[BioBrew Users] Cross Kickstarting w/ BioBrew on Rocks 4.1

[John J. Rux, Ph.D.]

Glen (and others),
         I am upgrading our existing Rocks 4.1 cluster with i386 frontend 
and compute nodes with some new equipment.  I have a new  x86_64 frontend 
and a mixture of new x86_64 compute nodes and the previous i386 compute 
nodes.  I have installed the x86_64 versions of the Rocks and BioBrew rolls 
onto the new x86_64 frontend.  As before, the BioBrew rpm's didn't get 
installed so I used the rpm approach suggest by Glen (see below).
         Next, I followed the Rocks user guide instructions for Cross 
Kickstarting, but again the distribution that gets created doesnt 
incorporate the BioBrew files correctly.  How do I get the i386 BioBrew 
rpms installed on the compute nodes?  Can I just copy the rpm's to the 
compute nodes and use the same rpm install method that I used on the x86_64 
frontend or will i386 version files collide with the x86_64 files on the 
frontend?  How do you ensure that the compute nodes access the correct 
binary file for applications that are shared (e.g. blast)?
         Finally, if someone has BioBrew rolls for i386 and x86_64 that 
work correctly could they please upload the ISO files.
         Thanks for the help.

setting up a cluster with an EM64T frontend, several EM64T compute nodes, 
and some x86 compute nodes.
