From 09c3a97a4c9aace6e2c52823679b31323cab42f6 Mon Sep 17 00:00:00 2001 From: Tushar Krishna Date: Mon, 21 Mar 2011 22:51:58 -0400 Subject: This patch adds the network tester for simple and garnet networks. The tester code is in testers/networktest. The tester can be invoked by configs/example/ruby_network_test.py. A dummy coherence protocol called Network_test is also addded for network-only simulations and testing. The protocol takes in messages from the tester and just pushes them into the network in the appropriate vnet, without storing any state. --- .../ruby/network/garnet/fixed-pipeline/GarnetNetwork_d.cc | 14 +++++++------- .../network/garnet/fixed-pipeline/NetworkInterface_d.cc | 9 +++------ 2 files changed, 10 insertions(+), 13 deletions(-) (limited to 'src/mem/ruby/network/garnet/fixed-pipeline') diff --git a/src/mem/ruby/network/garnet/fixed-pipeline/GarnetNetwork_d.cc b/src/mem/ruby/network/garnet/fixed-pipeline/GarnetNetwork_d.cc index dbfabc8f1..f0b8ccce7 100644 --- a/src/mem/ruby/network/garnet/fixed-pipeline/GarnetNetwork_d.cc +++ b/src/mem/ruby/network/garnet/fixed-pipeline/GarnetNetwork_d.cc @@ -307,15 +307,15 @@ GarnetNetwork_d::printStats(ostream& out) const } out << "-------------" << endl; - // out << "Total flits injected = " << m_flits_injected << endl; - // out << "Total flits received = " << m_flits_received << endl; + out << "Total flits injected = " << m_flits_injected << endl; + out << "Total flits received = " << m_flits_received << endl; out << "Average network latency = " << ((double) m_network_latency/ (double) m_flits_received)<< endl; - // out << "Average queueing latency = " - // << ((double) m_queueing_latency/ (double) m_flits_received)<< endl; - // out << "Average latency = " - // << ((double) (m_queueing_latency + m_network_latency) / - // (double) m_flits_received)<< endl; + out << "Average queueing (at source NI) latency = " + << ((double) m_queueing_latency/ (double) m_flits_received)<< endl; + out << "Average latency = " + << ((double) (m_queueing_latency + m_network_latency) / + (double) m_flits_received)<< endl; out << "-------------" << endl; double m_total_link_power = 0.0; diff --git a/src/mem/ruby/network/garnet/fixed-pipeline/NetworkInterface_d.cc b/src/mem/ruby/network/garnet/fixed-pipeline/NetworkInterface_d.cc index 8299a294f..14105a38c 100644 --- a/src/mem/ruby/network/garnet/fixed-pipeline/NetworkInterface_d.cc +++ b/src/mem/ruby/network/garnet/fixed-pipeline/NetworkInterface_d.cc @@ -241,12 +241,9 @@ NetworkInterface_d::wakeup() bool free_signal = false; if (t_flit->get_type() == TAIL_ || t_flit->get_type() == HEAD_TAIL_) { free_signal = true; - // When we are doing network only testing, the messages do not - // have to be buffered into the protocol buffers - if (!m_net_ptr->isNetworkTesting()) { - outNode_ptr[t_flit->get_vnet()]-> - enqueue(t_flit->get_msg_ptr(), 1); - } + + outNode_ptr[t_flit->get_vnet()]->enqueue( + t_flit->get_msg_ptr(), 1); } // Simply send a credit back since we are not buffering // this flit in the NI -- cgit v1.2.3
