Hi Jieming, I have been updating the wiki so that I can point to it as soon as I release the patches. I am having trouble uploading images to the wiki. I get this error:
Warning: fopen(/z/www/htdocs/wiki/images/lockdir/jny8zw5whr3mvxbze7rj32hk8ghgbgf.lock): failed to open stream: Permission denied in /z/www/htdocs/wiki/includes/filebackend/lockmanager/FSLockManager.php on line 125 [51edc250] 2016-10-02 20:30:33: Fatal exception of type "MWException" It seems to be from the server hosting the wiki. Do you know how to resolve this? Thanks, Tushar On Oct 3, 2016, at 1:55 PM, Jieming Yin <bjm...@gmail.com<mailto:bjm...@gmail.com>> wrote: Hi Tushar, Thanks for addressing Zicong's comment. Do you feel comfortable checking in the patches? Jieming On Sat, Sep 24, 2016 at 9:18 AM, Krishna, Tushar <tus...@ece.gatech.edu<mailto:tus...@ece.gatech.edu>> wrote: I found the bug and fixed it. [Basically by default garnet should use the routing table, the src_outport and dst_inport names are for supporting special routing algorithms that the user may want to implement. The default routing algo was set to the user-specified one in the config file]. Thanks Zicong!

Can you send me the command you used that gave you the segmentation fault? src_outport and dst_inport are supposed to be optional parameters. I can add them in to MeshDirCorners_XY but want to find out why they gave an error. Thanks, Tushar Hi, Tushar, Thanks for your working garnet2.0, and the network becomes easier to use for researching. The command I used is showed as below: ./build/X86_MESI_Two_Level/gem5.debug \ configs/example/se.py \ --cmd=tests/test-progs/hello/bin/x86/linux/hello \ --cpu-type=detailed --ruby --num-cpus=16 \ --caches --cacheline_size=128 \ --l1i_size=16kB --l1i_assoc=2 \ --l1d_size=16kB --l1d_assoc=2 \ --l2cache --l2_size=128kB --l2_assoc=4 --num-l2caches=16 \ --topology=MeshDirCorners_XY --mesh-rows=4 \ --num-dirs=4 --mem-size=4GB \ --sys-clock=1GHz --ruby-clock=1GHz --cpu-clock=1GHz \ --maxinsts=10000 \ --network=garnet2.0 |tee m5out/runscript.log I test it on a latest changeset(fd783bff017c) which patched with rb35{49,50,54,55,56,57,58}.patch. In addition, I got the same segmentation fault running on my own gem5 project(based on a changeset several month before released). I checked the core file and found out nullptr at NetworkInterface.cc<http://networkinterface.cc><http://networkinterface.cc<http://networkinterface.cc/>>:178 caused the breakdown(a packet injected to vnet 0 incorrectly enqueued at NI 0). What's more, It works well in X86_MESI_Two_Level(Mesh_XY) and Garnet_standalone. When I add src_outport & dst_inport into MeshDirCorners_XY, it works as well as Mesh_XY. I hope the information are useful to your working.
