MemTest86 and Memtest86+ are memory test software programs designed to test and stress test an x86 architecture computer's random-access memory (RAM) for errors, by writing test patterns to most memory addresses, reading back the data, and comparing for errors. [6]
Sysbench can run benchmark tests specified in command line flags or in shell scripts. The type of test to run is specified in the command options and would be one of: cpu: CPU performance test; fileio: File I/O test; memory: Memory speed test; mutex: Mutex performance test; threads: Threads subsystem performance test
A set of benchmarks allows you to test: memory read — tests the speed of data transfer from RAM to the processor. memory write — tests the speed of data transfer from the processor to RAM. memory copy — tests the speed of data transfer from one memory cell to another via the processor's cache.
Memory diagnostic software programs (e.g., memtest86) are low-cost or free tools used to check for memory failures on a PC. They are usually in the form of a bootable software distribution on a floppy disk or CD-ROM. The diagnostic tools provide memory test patterns which are able to test all system memory in a computer.
Puppy Linux 5.10 desktop running in RAM. This is a list of Linux distributions that can be run entirely from a computer's RAM, meaning that once the OS has been loaded to the RAM, the media it was loaded from can be completely removed, and the distribution will run the PC through the RAM only.
A light-weight Linux distribution a Linux distribution that uses lower memory and processor-speed requirements than a more "feature-rich" Linux distribution. The lower demands on hardware ideally result in a more responsive machine, and allow devices with fewer system resources (e.g. older or embedded hardware) to be used productively.
The idea behind tmpfs is similar in concept to a RAM disk, in that both provide a file system stored in volatile memory; however, the implementations are different. While tmpfs is implemented at the logical file system layer, a RAM disk is implemented at the physical file system layer. In other words, a RAM disk is a virtual block device with a ...
The gap between processor speed and main memory speed has grown exponentially. Until 2001–05, CPU speed, as measured by clock frequency, grew annually by 55%, whereas memory speed only grew by 7%. [1] This problem is known as the memory wall. The motivation for a cache and its hierarchy is to bridge this speed gap and overcome the memory wall.
