Xen GPU Cluster

實作 一: 如何將Dom0上的顯示卡資源分配給DomU

Hardware

Machine	Dell OptiPlex 755
Node	1 node
CPU	Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz
Memory	6GB
Storage	160GB
Video Card	NVIDIA GeForce 9800GT 1GB

Software

OS#1	Ubuntu 8.10 with Kernel: 2.6.28 x86_64 (non-xen-patched kernel)
OS#2	Ubuntu 8.10 with Kernel: 2.6.22-9 x86_64 (Xen-3.3.1+Lustre patched kernel)

Part 1 建構基本環境

步驟一: 連線到遠端主機

# 以下兩種連線方式擇一使用.
rider@cloud:~$ ssh 140.xxx.xxx.xxx
rider@cloud:~$ vncviewer 140.xxx.xxx.xxx

步驟二: 產生一台虛擬機器來使用 CUDA

# 設定你想要怎樣規格的虛擬機器 rider@cloud:~$ sudo vim /etc/xen-tools/xen-tools.conf

dir = /home
install-method = debootstrap
size   = 8Gb      # Disk image size.
memory = 1024Mb    # Memory size
swap   = 128Mb    # Swap size
fs     = ext3     # use the EXT3 filesystem for the disk image.
dist   = hardy    # Default distribution to install. ---> For CUDA Support (Ubuntu 8.0.4)
image  = sparse   # Specify sparse vs. full disk images.
gateway   = 140.XXX.XXX.XXX
netmask   = 255.255.255.0
broadcast = 140.XXX.XXX.XXX
kernel      = /boot/vmlinuz-`uname -r`
initrd      = /boot/initrd.img-`uname -r`
mirror = http://gb.archive.ubuntu.com/ubuntu/
ext3_options   = noatime,nodiratime,errors=remount-ro
ext2_options   = noatime,nodiratime,errors=remount-ro
xfs_options    = defaults
reiser_options = defaults

rider@cloud:~$ sudo xen-create-image --hostname nvidia --ip 140.XXX.XXX.XXX

步驟三: 設定你的虛擬機器

rider@cloud:~$ sudo vim /etc/xen/nvidia.cfg

kernel      = '/boot/vmlinuz-2.6.22.9'
ramdisk     = '/boot/initrd.img-2.6.22.9'
 
memory      = '1024'
vcpus       = '4'
pci         = ['01:00.0']

root        = '/dev/sda2 ro'
disk        = [
                  'file:/home/domains/nvidia/disk.img,sda2,w',
                  'file:/home/domains/nvidia/swap.img,sda1,w',
              ]
name        = 'nvidia'
 
#
#  Networking
#
vif         = [ 'ip=140.xxx.xxx.xxx,mac=00:16:3E:AA:70:5C' ]
 
#
#  Behaviour
#
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'
