3.4 Distribution Specific Build Details

The following are known issues with building on common distributions. Please refer to the

Ammasso support website (

www.ammasso.com/support) for an up to date list of issues.

The list of packages provided below will ensure that the system will be able to take

advantage of all the Ammasso 1100 features – such as being able to support 32-bit MPI

applications on 64-bit platforms.

3.4.1 RedHat

The following section lists RedHat distribution specific details. While the exact keystrokes

may vary slightly from release to release, the following are offered as guidelines for these

distributions.

3.4.1.1 RedHat Package Selection

On 32-bit platforms, ensure that both Development Tools and Kernel

Development packages are selected from redhat-config-packages menu. These

allow you to build the Ammasso driver software.

On 64-bit platforms, select the following packages in the System group under redhat-

config-packages menu: Development Tools, Kernel Development,

Legacy Software Development, and Compatibility Arch Support. In

addition, under the Development Group menu select the following: Compatibility

Arch Development Support and Legacy Software Development. Installing

these packages will allow both 32-bit and 64-bit MPI applications to run on the 64-bit

installed system.

3.4.1.2 RedHat Kernel Source Tree Preparation

First ensure the system has a clean source tree by doing a make mrproper:

# cd /usr/src/linux

# make mrproper

Next, edit the Makefile so that the version value matches the running kernel. By default,

the variable EXTRAVERSION includes the string custom. Change this variable to match

the running kernel. The running kernel version can be found using uname –r. For

example, modify -15.ELcustom to -15.ELsmp.

After that, initialize the .config file for your system. This can be accomplished by

copying the config file from /boot and doing a make oldconfig.

# cd /usr/src/linux

# cp /boot/config-`uname –-kernel-release` /usr/src/linux/.config

# make oldconfig

Finally, execute the kernel dependent target to update configuration files and rebuild the

source dependencies.
