Hi Pritha, The warnings you mentioned are expected and can be ignored as long as they only complain about Ruby Sim Objects. The reason for them is the checkpoint you created using normal ALPHA FS, only checkpointed the Sim Objects used by normal ALPHA FS, but when a Ruby enabled system loads that checkpoint, it will search for information associated with Ruby Sim Objects.
The fake ports you mentioned are created to approximate the Tsunami chip set. See src/dev/alpha/Tsunami.py for more info. I have never seen instructions being retried when using Ruby. To my knowledge, RubyPort will never ask for any request to be retried. Could you provide more information? Brad From: m5-dev-boun...@m5sim.org [mailto:m5-dev-boun...@m5sim.org] On Behalf Of Pritha Ghoshal Sent: Tuesday, July 13, 2010 10:27 AM To: M5 Developer List Subject: [m5-dev] Using Ruby to run run from PARSEC checkpoint Hi, I am trying to use the parsec benchmark to create checkpoints using normal ALPHA FS (without ruby), and then trying to run with ALPHA_FS_MESI_CMP_Directory or ALPHA_FS_MOESI_Hammer binaries. Though the checkpoint complete execution successfully if I run with normal ALPHA_FS without ruby, they seem to hang while running ruby based Alpha. Also in the beginning I get the a lot of warnings like the following: warn: Not unserializing 'system.ruby.network.topology.ext_links2.ext_node.L2cacheMemory': no section found in checkpoint. For more information see: http://www.m5sim.org/warn/dc3e87f8 warn: Not unserializing 'system.ruby.network.topology.ext_links2.ext_node.sequencer.icache': no section found in checkpoint. For more information see: http://www.m5sim.org/warn/dc3e87f8 warn: Not unserializing 'system.ruby.network.topology.ext_links2.ext_node.sequencer.dcache': no section found in checkpoint. For more information see: http://www.m5sim.org/warn/dc3e87f8 warn: Not unserializing 'system.ruby.network.topology.ext_links1': no section found in checkpoint. For more information see: http://www.m5sim.org/warn/dc3e87f8 warn: Not unserializing 'system.ruby.network.topology.ext_links1.ext_node': no section found in checkpoint. For more information see: http://www.m5sim.org/warn/dc3e87f8 I think the components are not being set up properly, is that what it means? When I enabled the config flag, I realised these are the ports being created: 0: system.piobus-p3: setting peer to system.tsunami.fake_sm_chip-pioport 0: system.tsunami.fake_sm_chip-pioport: setting peer to system.piobus-p3 0: system.piobus-p4: setting peer to system.tsunami.fake_uart1-pioport 0: system.tsunami.fake_uart1-pioport: setting peer to system.piobus-p4 0: system.piobus-p5: setting peer to system.tsunami.fake_uart2-pioport 0: system.tsunami.fake_uart2-pioport: setting peer to system.piobus-p5 Could someone help me regarding this? Why are the ports created being fake? Also for this reason, the instructions are not going through and the same instruction keeps on looping in retry mode. Thank you Pritha
