[PATCH 3/3] MIPS: Loongson64: Enlarge cross-package node distance

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



NUMA node distances affect the NUMA balancing behaviors. The cost of
cross-package memory access is very high, and our benchmarks show that
200 is a more appropriate value than 100 (for cross-package numa node
distance) on Loongson64 platforms, so enlarge it.
