We are upgrading our server to a 4 cpu-Xeon - Dell machine and
I need to make a decision about which cpu's to get. The Xeon's
now come with L3 cache (4mb, 8mb, or 16mb). The cost difference
between four 2.6Ghz-4mb L3 and four 3.2Ghz-16mb L3 is 3,0000$. I've seen
seen discussions regarding other issues, but not this one. Many
application will run faster with more L3, but many applications won't.
Anyone have an opinion as how much the L3 will affect spm
application processing times (we also run fsl, afni, analyze,
......).
Thanks for any input.
