Kyoto University Loses 77 Terabytes of Research Data After Supercomputer Backup Error
Unfortunately, some of the data is lost forever. đ§
#engineering
A routine backup procedure meant to safeguard data of researchers at Kyoto University in Japan went awry and deleted 77 terabytes of data, Gizmodo reported. The incident occurred between December 14 and 16, first came to light on the 16th, and affected as many as 14 research groups at the university.
Supercomputers are the ultimate computing devices available to researchers as they try to answer complex questions on a range of topics from molecular modeling to oil exploration, climate change models to quantum mechanics, to name a few. Capable of making hundred quadrillion operations a second, these computers are not only expensive to build but also to operate, costing hundreds of dollars for every hour of operation.
According to Bleeping Computer that originally reported the mishap, the university uses Cray supercomputers with the top system employing 122,400 computing cores. The memory on the system though is limited to approximately 197 terabytes and therefore, an Exascaler data storage system is used, which can transfer 150 GB of data per second and store up to 24 petabytes of information.
Navyâs Costly Carrier Finally Has Its Bomb-Lifting Elevators
The Navyâs costliest warship finally has all the elevators needed to lift bombs from below its deck so it can deploy on its first operational patrol â more than four and a half years after delivery.
The service has announced that the 11th and final Advanced Weapons Elevator is in place on the $13.3 billion USS Gerald R. Ford and the aircraft carrier is ready for training and operations.
âThis is a significant milestone for the Navy, ship and her crew,â Rear Admiral James Downey, the Navyâs program executive officer for aircraft carriers, said in a statement. âWe now have the entire system to operate and train with.â He said the service and the prime contractor, Huntington Ingalls Industries Inc., used âhundreds of craftsmen, technicians and engineers, working around the clock âthrough multiple underway and holiday periods â to get these advanced systems on line and operational.â
Raytheon To Enhance Seasparrow Missiles For US Navy That Can Defend NATO Vessels Against Missile & Drone Attacks
Defense company Raytheon has clinched a US Navy contract to provide engineering and technical services for the Evolved Seasparrow Missile and NATO Seasparrow Missile programs, the Pentagon has said.
A press release by the Department of Defense on December 30 stated, âRaytheon Company [of] Tucson, Arizona, is awarded a $55,121,826 modification to a previously awarded contract for engineering and technical services in support of the Evolved Seasparrow Missile and NATO Seasparrow Missile Systems programs.â
The contract combines purchases for the US government (99%); and those of Japan and the United Arab Emirates (1%) under the Foreign Military Sales program.
Scotland missed 100% clean electricity consumption in 2020
In 2011, Scotland set a target of reaching 100% clean electricity consumption in 2020. And last year, the country almost reached its target â 98.6% of gross electricity consumption came from renewable sources, according to the Scottish governmentâs December energy statement.
