hi,
we all know /proc is about the information of active process,
I have just read an artical which said you can use /proc/cpuinfo,
/proc/net./proc/meminfo etc. to know about some hardware
information .But I want to know how to use with command line? (1 Reply)
I did a search on this, but didn't find exactly the answer I'm looking for. What exactly is the proc directory for? Showing processes spawned by users? I ask because I have some very large files in that directory by multiple users and its affecting my disk usage. Can you limit how many... (2 Replies)
Hi,

hi all !
Please help me
When I select data from oracle with proc * C prog.
I count the number of rows
For example the total rows is 1000000
but the number of result return is a limit number 5000 for ex
So How can I know this limit (5 Replies)
Perhaps this is a very dummy question but sorry I don't know other place to do it. We just buy a new cluster of Xeon machines but there is something I don't understand and perhaps someone can help me.
The more /proc/cpuinfo produces the following output (just part of it).
processor : 0... (1 Reply)
Hi,
I am trying to calculate the CPU Usage by getting the difference between the idle time reported by /proc/stat at 2 different intervals. Now the 4th entry in the first line of /proc/stat will give me the 'idle time'. But I also came across /proc/uptime that gives me 2 entries : 1st one as the... (0 Replies)
So, I'm looking over /proc/cpuinfo and have a question... I've read that "siblings" refers to hyperthreading, but that seems odd considering the contents of cpuinfo. Here's a part:
model name : Intel(R) Xeon(R) CPU E5410 @ 2.33GHz
physical id : 0
siblings : 4

If you are adding the kernel module without any module parameter passing, it should print out following information to info1 file so that user can make read access to info1 file (via, for example, cat /proc/info1):
• Processor type
• Kernel version
• Total number of the processes currently... (1 Reply)
Hi,
I wanted to understand what exactly /proc/cpuinfo shows?
We have a machine with following specification...
(2x) Intel Xeon 6-core processors
So, ideally it shouls have 12processors, but the output on /proc/cpuinfo shows 24 processors.
Can someone please explain how this is... (3 Replies)

pset_create
pset_create(2) System Calls pset_create(2)NAME
pset_create, pset_destroy, pset_assign - manage sets of processors
SYNOPSIS
#include <sys/pset.h>
int pset_create(psetid_t *newpset);
int pset_destroy(psetid_t pset);
int pset_assign(psetid_t pset, processorid_t cpu, psetid_t *opset);
DESCRIPTION
These functions control the creation and management of sets of processors. Processor sets allow a subset of the system's processors to be
set aside for exclusive use by specified LWPs and processes. The binding of LWPs and processes to processor sets is controlled by
pset_bind(2).
The pset_create() function creates an empty processor set that contains no processors. On successful return, newpset will contain the ID
of the new processor set.
The pset_destroy() function destroys the processor set pset, releasing its constituent processors and processes. If pset is PS_MYID, the
processor set to which the caller is bound is destroyed.
The pset_assign() function assigns the processor cpu to the processor set pset. A processor that has been assigned to a processor set will
run only LWPs and processes that have been explicitly bound to that processor set, unless another LWP requires a resource that is only
available on that processor.
On successful return, if opset is non-null, opset will contain the processor set ID of the former processor set of the processor.
If pset is PS_NONE, pset_assign() releases processor cpu from its current processor set.
If pset is PS_QUERY, pset_assign() makes no change to processor sets, but returns the current processor set ID of processor cpu in opset.
If pset is PS_MYID, processor cpu is assigned to the processor set to which the caller belongs. If the caller does not belong to a proces-
sor set, processor cpu is released from its current processor set.
These functions are restricted to privileged processes, except for pset_assign() when pset is PS_QUERY.
RETURN VALUES
Upon successful completion, these functions return 0. Otherwise, -1 is returned and errno is set to indicate the error.
ERRORS
These functions will fail if:
EBUSY The processor could not be moved to the specified processor set.
EFAULT The location pointed to by newpset was not writable by the user, or the location pointed to by opset was not NULL and not
writable by the user.
EINVAL The specified processor does not exist, the specified processor is not on-line, or an invalid processor set was specified.
ENOMEM There was insufficient space for pset_create to create a new processor set.
ENOTSUP The pools facility is active. See pooladm(1M) and pool_set_status(3POOL) for information about enabling and disabling the
pools facility.
EPERM The {PRIV_SYS_RES_CONFIG} privilege is not asserted in the effectvie set of the calling process.

The processor set type of PS_SYSTEM is no longer supported.
Processors with LWPs bound to them using processor_bind(2) cannot be assigned to a new processor set. If this is attempted, pset_assign()
will fail and set errno to EBUSY.
