The following is extracted from the v8 documentation. Before-image I/O Before-imaging is always enabled to let PROGRESS recover transactions if the system fails. This mechanism is extremely important for database reliability, but it creates a significant amount of I/O that can affect performance. In addition, before-image I/O is usually the first and most likely cause… Leer más »

FIO is an I/O tool meant to be used both for benchmark and stress/hardware verification. It has support for 13 different types of I/O engines (sync, mmap, libaio, posixaio, SG v3, splice, null, network, syslet, guasi, solarisaio, and more), I/O priorities (for newer Linux kernels), rate I/O, forked or threaded jobs, and much more. It… Leer más »

Un magnetar o magnetoestrella es una estrella de neutrones alimentada con un campo magnético extremadamente fuerte. Se trata de una variedad de púlsar cuya característica principal es la expulsión, en un breve período (equivalente a la duración de un relámpago), de enormes cantidades de alta energía en forma de rayos X y rayos gamma. Los… Leer más »
Metallic hydrogen is a state of hydrogen in which it behaves as an electrical conductor. This state was predicted theoretically in 1935, but has not been reliably produced in laboratory experiments due to the requirement of high pressures, on the order of hundreds of gigapascals. At these pressures, hydrogen might exist as a liquid rather… Leer más »
