Hello,
I have a Supermicro server with a P4SCI mother board running Debian Sarge 3.1. This is the "dmidecode" output related to RAM info:
RAM speed information is incomplete.. "Current Speed: Unknown", is there anyway/soft to get the speed of installed RAM modules? thanks!!

Hi,
I am looking to use a semaphore for the first time in one of my scripts. I am just wondering if there are any simple examples or tutorials around?
I am a beginner so the simpler the better :)
Thanks

If I create a semaphore and then I fork a number of child processes then all the child process use that same semaphore.
Since the process address spaces are different rfom each other then how all the child process are able to access the same semaphore?

I was asked to add this piece of code to a c program which I will execute through the shell:
for(long i = 0; i < NITER; i++)
{ sem_wait( &sema);
count++;
sem_post( &sema); }
I didn't get it, which is the critical section ? if it's "count++" how would a thread wake up in order to enter it... (1 Reply)

lscpu
LSCPU(1) User Commands LSCPU(1)NAME
lscpu - display information on CPU architecture
SYNOPSIS
lscpu [-hpx] [-s directory]
DESCRIPTION
lscpu gathers CPU architecture information like number of CPUs, threads, cores, sockets, NUMA nodes, information about CPU caches, CPU fam-
ily, model, bogoMIPS, byte order and stepping from sysfs and /proc/cpuinfo, and prints it in a human-readable format. It supports both
online and offline CPUs. It can also print out in a parsable format, including how different caches are shared by different CPUs, which
can be fed to other programs.
OPTIONS -h, --help
Print a help message.
-p, --parse [=list]
Print out in parsable instead of human-readable format.
If the list argument is not given then the default backwardly compatible output is printed. The backwardly compatible format uses
two commas to separate CPU cache columns. If no CPU caches are identified, then the cache columns are not printed at all.
The list argument is comma delimited list of the columns. Currently supported are CPU, Core, Node, Socket, Book and Cache columns.
If the list argument is given then always all requested columns are printed in the defined order. The Cache columns are separated by
':'.
Note that the optional list argument cannot be separated from the option by a space, the correct form is for example '-p=cpu,node'
or '--parse=cpu,node'.
-s, --sysroot directory
Use the specified directory as system root. This allows you to inspect a snapshot from a different system.
-x, --hex
Use hexadecimal masks for CPU sets (e.g. 0x3). The default is to print the sets in list format (e.g. 0,1).
BUGS
The basic overview about CPU family, model, etc. is always based on the first CPU only.
Sometimes in Xen Dom0 the kernel reports wrong data.
