From 40bcbf42539fec83628f2ae2627238adff27f62c Mon Sep 17 00:00:00 2001 From: Brad Beckmann Date: Thu, 28 Apr 2011 17:18:14 -0700 Subject: network: convert links & switches to first class C++ SimObjects This patch converts links and switches from second class simobjects that were virtually ignored by the networks (both simple and Garnet) to first class simobjects that directly correspond to c++ ojbects manipulated by the topology and network classes. This is especially true for Garnet, where the links and switches directly correspond to specific C++ objects. By making this change, many aspects of the Topology class were simplified. --HG-- rename : src/mem/ruby/network/Network.cc => src/mem/ruby/network/BasicLink.cc rename : src/mem/ruby/network/Network.hh => src/mem/ruby/network/BasicLink.hh rename : src/mem/ruby/network/Network.cc => src/mem/ruby/network/garnet/fixed-pipeline/GarnetLink_d.cc rename : src/mem/ruby/network/Network.hh => src/mem/ruby/network/garnet/fixed-pipeline/GarnetLink_d.hh rename : src/mem/ruby/network/garnet/fixed-pipeline/GarnetNetwork_d.py => src/mem/ruby/network/garnet/fixed-pipeline/GarnetLink_d.py rename : src/mem/ruby/network/garnet/fixed-pipeline/GarnetNetwork_d.py => src/mem/ruby/network/garnet/fixed-pipeline/GarnetRouter_d.py rename : src/mem/ruby/network/Network.cc => src/mem/ruby/network/garnet/flexible-pipeline/GarnetLink.cc rename : src/mem/ruby/network/Network.hh => src/mem/ruby/network/garnet/flexible-pipeline/GarnetLink.hh rename : src/mem/ruby/network/garnet/fixed-pipeline/GarnetNetwork_d.py => src/mem/ruby/network/garnet/flexible-pipeline/GarnetLink.py rename : src/mem/ruby/network/garnet/fixed-pipeline/GarnetNetwork_d.py => src/mem/ruby/network/garnet/flexible-pipeline/GarnetRouter.py --- src/mem/ruby/network/simple/SimpleNetwork.cc | 30 ++++++++++++++++++---------- 1 file changed, 19 insertions(+), 11 deletions(-) (limited to 'src/mem/ruby/network/simple/SimpleNetwork.cc') diff --git a/src/mem/ruby/network/simple/SimpleNetwork.cc b/src/mem/ruby/network/simple/SimpleNetwork.cc index 879ae2f7f..15107b17f 100644 --- a/src/mem/ruby/network/simple/SimpleNetwork.cc +++ b/src/mem/ruby/network/simple/SimpleNetwork.cc @@ -35,6 +35,7 @@ #include "mem/protocol/TopologyType.hh" #include "mem/ruby/buffers/MessageBuffer.hh" #include "mem/ruby/common/NetDest.hh" +#include "mem/ruby/network/BasicLink.hh" #include "mem/ruby/network/simple/SimpleNetwork.hh" #include "mem/ruby/network/simple/Switch.hh" #include "mem/ruby/network/simple/Throttle.hh" @@ -133,9 +134,10 @@ SimpleNetwork::~SimpleNetwork() // From a switch to an endpoint node void -SimpleNetwork::makeOutLink(SwitchID src, NodeID dest, - const NetDest& routing_table_entry, int link_latency, int link_weight, - int bw_multiplier, bool isReconfiguration) +SimpleNetwork::makeOutLink(SwitchID src, NodeID dest, BasicLink* link, + LinkDirection direction, + const NetDest& routing_table_entry, + bool isReconfiguration) { assert(dest < m_nodes); assert(src < m_switch_ptr_vector.size()); @@ -147,15 +149,19 @@ SimpleNetwork::makeOutLink(SwitchID src, NodeID dest, } m_switch_ptr_vector[src]->addOutPort(m_fromNetQueues[dest], - routing_table_entry, link_latency, bw_multiplier); + routing_table_entry, + link->m_latency, + link->m_bw_multiplier); + m_endpoint_switches[dest] = m_switch_ptr_vector[src]; } // From an endpoint node to a switch void -SimpleNetwork::makeInLink(NodeID src, SwitchID dest, - const NetDest& routing_table_entry, int link_latency, int bw_multiplier, - bool isReconfiguration) +SimpleNetwork::makeInLink(NodeID src, SwitchID dest, BasicLink* link, + LinkDirection direction, + const NetDest& routing_table_entry, + bool isReconfiguration) { assert(src < m_nodes); if (isReconfiguration) { @@ -168,9 +174,10 @@ SimpleNetwork::makeInLink(NodeID src, SwitchID dest, // From a switch to a switch void -SimpleNetwork::makeInternalLink(SwitchID src, SwitchID dest, - const NetDest& routing_table_entry, int link_latency, int link_weight, - int bw_multiplier, bool isReconfiguration) +SimpleNetwork::makeInternalLink(SwitchID src, SwitchID dest, BasicLink* link, + LinkDirection direction, + const NetDest& routing_table_entry, + bool isReconfiguration) { if (isReconfiguration) { m_switch_ptr_vector[src]->reconfigureOutPort(routing_table_entry); @@ -193,7 +200,8 @@ SimpleNetwork::makeInternalLink(SwitchID src, SwitchID dest, // Connect it to the two switches m_switch_ptr_vector[dest]->addInPort(queues); m_switch_ptr_vector[src]->addOutPort(queues, routing_table_entry, - link_latency, bw_multiplier); + link->m_latency, + link->m_bw_multiplier); } void -- cgit v1.2.3
