Subject: | [Gems-users] Network Destination generation problem in Garnet NI |
Hi, I use Garnet network tester to run with random traffic. And when I try a large network (128-node), the network interface will generate multiple transaction for the same message. I use MOESI_SMP_directory protocol and I think all the messages should be unicast, like the case of 32-node or 64-node network. But in a 128-node network with CROSSBAR topology, the NI will generate 2 transactions for the same message to the same destination. (dest_nodes.size() == 2) So I got double flit count. Is it a bug in Garnet or I miss something ? Thanks. Jianchen Hu |
