Hi all, First, I wanted to share my appreciation to the gem5 community for putting up the great documentation and slides. However, the example I tried has a few problems that may send users for a loop so I figure I would post it here to see if we can get some updated slides. For 64 socket SMP, 2-Level on-chip Caches, MOESI protocol, 32K L1s, 8MB L2 per chip, mesh interconnect the tutorial says to do:
./build/ALPHA_FS/m5.op configs/example/ruby_fs.py -n 64 -l1i_size=32kB -l1d_size=32kB -l2_size=512MB -num-l2caches=64 -topology=Mesh -timing But this leads to complaints with the options compiler, because "-" should be "--". If you fix this, Mesh.py on line 80 throws an exception because it expects a DMAController but finds a DirectoryController. The change here after looking in the mailing list is to add --num-dirs=64. The final functional version I show below: ./build/ALPHA_FS/m5.opt configs/example/ruby_fs.py -n 64 --l1i_size=32kB --l 1d_size=32kB --l2_size=512MB --num-l2caches=64 --topology=Mesh --timing --num-dirs=64 Also, please note that the example for "8 core CMP, 2-Level, MESI protocol, 32K L1s, 8MB 8-banked L2s, crossbar interconnect" has a similar problem with how the options were added where only a single '-' appears in the slides as opposed to '--'. I have not tested this example yet, but saw a similar format. Best, Rick
