Benchmark (computing)

 

Introduction:

In computing, a benchmark is the act of running a computer
program, a set of programs, or other operations, in order to assess the
relative performance of an object, normally by running a number of standard
tests and trials against it. The term ‘benchmark’ is also mostly utilized for
the purposes of elaborately designed benchmarking programs themselves.
Benchmarking is usually associated with assessing performance characteristics
of computer hardware, for example, the floating point operation performance of
a CPU, but there are circumstances when the technique is also applicable to
software. Software benchmarks are, for example, run against compilers or
database management systems. Benchmarks provide a method of comparing the
performance of various subsystems across different chip/system architectures.
Test suites are a type of system intended to assess the correctness of
software.

Why Would You Run a Benchmark?

You might run a benchmark to simply compare your hardware
with someone else’s, to test that new hardware is actually performing as
advertised, or to see if a piece of hardware supports a certain amount of
workload.

For example, if you plan on installing a new high-end video
game on your computer, you might run a benchmark to see if your hardware is
capable of running the game. The benchmark will apply a particular amount of
stress (which is supposedly close to what is required for the game to run) on
the hardware in question to check that it can actually support the game.

Benchmarking your network to check the available bandwidth
might be useful if you suspect that you’re not getting the internet speeds that
your ISP has promised.

It’s most common to benchmark computer hardware like a CPU,
the memory (RAM), or a video card. Hardware reviews you find online almost
always include benchmarks as a way to objectively compare one make and model of
video card, for example, with another.

How to Run a Benchmark

There’s a variety of free benchmark software tools that can
be used to test various hardware components.

Novabench is one free benchmarking tool for Windows and Mac
for testing the CPU, hard drive, RAM, and video card. It even has a results
page that lets you compare your NovaBench Score with other users.

Things to Remember About Benchmarks

It’s important to make sure you aren’t doing a bunch of
other things at the same time that you’re running a benchmark. So, for example,
if you’re going to run a benchmark on your hard drive, you don’t want to also
be using the drive unnecessarily, like copying a bunch of files to and from a
flash drive, burning a DVD, etc.

There seems to be lots of concern as to the reliability of
benchmarking, like the fact that some manufacturers may be unfairly rating
their own products better than their competition. There’s a surprisingly large
list of these "challenges" to benchmarking on Wikipedia.

Is a Stress Test the Same Thing as a Benchmark?

The two are similar, but a stress test and a benchmark are
two different terms for good reason. While a benchmark is used to compare
performance, a stress test is for seeing just how much can be done to something
before it breaks.

 

Types of benchmark

 

1.            Real
program

•             word
processing software

•             tool
software of CAD

•             user’s
application software (i.e.: MIS)

 

2.            Component
Benchmark / Micro benchmark

•             core
routine consists of a relatively small and specific piece of code.

•             measure
performance of a computer’s basic components 4

•             may be used
for automatic detection of computer’s hardware parameters like number of
registers, cache size, memory latency, etc.

 

3.            Kernel

•             contains
key codes

•             normally
abstracted from actual program

•             popular
kernel: Livermore loop

•             linpack
benchmark (contains basic linear algebra subroutine written in FORTRAN
language)

•             results
are represented in MFLOPS

4.            Synthetic
Benchmark

•             Procedure
for programming synthetic benchmark:

•             take
statistics of all types of operations from many application programs

•             get
proportion of each operation

•             write
program based on the proportion above

•             Types of
Synthetic Benchmark are:

•             Whetstone

•             Dhrystone

•             These
were the first general purpose industry standard computer benchmarks. They do
not necessarily obtain high scores on modern pipelined computers.

 

5.            I/O
benchmarks

6.            Database
benchmarks: to measure the throughput and response times of database management
systems (DBMS’)

7.            Parallel
benchmarks: used on machines with multiple cores, processors or systems
consisting of multiple machines

Benchmark (computing)

 

introduction:

In computing, a benchmark is the act of walking a laptop
program, a fixed of programs, or other operations, so one can check the
relative overall performance of an item, commonly with the aid of jogging some
of preferred exams and trials towards it. The term ‘benchmark’ is likewise
commonly applied for the functions of elaborately designed benchmarking
programs themselves. Benchmarking is usually related to assessing performance
characteristics of pc hardware, as an example, the floating point operation
overall performance of a CPU, however there are instances whilst the method is
likewise applicable to software program. software program benchmarks are, for instance,
run against compilers or database control systems. Benchmarks offer a technique
of evaluating the performance of various subsystems throughout specific
chip/machine architectures. check suites are a kind of gadget supposed to
evaluate the correctness of software program.

Why might You Run a Benchmark?

you might run a benchmark to clearly examine your hardware
with someone else’s, to test that new hardware is really performing as
marketed, or to peer if a bit of hardware helps a sure amount of workload.

for example, if you plan on putting in a brand new high-give
up online game for your computer, you would possibly run a benchmark to peer in
case your hardware is able to running the game. The benchmark will practice a
particular amount of strain (that’s supposedly close to what’s required for the
sport to run) at the hardware in question to check that it could definitely
support the game.

Benchmarking your network to check the to be had bandwidth
might be useful in case you suspect which you’re no longer getting the net
speeds that your ISP has promised.

it is maximum not unusual to benchmark computer hardware
like a CPU, the reminiscence (RAM), or a video card. hardware opinions you
locate on line nearly constantly consist of benchmarks as a manner to
objectively compare one make and version of video card, for example, with
another.

the way to Run a Benchmark

there’s a variety of unfastened benchmark software program
tools that can be used to check diverse hardware components.

Novabench is one loose benchmarking device for windows and
Mac for trying out the CPU, difficult pressure, RAM, and video card. It even
has a results page that lets you compare your NovaBench rating with other
users.

things to keep in mind about Benchmarks

it’s vital to ensure you aren’t doing a group of other
matters at the same time that you’re running a benchmark. So, as an example, if
you’re going to run a benchmark on your difficult pressure, you do not want to
also be using the power unnecessarily, like copying a bunch of documents to and
from a flash drive, burning a DVD, and so on.

There seems to be lots of challenge as to the reliability of
benchmarking, just like the reality that a few manufacturers may be unfairly
score their very own products better than their opposition. there may be a
notably big list of those “demanding situations” to benchmarking on
Wikipedia.

Is a stress test the identical thing as a Benchmark?

the 2 are comparable, but a strain check and a benchmark
are  one-of-a-kind phrases for proper
reason. at the same time as a benchmark is used to compare performance, a
pressure test is for seeing just how a good deal may be performed to some thing
before it breaks.

computers.
