2011-11-04GARNET: adding a fault model for resilient on-chip network research.Tushar Krishna
This patch adds a fault model, which provides the probability of a number of architectural faults in the interconnection network (e.g., data corruption, misrouting). These probabilities can be used to realistically inject faults in GARNET and faithfully evaluate the effectiveness of novel resilient NoC architectures.
2011-11-03Ruby: Remove some unused typedefsNilay Vaish
This patch removes some of the unused typedefs. It also moves some of the typedefs from Global.hh to TypeDefines.hh. The patch also eliminates the file NodeID.hh.

2011-05-23config: tweak ruby configs to clean up hierarchySteve Reinhardt
Re-enabling implicit parenting (see previous patch) causes current Ruby config scripts to create some strange hierarchies and generate several warnings. This patch makes three general changes to address these issues. 1. The order of object creation in the ruby config files makes the L1 caches children of the sequencer rather than the controller; these config ciles are rewritten to assign the L1 caches to the controller first. 2. The assignment of the sequencer list to system.ruby.cpu_ruby_ports causes the sequencers to be children of system.ruby, generating warnings because they are already parented to their respective controllers. Changing this attribute to _cpu_ruby_ports fixes this because the leading underscore means this is now treated as a plain Python attribute rather than a child assignment. As a result, the configuration hierarchy changes such that, e.g., system.ruby.cpu_ruby_ports0 becomes system.l1_cntrl0.sequencer. 3. In the topology classes, the routers become children of some random internal link node rather than direct children of the topology. The topology classes are rewritten to assign the routers to the topology object first.
2011-05-21garnet: use vnet_type from protocol to decide buffer depthsTushar Krishna
The virtual channels within "response" vnets are made buffers_per_data_vc deep (default=4), while virtual channels within other vnets are made buffers_per_ctrl_vc deep (default = 1). This is for accurate power estimates.
2011-05-18slicc: added vnet_type field to identify response vnets from othersTushar Krishna
Identifying response vnets versus other vnets will allow garnet to determine which vnets will carry data packets, and which will carry ctrl packets, and use appropriate buffer sizes (since data packets are larger than ctrl packets). This in turn allows the orion power model to accurately estimate buffer power.
2011-05-18garnet: rename and rearrange config parameters.Tushar Krishna
Renamed (message) class to vnet for consistency with rest of ruby. Moved some parameters specific to fixed/flexible garnet networks into their corresponding py files.

2011-04-28network: set the ExtLink bw to 16 bytesBrad Beckmann
Therefore all links by default are 16 bytes wide and thus work with Garnet's uniform link bandwidth assumption.
2011-04-28garnet: removed flit_width from RoutersBrad Beckmann
2011-04-28network: adjusted default endpoint bandwidthBrad Beckmann
The simple network's endpoint bandwidth value is used to adjust the overall bandwidth of the network. Specifically, the ration between endpoint bandwidth and the MESSAGE_SIZE_MULTIPLIER determines the increase. By setting the value to 1000, that means the bandwdith factor specified in the links translates to the link bandwidth in bytes. Previously, it was increasing that value by 10. This patch will likely require a reset of the ruby regression tester stats.
2011-04-28network: removed the unused network-wide latency paramBrad Beckmann
2011-04-28network: moved network config paramsBrad Beckmann
Moved the buffer_size, endpoint_bandwidth, and adaptive_routing params out of the top-level parent network object and to only those networks that actually use those parameters.
2011-04-28network: basic link bw for garnet and simple networksBrad Beckmann
This patch ensures that both Garnet and the simple networks use the bw value specified in the topology. To do so, the patch generalizes the specification of bw for basic links. This value is then translated to the specific value used by the simple and Garnet networks. Since Garent does not support non-uniformed link bandwidth, the patch also adds a check to ensure all bws are equal. --HG-- rename : src/mem/ruby/network/BasicLink.cc => src/mem/ruby/network/simple/SimpleLink.cc rename : src/mem/ruby/network/BasicLink.hh => src/mem/ruby/network/simple/SimpleLink.hh rename : src/mem/ruby/network/BasicLink.py => src/mem/ruby/network/simple/SimpleLink.py
2011-04-28network: convert links & switches to first class C++ SimObjectsBrad Beckmann
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

2011-04-28ruby: moved topology to the top network directoryBrad Beckmann
Moved the Topology class to the top network directory because it is shared by both the simple and Garnet networks. --HG-- rename : src/mem/ruby/network/simple/Topology.cc => src/mem/ruby/network/Topology.cc rename : src/mem/ruby/network/simple/Topology.hh => src/mem/ruby/network/Topology.hh

2011-04-15trace: reimplement the DTRACE function so it doesn't use a vectorNathan Binkert
At the same time, rename the trace flags to debug flags since they have broader usage than simply tracing. This means that --trace-flags is now --debug-flags and --trace-help is now --debug-help

2011-03-21This patch adds the network tester for simple and garnet networks.Tushar Krishna
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.
2011-03-01Ruby: Fix DPRINTF bugs in PerfectSwitch and MessageBufferNilay Vaish
At a couple of places in PerfectSwitch.cc and MessageBuffer.cc, DPRINTF() has not been provided with correct number of arguments. The patch fixes these bugs.
2011-02-23ruby: cleaning up RubyQueue and RubyNetwork dprintfsKorey Sewell
Overall, continue to progress Ruby debug messages to more of the normal M5 debug message style - add a name() to the Ruby Throttle & PerfectSwitch objects so that the debug output isn't littered w/"global:" everywhere. - clean up messages that print over multiple lines when possible - clean up duplicate prints in the message buffer
2011-02-14Ruby: Improve Change PerfectSwitch's wakeup functionNilay Vaish
Currently the wakeup function for the PerfectSwitch contains three loops - loop on number of virtual networks loop on number of incoming links loop till all messages for this (link, network) have been routed With an 8 processor mesh network and Hammer protocol, about 11-12% of the was observed to have been spent in this function, which is the highest amongst all the functions. It was found that the innermost loop is executed about 45 times per invocation of the wakeup function, when each invocation of the wakeup function processes just about one message. The patch tries to do away with the redundant executions of the innermost loop. Counters have been added for each virtual network that record the number of messages that need to be routed for that virtual network. The inner loops are only executed when the number of messages for that particular virtual network > 0. This does away with almost 80% of the executions of the innermost loop. The function now consumes about 5-6% of the total execution time.
2011-02-07Orion: Replace printf() with fatal()Nilay Vaish
The code for Orion 2.0 makes use of printf() at several places where there as an error in configuration of the model. These have been replaced with fatal().
