<0> OS cl***?
<1> nope, it is for my own use
<1> I want to be able to demo some funcionality of this system to my boss.
<2> hello
<2> i would need some help
<1> so I really needed to have some tools working
<3> so make them work
<2> void *bs=malloc(10*sizeof(int));(int &)bs=0x989797;printf("%c",(void *)(bs +1) );
<2> how do i really access bs ?
<1> they are working
<4> _Aegis_: how does your scheduler work?
<4> i mean, what does it do?
<1> bis is a pointer to an integer
<2> yes aegis
<2> how do i write/read it ?
<1> well , all it does is check the load average on a list of nodes
<4> the integer or the address of the pointer, drunkmath
<1> and submit a command line to the one with the lowest load average
<4> nifty
<1> it is a little hackish
<1> since I am using a single system image /proc is no available
<2> aegis ?
<1> so I use the c program to generate a shell scriptthat does an uptime on all the nodes and then the c program parses the results
<1> since I can't run rexec I cant do an rhosts
<1> ro a ruptime
<1> or
<1> the syntax is simple "launch <command line>"
<1> it has the option to fork and send the remote task to the background so that you get the command line back right away
<1> the issue I am fignting now is the slowness of ssh
<4> use telnet!
<4> :p
<1> ittakes 4-5 secodns for it to do all the ssh stuff
<1> lol.
<1> I wanna use rexec
<1> but I can't
<1> evil hax0rs will get me
<4> can't you setup rexec on the machines?
<1> I can but it is a security risk
<1> I"m wondering if rpc can be wrapped with ssh ?
<1> then I could use rpc
<4> can't you setup rexec so that it only accepts commands from soemone with a 128-bit key or some thing
<1> umm.. you can wrap rsh with kerberos, but you are back to being slow again
<1> since I have an nfs mount I could just make a file for each node that contians the uptime
<1> that might be faster
<1> a bit more complex tho
<1> I can make the file at each node
<4> how do you calculate uptime?
<1> I use uptime
<1> it gives me th e1 minute average uptime
<1> and I use that to score each node
<1> I guess I'll just have to tighten fdown the firewall and use rsh.
<1> I think tis is good enough to demo
<4> is someone going to but it from you?
<1> all we are after is the concept
<1> umm.. in essence. I'm trying to persuade my empolyer to build a new cluster.
<1> so I tickle their greed with new toys. :)
<5> hmm
<4> lol
<1> not so new, really, but new to them.
<1> and they wil lbenefit from it.
<1> and I get to build anothe rcluster.
<1> the net result is that I secure my employment
<1> ls
<4> .
<4> ..
<4> \warez
<1> hehe
<4> \hackingprogs
<4> \othermiscillegalthings
<1> ever see an installed rootkit ?
<1> weith a "..." directory
<4> heh
<6> How is that a rootkit?
<1> well the one I saw on a box that got hacked was in a directory named "..."
<1> sos you go into a directory and ls and you see: .
<1> ..
<1> ...
<7> yes
<7> ... is to confuse stupid people
<7> common directory name
<1> yah
<4> whenever I deploy a rootkit i put it in a directory called SYSTEMFILESDONOTDELTEMEORTHECOMPUTERWILLDIE and it seems to fool most people
<1> thye just bury it in a directory tree in an inocuous place and nobody is likely to notice it for a long time
<1> lol amazon
<8> I just sell it to Sony and let them distribute it world-wide on CDs.
<1> oh thta has altready been done
<8> if it aint broken dont fix it
<1> yah
<1> and if it is broken, throw it out
<4> if it ain't broken, fix it 'till it is
<1> I guess I have done all I need to do with this computer for now.
<4> okay
<4> send it to me
<1> now I have a way cool new cluster configuration and nothing to run on it.
<4> i'll add it to my beowulf cluster of toasters
<4> run f@h on it
<1> yah we can grid it with your toqaster cluster
<1> AFTER the demo
<1> I'll open it up to use
<4> yay
<4> my prog has no memory leaks
<7> anyone know a new mobo that supports the dual core opterons with a ddr2 memory bus instead of the old ddr1
<4> what are those dual core optys called?
<1> dual copre opteron
<1> core
<4> what socket type is it?
<1> umm. the same as single core
<1> 939 ?
<4> ah
<4> k
<1> lol, I've built two diula cor opteron clusters
<1> they are nice cpus
<1> they are better if you have alots of ram
<7> yea
<7> 4GB enough?
<7> I was thinking of doing a opteron 270 setup
<7> but.. I'm having trouble finding an opteron AM2 motherboard that has a ddr2 memory bus?
<7> :/
<7> no AM2 is not 939
<4> all the ones at newegg use ddr400
<7> it's 940, but renamed to "am2"
<7> yea amazon10x that's old 939 sockets
<7> I can find opteron 1xx series AM2 motherboards, but I need sockets for 2 cpus which is what is killing me
<7> maybe they don't exist yet? :(
<4> amd got mad about everyone saying "why do they have to change the friggin pin count by one" so they gave it a whole new name... but still changed it by one
<1> get a Tyan motherboard
<4> Darken-: you could try posting at ocforums.com. They would probably know
<4> best app ever made by microsoft: Windows Task Manager
<4> they should port it to linux :p
<7> amazon10x I need to know sooner than I will get a response, sadly
<4> they reply quick, often in about 10 minutes
<7> ah nice
<4> won't hurt to try
<4> ensure you put it in the appropriate section for fastest response time. otherwise a mod might delete it
<9> what's an automatic variable
<4> a variable that is automatically allocated by the operating system
<4> and automatically deallocated
<4> ...i think
<9> uhm
<9> where are they stored
<4> in ram
<9> heap/stack?
<10> Stack
<4> --^
<4> what he said
<10> Variables local to a function or non-global scope are automatic
<9> interesting terminology
<10> Don't really bother about the "automatic" part or the "auto" keyword, it's never used since it's ***umed
<10> If you want a variable with a global scope inside a function, you will use the "static" keyword
<9> yeah that's not reentrant though
