To use the render node in an InfiniBand-connected background processing network, it must be equipped with an InfiniBand network adapter.
The precompiled QuickSilver (QLogic) InfiniServ 9000 HCA adapter drivers for the Red Hat Enterprise Linux kernel are included in the dist/ib subdirectory of the installation package.
If you are using CentOS, you need to manually compile the InfiniBand driver for your version of the Linux kernel. The source files for the driver are located in the src/infiniband subdirectory of the latest DKU installation package. Refer to your CentOS documentation for information on compiling software. Refer to the README file located inside the driver tar file for instructions on how to install the driver and configure your InfiniBand interface.
