivering mission-critical insights until it was decommissioned around 2015. Sony later patched out the “Other OS” feature in a firmware update, but the Air Force already had its fleet safely locked away. The project proved that sometimes the most powerful weapons aren’t built in secret labs: they’re bought off the shelf and reimagined.
