The SPARC64-VI processor has 2 cores with 2 threads each.
So 4 physical processors are 8 cores and 16 threads.

2. Shell Programming and Scripting
I wrote a very simple script that matches combinations of alphabetic characters (1-5). I want to use it to test CPU speeds of different hardware/platforms. The problem is that on multi-core/processor systems, only one CPU is being utilized to execute the script. Is there a way to change that?... (16 Replies)

Hi
on multi-core system - I know I can set each process to run on specific core (Processor Affinity).
If I want to set process (which contains several threads) to run on group of core, how can I do it ?
For example:
If we have 8 core,
and two process each process contain 4 threads.
And I... (2 Replies)

hostinfo
hostinfo(8) BSD System Manager's Manual hostinfo(8)
NAME
hostinfo -- host information
SYNOPSIS
hostinfo
DESCRIPTION
The hostinfo command displays information about the host system on which the command is executing. The output includes a kernel version
description, processor configuration data, available physical memory, and various scheduling statistics.
OPTIONS
There are no options.
DISPLAY
Mach kernel version:
The version string compiled into the kernel executing on the host system.
Processor Configuration:
The maximum possible processors for which the kernel is configured, followed by the number of physical and logical processors avail-
able.
Note: on Intel architectures, physical processors are referred to as cores, and logical processors are referred to as hardware threads;
there may be multiple logical processors per core and multiple cores per processor package. This command does not report the number of
processor packages.
Processor type:
The host's processor type and subtype.
Processor active:
A list of active processors on the host system. Active processors are members of a processor set and are ready to dispatch threads.
On a single processor system, the active processor, is processor 0.
Primary memory available:
The amount of physical memory that is configured for use on the host system.
Default processor set:
Displays the number of tasks currently assigned to the host processor set, the number of threads currently assigned to the host proces-
sor set, and the number of processors included in the host processor set.
Load average:
Measures the average number of threads in the run queue.
Mach factor:
A variant of the load average which measures the processing resources available to a new thread. Mach factor is based on the number of
CPUs divided by (1 + the number of runnablethreads) or the number of CPUs minus the number of runnable threads when the number of
runnable threads is less than the number of CPUs. The closer the Mach factor value is to zero, the higher the load. On an idle system
with a fixed number of active processors, the mach factor will be equal to the number of CPUs.
