Security Notes
ZeptoOS is completely configurable. You may choose to allow user login access, or restrict it. However you configure ZeptoOS, it is important to note that the default configuration from IBM is for the I/O Nodes to NFS mount the /bgl file system with full root privileges. This means that anyone who has root access on the I/O nodes can modify everything on the NFS server. On our machine, we have modified the service node to export /bgl read-only, without observing any adverse effects on the I/O nodes.
Configuring the Build
Configuration
Download the bzipped file on the Bluegene/P login node. Extract the sources by using:
$ tar xjf zeptoos-20.tar.bz2
Change to the BGP top directory using:
$ cd BGP/
Then you can use the configure script to set the system tools path to default using:
$ ./configure
In order to configure the site specific paths using the tool use:
$ ./configure --edit
