Thank you for purchasing GigaAccel 180. This “GigaAccel 180 User’s Manual” describes how to set up, configure, and start up the GigaAccel 180. Included accessories Please confirm that the following items are included in the package. (1) GigaAccel 180 (2) Serial cable...
1 Introduction GigaAccel 180 is an accelerator board based on IBM’s PowerXCell 8i processor. The board has 4GB of DDR2 SDRAM, two 1 Gigabit Ethernet Ports, one x16 PCI Express interface, and it can run Linux. This makes it possible to put the vastly superior floating-point calculation capabilities of PowerXCell 8i on a standard workstation.
Pins are “T2OUT”, “GND”, and “R2IN” from top to bottom in the picture below. Serial port Serial port 2.2 LED descriptions Various LEDs light up on the side of the board with Ethernet ports when GigaAccel 180 is powered on. These LEDs indicate the current status of GigaAccel 180. ⑦ ⑥ ⑤...
3 Connection of GigaAccel 180 This section explains the instructions for connecting GigaAccel 180 onto the host machine. The target host machine must have a x16 PCI Express interface (2 slots), and an AUX 12V 6-pin power connector for PCI Express.
[Note] PCI-express connectors must be handled with care. If the connector is not installed firmly on the slot, GigaAccel180 may not function correctly. (4) Attach the PCI Express AUX 12V 6-pin power connector to GigaAccel 180. AUX12V 6-pin power connector...
Serial Connector(9pin) (6) Connect the Ethernet cable (crossover) to the eth0 port of GigaAccel 180. The port will be used for network booting and NFS mounting. In the following picture, the host machine has DHCP server, TFTP server and NFS server.
(NFS) This section describes how to create the GigaAccel 180 disk image and how to install it to GigaAccel 180. If you are using an OS other than Yellow Dog Enterprise Linux for GigaAccel 180, please skip this section. Also, this instruction assumes that CentOS5.4 is installed on the host machine (x86, 64 bit).
IPADDR=192.168.2.10 NETMASK=255.255.255.0 4.4 Prepare to create boot image and disk image Set the DVD (Yellow Dog Enterprise Linux for GigaAccel 180) into the host machine. Create the installer directory, and mount the DVD drive to the installer directory. # mount /dev/cdrom /mnt -o ro # mkdir -p /nfsroot/ydlinstaller # mount /mnt/iso/ydel-X.X.X-cell.iso /nfsroot/ydlinstaller -o loop...
← IP address of TFTP server next-server 192.168.2.10; ← Boot image file name filename “ppc64.img”; GigaAccel 180 eth0 MAC address is printed on the side of GigaAccel 180 as “1ST MAC:--- ”. Set the DHCP service start up option as follows. # vi /etc/sysconfig/dhcpd...
# minicom Pressing ‘s’ while GigaAccel 180 is running will display the command prompt. * When you configure the host machine, GigaAccel 180 may fail to boot. In this case, press ‘Enter’ key and then the commad prompt is displayed.
“root” Password: Password entered during installation process * To login GigaAccel 180 and to operate, we recommend ssh login described in the following. (2) SSH login Shortly after the host machine has started up the GigaAccel 180 OS will also start up.
Yellow Dog Enterprise Linux user name and password which were notified separately. * To connect to the external network, login to GigaAccel 180, and then, configure “/etc/sysconfig/network-scripts/ifcfg-eth1” file, activate eth1 (by “ifup eth1” command).
Mount the installer DVD and the installer image on the host. # mount /dev/cdrom /mnt -o ro # mount /mnt/iso/ydel-X.X.X-cell.iso /nfsroot/media/DVD -o loop * The following actions will be performed on the GigaAccel 180. Create the mount directory on the host. # mkdir -p /media/DVD Mount the installer DVD on the GigaAccel 180.
5 Installing GigaAccel 180 (CIFS) This section describes how to set up CIFS boot in GigaAccel 180. If you are using nfs boot, there is no need to read this section. The OS is Yellow Dog Enterprise Linux on GigaAccel 180.
“Local Area Connection” will be used for the external network connection (assigned IP address by DHCP server) and “Local Area Connection 2” will be used for communications with GigaAccel 180. In “Local Area Connection 2”, assign the IP address (192.168.2.10) beforehand.
Open “Advance” tab and clear the check box for “Local Area Connection 2”. 5.5 Create boot file and file system Perform creating CIFS boot file and file system for CIFS of GigaAccel 180. Insert “GigaAccel 180 Install DVD” in the host machine.
The second field : //192.168.2.10/CIFS /cifs -o user=root,password=passw0rd [Note] You can enter the second field in less than 63 characters. If an invalid value is entered, GigaAccel 180 can not boot. If GigaAccel 180 can not boot, please refer to the troubleshooting.
5.9 Installation of Terminal Software To confirm the boot status of GigaAccel 180 (to show Serial Console), terminal software is necessary. This section describes the installation of “Tera Term Pro”(http://ttssh2.sourceforge.jp/index.html.en). Go to the download page and download the installer. Run the installer and install with the default settings.
In default configuration you can log in as the “root” user and password is “passw0rd”. (“0” is zero.) * When GigaAccel 180 is running you can log in by ssh. The default IP address of GigaAccel 180 is “192.168.2.11” (this is assigned by the DHCP feature of tftpd32).
Ensure that configuration settings allow GigaAccel 180 to connect to the external network. Also, make sure to have on hand the Yellow Dog Enterprise Linux user name and password which were notified separately.
* The following actions will be performed on the GigaAccel 180. Create the mount directory. # mkdir -p /media/DVD CIFS Mount the Installer DVD and mount install image on the GigaAccel 180. # mount -t cifs //192.168.2.10/DVD /mnt -o ro # mount /mnt/iso/ydel-X.X.X-cell.iso /media/DVD -o loop Create the yum repo file.
7.1 PCI Express driver overview If the OS of the host machine is Linux, installing the PCI Express driver will allow TCP/IP communications with GigaAccel 180 via PCI Express. However, to conduct TCP/IP communications, the driver must be running on both the host machine and GigaAccel 180.
Stop the PCI Express driver with the following command. (On both the host and GigaAccel 180) # service pxcab stop [Note] If the driver was stopped on both the host and GigaAccel 180, then use the following command on both the host and GigaAccel before starting the drivers again. # modprobe axon...
