WebFeb 23, 2016 · If two bits are flipped in a word, ECC can detect that the word is corrupted, but cannot fix it. The study found that double-bit errors occurred about once every 24 hours in Jaguar’s 360 TB of memory. The surface area of all the silicon in a supercomputer functions somewhat like a large cosmic-ray detector.

Cosmic Ray Flips Bit, Assists Mario 64 Speedrunner

WebAs the video says, bit flips caused by cosmic rays do happen - constantly, in fact - but we only notice on the rare occasion that something unexpected happens as a result. For file storage I don't think it's anything to worry about, especially with the level of error correction that modern drives/computers are capable of. Energetic neutrons produced by cosmic rays may lose most of their kinetic energy and reach thermal equilibrium with their surroundings as they are scattered by materials. The resulting neutrons are simply referred to as thermal neutrons and have an average kinetic energy of about 25 millielectron-volts at 25 °C. See more In electronics and computing, a soft error is a type of error where a signal or datum is wrong. Errors may be caused by a defect, usually understood either to be a mistake in design or construction, or a broken component. A soft … See more Soft error mitigation A designer can attempt to minimize the rate of soft errors by judicious device design, choosing the right semiconductor, package and substrate materials, and the right device geometry. Often, however, this is limited by the … See more Soft error rate (SER) is the rate at which a device or system encounters or is predicted to encounter soft errors. It is typically expressed as either the number of failures-in-time (FIT) or mean time between failures (MTBF). The unit adopted for quantifying … See more Whether or not a circuit experiences a soft error depends on the energy of the incoming particle, the geometry of the impact, the location … See more Alpha particles from package decay Soft errors became widely known with the introduction of dynamic RAM in the 1970s.
