Hello,
I have few old V210/V240, running Solaris-8. I am trying to find, number of physical CPUs, number of cores and number of virtual processors. psrinfo is giving me confusing status.
It looks like, there are 2 physical CPUs, but psrinfo -p shows me just 1
Please suggest
Thanks in advance
I have an E15K running at 60% CPU usage on 16 CPUs.
I need to get rid of 6 CPUs, which is 38%.
Does that mean my CPU usage will go up to 98%?
I suspect the relationship between CPU numbers and usage is a bit more complicated. Can anyone give me any guidance on this please?
TIA (0 Replies)
Hello all :)
I need some help; I'm running the sp_spaceused command on various tables and saving the output to a file. So, I have an input file that has 3 rows - each row has 7 columns. I would like to 1) sort the file on the 4th column, 2) take the 4th column in the first row and add 25% to... (2 Replies)
Hi All
I like to know how can we calculate the number of rows and the average of the values present in the file. I will not know what will be the rowcount, which will be dynamic in nature of the file.
eg.

Hey all
Im looking to reduce the number of cpus available on a certain node in our cluster available for jobs using SGE.
i.e. we have one node that has 24 cpus available for jobs on SGE, i would like to reduce that to 16. Thanks (1 Reply)

psrinfo(1M) System Administration Commands psrinfo(1M)NAME
psrinfo - displays information about processors
SYNOPSIS
psrinfo [-p] [-v] [processor_id...]
psrinfo [-p] -s processor_id
DESCRIPTION
psrinfo displays information about processors. Each physical processor may support multiple virtual processors. Each virtual processor is
an entity with its own interrupt ID, capable of executing independent threads.
Without the processor_id operand, psrinfo displays one line for each configured processor, displaying whether it is on-line, non-interrupt-
ible (designated by no-intr), spare, off-line, faulted or powered off, and when that status last changed. Use the processor_id operand to
display information about a specific processor. See OPERANDS.
OPTIONS
The following options are supported:
-s processor_id Silent mode. Displays 1 if the specified processor is fully on-line. Displays 0 if the specified processor is non-inter-
ruptible, spare, off-line, faulted or powered off.
Use silent mode when using psrinfo in shell scripts.
-p Display the number of physical processors in a system.
When combined with the -v option, reports additional information about each physical processor.
-v Verbose mode. Displays additional information about the specified processors, including: processor type, floating point
unit type and clock speed. If any of this information cannot be determined, psrinfo displays unknown.
When combined with the -p option, reports additional information about each physical processor.
OPERANDS
The following operands are supported:
processor_id The processor ID of the processor about which information is to be displayed.
Specify processor_id as an individual processor number (for example, 3), multiple processor numbers separated by spaces
(for example, 1 2 3), or a range of processor numbers (for example, 1-4). It is also possible to combine ranges and (indi-
vidual or multiple) processor_ids (for example, 1-3 5 7-8 9).
EXAMPLES
Example 1: Displaying Information About All Configured Processors in Verbose Mode
The following example displays information about all configured processors in verbose mode.
psrinfo -v
Example 2: Determining If a Processor is On-line
The following example uses psrinfo in a shell script to determine if a processor is on-line.
if [ "`psrinfo -s 3 2> /dev/null`" -eq 1 ]
then
echo "processor 3 is up"
fi
Example 3: Displaying Information About the Physical Processors in the System
With no additional arguments, the -p option displays a single integer: the number of physical processors in the system:
> psrinfo -p
8
psrinfo also accepts command line arguments (processor IDs):
> psrinfo -p 0 512 # IDs 0 and 512 exist on the
1 # same physical processor
> psrinfo -p 0 1 # IDs 0 and 1 exist on different
2 # physical processors
In this example, virtual processors 0 and 512 exist on the same physical processor. Virtual processors 0 and 1 do not. This is specific to
this example and is and not a general rule.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
