What is TSC_ MHz?
TSC_MHz average MHz that the TSC ran during the entire interval. IRQ The number of interrupts serviced by that CPU during the measurement interval. The system total line is the sum of interrupts serviced across all CPUs.
How do you run a Turbostat?
There are two ways to invoke turbostat. The first method is to supply a command, which is forked and statistics are printed upon its completion. The second method is to omit the command, and turbostat displays statistics every 5 seconds. The 5-second interval can be changed using the –interval option.
What is Turbostat in Linux?
Turbostat is provided by the kernel-tools package. It reports on processor topology, frequency, idle power-state statistics, temperature, and power usage on Intel® 64 processors.
What is Rdmsr?
rdmsr is a tool used for reading a CPU’s machine specific registers (MSR). Note: if you’re running a Debian kernel, be sure that the msr. ko kernel module is loaded. ‘modprobe msr’ should do the trick.
What is TSC deadline timer?
TSC-Deadline mode Instead of using the CPU’s external/bus frequency to decrement a count, software sets a “deadline” and the local APIC generates a timer IRQ when the value of the CPU’s time stamp counter is greater than or equal to the deadline.
What is a Turbidostat used for?
The turbidostat is a continuous culture device in which the population density of an organism (or its food) is held constant, and the specific growth rate (r) of the population becomes a dependent variable. Turbidostat cultures are powerful tools for assessing biological limits on population growth.
What is MSR kernel?
From Wikipedia, the free encyclopedia. A model-specific register (MSR) is any of various control registers in the x86 instruction set used for debugging, program execution tracing, computer performance monitoring, and toggling certain CPU features.
How do I install MSR tools?
Detailed Instructions:
- Run update command to update package repositories and get latest package information.
- Run the install command with -y flag to quickly install the packages and dependencies. sudo apt-get install -y msr-tools.
- Check the system logs to confirm that there are no related errors.
What is Rdtsc instruction?
Description. The rdtsc (Read Time-Stamp Counter) instruction is used to determine how many CPU ticks took place since the processor was reset. Loads the current value of the processor’s time-stamp counter into the EDX:EAX registers. It is commonly used as a timing defense (anti-debugging technique).
What is difference between chemostat and turbidostat?
A chemostat refers to a system in which the chemical composition is kept at a controlled level for the culture of microorganisms while a turbidostat refers to a continuous microbiological culture device, which has feedback between the turbidity of the culture vessel and the dilution rate.
