Phoronix IRC Log: 2010-09-27
cohonen: hey guys
cohonen: i see the intel drivers still suck
EcEnTiAl: meep meep
doghawk: I'm looking for a simple benchmarking tool to run on Ubuntu Server (from the command line)
burra: what do you want do bechmark, I have used geekbensh for linux. That is a easy one
burra: then there is the phoronix test suite
burra: but that one is more complex
doghawk: I want to benchmark my CPU and memory
doghawk: I just need to be able to run it from the command line
burra: then geekbench is nice
burra: the result browser can also give you an hint
burra: the 64bit version is not free
burra: in my test by running the 64bit version of geekbench gives about 20% more points
burra: doghawk: what kind of machine are you tesing
burra: I could look what kind of points you should need to get
doghawk: Dell PowerEdge 6650 (Intel Xeon 8x2.5GHz // 32GB of RAM)
doghawk: so… how to I run geekbench from the command line?
doghawk: I've un-tarred it
burra: you have downloaded the .tar.gz
doghawk: and unpacked it
burra: should be two executable inside
doghawk: sorry… I'm a newb… how do I execute those files?
burra: just do ./geekbensh
doghawk: ah… like a script
burra: is this one yours
doghawk: I don't know how that stacks up
burra: hmm if it really is 4 cpus and 8 cores it seems slow
doghawk: I wonder what I need to do to speed it up
burra: you can't use a 64 bit kernel so you don't need to use pae
burra: I think i saw a phoronix test when pae seems to slow down performance
doghawk: so I should be using a different version of linux?
burra: do you have any better specification on the CPU:s in the box
burra: ahh ok did not remeber the outcome of the article correct seems like 32 vs 32 pae kernel don't have any differance
doghawk: I don't know how to tell if my machine is capable of running a 64-bit OS… any ideas?
burra: if the cpu has the 64bit instructions it is possible
burra: can you run cat /proc/cpuinfo | grep "model name"
burra: and uname -a
burra: doghawk: you need to find out what kind of cpu the server has if it is possible to run a 64bit kernel on it
burra: doghawk: that is a place to start
boulabiar: when we will see a video of something using the Gallium-D3d1x ? any news ?
burra: now sleep
orm_: so give it to me straight, should I go gallium3d for my 9800gtx? currently running the proprietary driver.
orm_: I really like the idea of DX10/11 and i think it could really take off if microsoft doesn't go lawsuit crazy over it
orm_: DX10/11 in linux
orm_: that is
orm_: anyone have any opinion on the matter?
orm_: so has anyone tried gallium?
Gnurdux: i don't think there is anything you can try
Gnurdux: at thix point
Gnurdux: i dont think there are usable gallium drivers for nvidia
Gnurdux: and also, the guy says eventually there should be gallium on opengl
Gnurdux: i bet gallium on opengl with proprietary driver would be faster than an open-source gallium driver
orm_: so gallium is more like a companion to a proprietary driver?
Gnurdux: orm_, that's not what it's supposed to be
orm_: so an abstraction over many hardware frameworks?
Gnurdux: gallium is supposed to be a framework which you use to implement a driver
Gnurdux: you implement a gallium driver
Gnurdux: various low level operations
Gnurdux: and implementing these operations lets Gallium produce an OpenGL implementation
orm_: so basically an interface
Gnurdux: and also perhaps OpenCL
Gnurdux: and now apparently direct3d
orm_: i have an image of a C++ pure virtual class in my mind
Gnurdux: the direct3d implementor guy claims that it should be possible to do gallium "backwards"--that is, implement Gallium on OpenGL
Gnurdux: orm_, something along those lines
Gnurdux: you implement some interface
Gnurdux: and Gallium implements lots of stuff that's independent of your implementation of your interface
orm_: so part standard and part code generator
Gnurdux: something like that
Gnurdux: so this guy implemented some sort of direct3d on top of gallium
orm_: now nvidia just needs to drink the koolaid like AMD
mikeplus64: orm_: If you do, #nouveau might be of assistance
