Explicitly set the amount of local host RAM (in MB) available to Bazel. Takes an integer, or "HOST_RAM", optionally followed by [-|*]<float> (eg. HOST_RAM*.5 to use half the available RAM).By default, ("HOST_RAM*.67"), Bazel will query system configuration to estimate amount of RAM available for the locally executed build actions and will use 67% of available RAM. Note: This is a no-op if --ram_utilization_factor or --local_resources is set.
