ProcDump is a command-line application used for monitoring an application for CPU spikes and creating crash dumps during a spike. [2] [3] The crash dumps can then be used by an administrator or software developer to determine the cause of the spike.
[45] [46] It affects certain ARM64 CPUs [47] and the following Intel CPU families: Cascade Lake, Ice Lake, Tiger Lake and Alder Lake. According to Linux kernel developers AMD CPUs are also affected. [48] In March 2022, a vulnerability affecting a wide range of AMD CPUs was disclosed under CVE-2021-26341. [49] [50]
time (Unix) - can be used to determine the run time of a program, separately counting user time vs. system time, and CPU time vs. clock time. [1] timem (Unix) - can be used to determine the wall-clock time, CPU time, and CPU utilization similar to time (Unix) but supports numerous extensions.
LINPACK was designed to help users estimate the time required by their systems to solve a problem using the LINPACK package, by extrapolating the performance results obtained by 23 different computers solving a matrix problem of size 100. This matrix size was chosen due to memory and CPU limitations at that time:
When a CPU wishes to send an interrupt to another CPU, it stores the interrupt vector and the identifier of the target's local APIC in the Interrupt Command Register (ICR) of its own local APIC. A message is then sent via the APIC bus to the target's local APIC, which then issues a corresponding interrupt to its own CPU.
The average of Cycles Per Instruction in a given process (CPI) is defined by the following weighted average: := () = () Where is the number of instructions for a given instruction type , is the clock-cycles for that instruction type and = is the total instruction count.
Luigi Mangione, the man accused of murdering UnitedHealthcare CEO Brian Thompson, was told "don't say a word" by his lawyer in court, following an outburst outside the hearing at a Pennsylvania ...
In computer security, a cold boot attack (or to a lesser extent, a platform reset attack) is a type of side channel attack in which an attacker with physical access to a computer performs a memory dump of a computer's random-access memory (RAM) by performing a hard reset of the target machine.
