[Gems-users] Zero L2 misses

[Rakesh Komuravelli <komurav1@xxxxxxxxxxxx>]

Hi,

I see L2 misses to be zero in the Ruby dump-stats. All other entries under L2_cache cache stats are zero too. This is for MESI_SCMP_bankdirectory protocol. I do see L1 D cache stats but I don't see any L1 I cache stats because I am not loading Opal. The versions and other parameters I am using are as follows:

Versions:

simics 3

gems 2.1.1

Simics commands before loading ruby:

instruction-fetch-mode instruction-fetch-trace,

istc-disable,

dstc-disable,

cpu-switch-time 1

Ruby commands:

ruby0.setparam g_NUM_PROCESSORS 16,

ruby0.setparam g_PROCS_PER_CHIP 16,

ruby0.setparam g_MEMORY_SIZE_BYTES 268435456,

ruby0.setparam g_NUM_L2_BANKS 16,

ruby0.setparam g_NUM_MEMORIES 16,

ruby0.setparam NUMBER_OF_VIRTUAL_NETWORKS 5,

ruby0.setparam_str g_CACHE_DESIGN NUCA,

ruby0.setparam_str g_NETWORK_TOPOLOGY FILE_SPECIFIED,

ruby0.setparam g_DATA_BLOCK_BYTES 64,

ruby0.init

Any help is greatly appreciated.

Thanks,

Rakesh
