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

[Mike Marty <mikem@xxxxxxxxxxx>]

Ok, you've discovered a couple bugs.

1)  Set L2_RESPONSE_LATENCY to be the same as L2_REQUEST_LATENCY

2)  In the MESI_SCMP_tiledL2bank_directory-L2cache.sm file, change this
line (#815 i think):

      enqueue(L1Network_out, L1Msg) {

To:

      enqueue(L1network_out, L1Msg, latency="L2_RESPONSE_LATENCY") {


Let me know if that helps
