IBM Blue Gene/L series

FTB is currently supported on the BG/L machines using the open-source ZeptoOS operating system and the ZOID I/O function forwarding mechanism. This necessitates that both ZeptoOS and ZOID be functional on your BG/L machine before FTB can be used. For further reading on ZeptoOS and ZOID : http://www.mcs.anl.gov/research/projects/zeptoos/

In order to use FTB on the ANL machines, the following steps are recommended:

Step 1: Get an account created on the BG/L machine and profile directory created under the /bgl NFS system (For ex: /bgl/argonne-utils/profiles/user-xyz). The latter is the conventional directory for storing images intended for the I/O nodes.

Step 2: You need to now build ZeptoOS (consists of Linux- replaced kernel, ramdisk, build tools for I/O nodes and optional support for PVFS2, KTAU and ZOID. ZOID is a replacement for function forwarding deamon COID. The source code and the documentation for installing the software can be found at:http://www.mcs.anl.gov/research/projects/zeptoos/

We recommend that you follow the guidelines mentioned in the supported ZeptoOS release documentation to configure ZeptoOS and ZOID.

Step 3: Test your ZeptoOS and ZOID installation.
