Memory selection

[Dave Lane]

Hi all,

I'm going to be building a AMD MP-based beowulf system this spring and have 
a question or about memory selection for the nodes.

First question is which type of memory to choose: ECC, non-ECC, Registered 
or not. My understanding that registered memory is slower, but allows for 
more capacity (more chips) on a DIMM. This should not be an issue for me, 
since I expect that 512M in each node will be enough.

Second question is if memory errors occur with ECC memory does Linux know 
about and report problems in the logs? (this does occur on Sun Solaris 
systems)?
