Could someone explain it ? It seems that tgts_per_mshr = 1 equals to tgts_per_mshr = Infinite large. | tgts_per_mshr | 1 | 2 | 4 | 8 | 16 | 32 | | 401.bzip2 running time | 0.0450 | 0.072 | 0.063 | 0.046 | 0.0453 | 0.0452 | | 403.gcc running time | 0.0141 | 0.015 | 0.015 | 0.014 | 0.0143 | 0.0142 | | | | | | | | | | | | | | | | | Best regards.
