Introduction | Top | Installation
Downloading
- Log on one of the frontend nodes of the Blue Gene (a login node or a service node).
- Download the ZeptoOS tarball from the ZeptoOS download page.
- Extract the sources from the package:
tar xjf ZeptoOS-*.tar.bz2
Configuring
Change to the top-level BGP directory:
$ cd BGP/
A configure script is provided to set the pathnames to various system directories. If invoked without any arguments, it will use the defaults, which should be appropriate if ZeptoOS is configured on a system with a supported BG/P driver version. The pathnames can be changed with the help of a user interface by invoking the script as follows:
$ ./configure --edit
Building
Typing make help will bring up the following menu:
[MENU] make - Prepare Zepto kernel and ramdisk images make bgp-ion-ramdisk-cnk - Rebuild ION ramdisk for CNK make bgp-ion-ramdisk-cnl - Rebuild ION ramdisk for CNL make bgp-ion-linux - Simply use recent built or prebuilt ION kernel (no kernel rebuild) make bgp-cn-linux - Rebuild CN ramdisk and merge with recent built or prebuilt CN kernel objs make bgp-ion-linux-build - Rebuild ION kernel make bgp-cn-linux-build - Rebuild CN kernel objs and CN ramdisk, then merge them into CN Kernel make bgp-all-pkg-smart - Build packages from the prebuilt binaries make bgp-all-pkg-rebuild - Rebuild all packages from source
To start using the default built binaries simply type:
$ make
This will copy all the required kernel and ramdisk images to the top level directory.
Examining the Build Directory
If the build was successful, one should be able to see the following new files either rebuilt from sources or copied from their prebuilt locations:
$ ls -l -rwxr-xr-x 1 hnaik users 8629983 2009-01-23 17:16 BGP-CN-zImage-with-initrd.elf -rwxr-xr-x 1 hnaik users 1444183 2009-01-23 17:03 BGP-exp-ION-zImage.elf -rwxr-xr-x 1 hnaik users 10423112 2009-01-23 17:03 BGP-ION-ramdisk-for-CNK.elf -rwxr-xr-x 1 hnaik users 10423988 2009-01-23 17:03 BGP-ION-ramdisk-for-CNL.elf -rw-r--r-- 1 hnaik users 132 2009-01-23 17:03 bgp-ion-ramdisk-passwd.txt -rwxr-xr-x 1 hnaik users 1351583 2009-01-23 17:08 BGP-ION-zImage.elf
