Perangkat Lunak

Debian GNU/Linux 5.0 (lenny)
Kerrighed SVN Trunk¹⁾
Additional and development packages²⁾: build-essential³⁾, bzip2, automake⁴⁾, libtool⁵⁾, pkg-config⁶⁾, rsync, lsb-release⁷⁾, xmlto⁸⁾, libncurses5-dev⁹⁾, kernel-package¹⁰⁾ –if you want to package the kernel into debian package

Jika sering mendapatkan pesan kesalahan Permission denied, tambahkan sudo
di depan perintah tersebut atau gunakan hak root

Compilation and Installation Steps

sha256sum -c krg-20090203.tar.bz2.sha256
Change directory to /usr/src/
```
cd /usr/src/
```
tar jxf /home/stwn/krg-20090203.tar.bz2
cd krg-20090203
./autogen.sh

Configure source with your system, don't –enable-tests, it's broken

Save default configuration for kerrighed
```
make defconfig
```
Configure kernel if you want to add some network drivers you use in cluster
```
# cd kernel
# make menuconfig
```
I added support for many network cards available in 2.6.20 as module and configure built-in kernel for network card I use in cluster like sis900[*] e1000e[*] and [M] for others type which aren't selected as default. [ Device Drivers - Network device support - Ethernet (10 or 100Mbit|Ethernet 1000Mbit ]

Compile the kernel

cd ..
make kernel

or

sudo vim /etc/kernel-pkg.conf
make-kpkg --initrd --revision=2.6.20-svn-022009-1 kernel_image kernel_headers

Install kernel

make kernel-install

or

cd ..
sudo dpkg -i linux-image-2.6.20-krg_2.6.20-svn-022009-1_i386.deb

Compile kerrighed modules, tool and libkerrighed
```
make
```
NOTES: kerrighed modules are compiled with version 2.6.20-krg, if you want to append-version with make-kpkg, just change the version in kerrighed-2.2.1.
Install kerrighed tool and libkerrighed
```
make install
```

Remove default kernel in Debian, if you want to :)

dpkg -P linux-image-2.6.26-1-686 linux-image-2.6-686

Reboot

Head Node

Kerrighed

Configure network card, if you haven't configured it yet

vim /etc/network/interfaces

auto lo eth1
iface lo inet loopback

iface eth1 inet static

Set boot parameter in /boot/grub/menu.lst, add “session_id=1 node_id=1”

initrd          /boot/initrd.img-2.6.20-krg

Set /etc/hosts. NFS and MPI will resolve hostname to IP, so make sure it sets correctly.
Reboot

TFTP & PXE Server

Install atftpd and syslinux¹¹⁾
```
apt-get install atftpd syslinux
```
mkdir /srv/tftpboot
cp /usr/lib/syslinux/pxelinux.0 /srv/tftpboot/
cd /srv/tftpboot/
mkdir pxelinux.cfg

vim pxelinux.cfg/default

Remove initrd, if you found out a hang state with error message “Wait for root filesystem”. It's in initramfs, I don't know it's buggy or something.

Apa yang dilakukan di sistem server network booting, lakukan juga pada NFSROOT

Compute Node

Boot with PXE or gPXE, suite to your network card. Download compiled gPXE/etherboot from rom-o-matic.net

Testing

apt-get install cpuburn
burnMMX & # 3-4 times :-)

Blender

apt-get install blender
chroot /NFSROOT/kerrighed
apt-get install blender

MPI

Setting up ssh in head-node and system inside NFSROOT

ssh-keygen
cp .ssh/id_rsa.pub /NFSROOT/kerrighed/home/stwn/.ssh/authorized_keys
chroot /NFSROOT/kerrighed/
su stwn
ssh-keygen
<Ctrl-D>
cp /NFSROOT/kerrighed/home/stwn/.ssh/id_rsa.pub /home/stwn/.ssh/authorized_keys

Make sure /etc/hosts is set with hosts and their IPs, there is a resolving process during mpirun
Set variable P4_RSHCOMMAND to ssh
```
P4_RSHCOMMAND=ssh
```
Create a machine list file
```
krg-node0
krg-node1
```
apt-get install mpich-bin libmpich1.0-dev
mpicc mm-mpi.c -o mm-mpi
Run MPI program with mpirun
```
mpirun -np 4 ./Pi
```

cp id_rsa.pub authorized_keys
sudo cp /home/stwn/.ssh/authorized_keys /NFSROOT/home/stwn/.ssh/id_rsa.pub
sudo cp /home/stwn/.ssh/id_rsa.pub /NFSROOT/kerrighed/home/stwn/.ssh/authorized_keys

vim mm-mpi.c
vim machinefile
mpicc mm-mpi.c -o mm-mpi
krgcapset -d +CAN_MIGRATE
export P4_RSHCOMMAND=ssh
mpirun -machinefile machinefile -np 16 ./mm-mpi

vim cpi.c

gcc cpi.c
vim Pi.c 
mpicc Pi.c
./a.out 
mpirun -np 24 ./a.out 
mpirun -np 2 ./a.out 
mpirun -np 4 ./a.out

OpenMP

OpenMP support in Kerrighed is unknown, people from NCHC said there is no support for OpenMP in Kerrighed
based-on reply email from Renauld Lottiaux

apt-get install gcc-4.2
vim mm-openmp.c

Compile it

gcc-4.2 -fopenmp mm-openmp.c -o mm-openmp

export OMP_NUM_THREADS=10
Run mm-openmp
```
time ./mm-openmp
```

Loop

This simple loop program will test the process migration feature of Kerrighed with kernel 2.6.20.

First, login to your console
Set Kerrighed capability to CAN_MIGRATE
```
krgcapset -d +CAN_MIGRATE
```
Create a simple program containing infinite loop and compile it
Copy the exact program to the other nodes with the same absolute directory location
Run loop program in one node
```
loop &
loop &
loop &
loop &
```

Problems

I run 4 blender process in node and has set capability set to CAN_MIGRATE, but none of this 4 process migrated. They like hung up on something, and some messages appeared:
```
Null mapping count, non null mapping address : [mem-addr]
```
Blender uses relatively big data and process, and is this the reason why blender process could not be migrated to another nodes? strongly connected?
A program called cpuburn that does FPU calculations and check its result did well, but it still give us some messages
```
Null mapping count, non null mapping address : [mem-addr]
```
The message is on shm_memory_linker.c, this deal with kerrighed's container?
Programs that run on head node could not migrated to another node
