[Gems-users] Garnet startup

[harry y <yh_0116@xxxxxxxxxxx>]

Hi Gems guys,
I am attempting to build a simple 2x2 mesh network using Garnet, but kind of lost in the process. Could anyone give guidance on my procedure below?
 
1. I build a MSI_MOSI_CMP_directory protocol.
2. And in rubyconfig.defaults I set the following parameters
 
g_NUM_PROCESSORS: 4
g_NUM_L2_BANKS: 4
g_NUM_MEMORIES: 1
g_PROCS_PER_CHIP: 1
 
and garnet related following the GEMS wiki
 
g_NETWORK_TOPOLOGY: FILE_SPECIFIED
g_GARNET_NETWORK: true
g_DETAIL_NETWORK: true
g_NETWORK_TESTING: false
g_FLIT_SIZE: 16
g_VCS_PER_CLASS: 1
g_BUFFER_SIZE: 4
g_CACHE_DESIGN: MESH
recompiled ruby.
 
3. Then I use the NetworkFileMaker.py at $GEMS/ruby/network/simple/Network_Files to generated a topology file named "MESH_Procs-4_ProcsPerChip-1_L2Banks-4_Memories-1.txt"
I am not sure whether those are enough to create a network. Several doubts are:

1. Which file is the FILE_SPECIFIED pointed to? Should it be the one generated above? How does it recognize it?
2. How should I quickly test the network? Should I follow the gen-script.py and build workload to test it? Actually I run the generated tester.exec, but it give the following error:
 
============================================================================

Does it mean Garnet is not properly configured?

Since I am new to GEMS, any guidance is highly appreciated. Thanks!

Best Regards,
Harry
