Subject: | [Gems-users] Cache Parameters |
Hello, I'm trying to set Opal up to simulate a cache heiarchy with the following parameters: Cache-to-cache latency - 400 cycles L1 hit latency - 2 cycles L2 hit latency - 24 cycles Memory access latency - 460 cycles The latter two seem obvious: opal0.setparam L2_LATENCY 24 opal0.setparam MEMORY_DRAM_LATENCY 460 The L1 latency is more problematic... the options are a bit similar. Is the opal0.setparam L1_FILL_BUS_CYCLES option what I want? What should L2_FILL_BUS_CYCLES be in this case? I've been going through the default config files and also the code itself but am a bit confused by what's going on... Thanks, Vince |
