[SLUG] IOWait definition
Hello I was wondering if someone could point me in the right direction for some doco? I'm finding it hard to get a definition of what constitutes IOWait. I know that IOwait is CPU time waiting for IO to happen to physical local disks, but I'm unsure about the following scenarios and if they contribute to IOWait: - CPU time waiting for an NFS read/write to occur - CPU time waiting for a network buffer to be read/written to. eg waiting for a full buffer to clear. - Anything else?? Grant PS. How do you set/query the network buffers in Linux? Animal Logic http://www.animallogic.com Please think of the environment before printing this email.

[SLUG] Atom Processor - what distro works?
BODY { font-family:Arial, Helvetica, sans-serif;font-size:12px; }
I'm in Osaka at present. Looking at buying mini-itx mobo that has
atom cpu.
Is there a distro that works with this cpu?
Centos? The EEE PC has an atom cpu doesnt it?
Sorry for asking rather than searching - having laptop problems (or
Hotel LAN problems).
Thanks

Re: [SLUG] Atom Processor - what distro works?
I have an eee pc running on ubuntu eee, it ran fine on xandros, and
there are numerous other distros for it, fedora, mandriva opensuse?.
People have made eee specific kernels such as the ubuntu eee thqt have
the drivers .

Re: [SLUG] Atom Processor - what distro works?
Osaka! I am envious!
I believe, the latest kernels support the Atom processor very well. I
can't see why a distro would need to explicitly support it. Any x86
distro should work, as long as the kernel recognises the atom.
Are they selling the dual core atoms in mini-itx mobos now?
Have fun.

Re: [SLUG] Comp TIA+ / CLP
Last I looked in my VUE page you can book the exams at any VUE testing centre too.

I'm finding it hard to get a definition of what constitutes IOWait. I know that IOwait is CPU time waiting for IO to happen to physical local disks, but I'm unsure about the following scenarios and if they contribute to IOWait: Not quite. IOWait is a *software* state, indicating that a process or thread is blocked waiting for I/O to complete. This is different from CPU time waiting for ... in that it implies the software is making no progress, but *NOT* that your CPU is spending cycles working on it.[1] - CPU time waiting for an NFS read/write to occur Yes, along with more or less any other disk I/O that happens to be run over the network -- as long as it is synchronous, and something is waiting on it. - CPU time waiting for a network buffer to be read/written to. eg waiting for a full buffer to clear. Generally not. I am not certain about blocking on a full buffer condition for sending data, but not for blocking while reading. - Anything else?? Any other synchronous disk I/O, certainly. Probably certain other, related, conditions where the kernel developers feel that the process is blocked on I/O. PS. How do you set/query the network buffers in Linux? Via the socket fcntl / ioctl interface, or via the sysctls in /proc/sys/net, which are documented in the standard Linux kernel sysctl documentation. All that said, you might want to tell us why you are asking, not just what, since I suspect there is a question about why you have so much IOWait time on your system, or poor performance? Regards, Daniel Footnotes: [1] It does, technically, spend a few in terms of submitting and completing the I/O before it wakes up the blocked process, and various I/O devices need babysitting, but the principal is sound. ;) -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
Re: [SLUG] Comp TIA+ / CLP
Some of the issues I am having is how much of any given subject in the LPI in a nutshell I need to know. It starts off with pretty intense Hardware stuff and I was under the impression that it was a different field altogether. I can see why it's relative but I certainly was not expecting it. A course would be my best option, one that doesn't cost me an arm and a leg. I.e one that does not yet exist. That, or someone/people that live close by that want to a form a study group. - I may just post this idea and hope there are those that are keen. Tony.
