i am trying to find out hpw many virtual and physical processors does any linux machine has:
output of /proc/cpuinfo is as below :
using this info how can i figure out how many physical or virtual processor does any linux machine has...is der any better way to find out or any small script
Have a p570 LPAR capped/smt set to 4 physical processors. And currently have virtual processors set to 6 which gives 12 logical processors at AIX. This is for an Oracle9i database server running 4 instances.
What should virtual processors be set to? at least initially?
And how to determine when... (3 Replies)
Hi,
I have two questions here.
I need to find out the number of physical processors the HP-UX operating system is running in. Here i am referring to the physical processors in a system and not the number of cores.
I can get the number of cores using the command 'ioscan -fnkC processor'.... (7 Replies)
Hi all,
I am new to Linux kernel/user space programming having been an assembly programmer in my previous life. I am now using 2.6.x kernel on an embedded CPU that has a few dedicated hardware blocks (including more CPU running just C-code, i.e., no operating system).
There is a single DRAM... (1 Reply)
Hi,
I am on an Solaris machine "SunOS 5.10 Generic_139556-08 i86pc i386 i86pc"..how do i check if I am on an physical or an virtaul server.
Thanks. (6 Replies)
First of all I have performed a Google search and internal search and found several descriptions but nothing I can wrap my head around and feel 100% confident about.
I feel really silly for asking this as I manage a P6 570 with 12 lpars but I have difficulity with Virtual Processors.
I can... (3 Replies)

Hi All,
How can I know whether the server I am connecting to is a virtual or physical one? The server might be having any Unix OS (Linux/Solaris/HP-UX etc.).
Is there any system files / commands which can show these concrete information?
Thanks in advance for the replies.

hi,
I am using command psrinfo -p to check the number of physical processors present on any soalris machine.I want to check the number of virtual processors assigned for particular solaris machine.
which command/set of command need to be used which can grep or show the total virtual processors... (8 Replies)

isainfo
isainfo(1) User Commands isainfo(1)NAME
isainfo - describe instruction set architectures
SYNOPSIS
isainfo [ [-v] [-b | -n | -k] | [-x]]
DESCRIPTION
The isainfo utility is used to identify various attributes of the instruction set architectures supported on the currently running system.
Among the questions it can answer are whether 64-bit applications are supported, or whether the running kernel uses 32-bit or 64-bit device
drivers.
When invoked with no options, isainfo prints the names of the native instruction sets for applications supported by the current version of
the operating system. These are a subset of the list returned by isalist(1). The subset corresponds to the basic applications environments
supported by the currently running system.
OPTIONS
The following options are supported:
-b Prints the number of bits in the address space of the native instruction set.
-k Prints the name of the instruction set(s) used by the operating system kernel components such as device drivers and STREAMS modules.
-n Prints the name of the native instruction set used by portable applications supported by the current version of the operating system.
-v When used with the -b, -k or -n options, prints more detailed information.
-x Prints instruction extensions to the native ABI which are supported by the platform.
EXAMPLES
Example 1 Invoking isainfo on a 32-bit x86 Platform
The following example invokes isainfo on a 32-bit x86 platform:
example% isainfo -v
32-bit i386 applications
example% isainfo -k
i386
Example 2 Invoking isainfo on a System Running the 64-bit Operating System on a 64-bit SPARC Processor
The following example invokes isainfo on a system running the 64-bit operating system on a 64-bit SPARC processor:
example% isainfo
sparcv9 sparc
example% isainfo -n
sparcv9
example% isainfo -v
64-bit sparcv9 applications
32-bit sparc applications
example% isainfo -vk
64-bit sparcv9 kernel modules
Example 3 Invoking isainfo -x on an AMD Opteron CPU
The following example invokes isainfo with the -x option on an AMD Opteron CPU:
example% isainfo -x
i386: fpu tsc cx8 sep cmov mmx ammx a3dnow a3dnowx fxsr sse sse2 pause
EXIT STATUS
Non-zero Options are not specified correctly, or the command is unable to recognize attributes of the system on which it is running. An
error message is printed to stderr.
