Re: [Gems-users] : How to set up the network file for MESI_SCMP_tiledL2bank_directory protocol

[Calvin <calvincv@xxxxxxxxx>]

Mike,

By the way, I was a little confused by the name of
MESI_SCMP_tiledL2bank_directory. I thought it implements the MESI
protocol (based on the name). But the generated HTML files says it's
"MSI Directory L1 Cache" and "MOSI Directory L2 Cache"?
