which can handle operations on numeric values that cannot be represented effectively in native hardware representations, but at the cost of relatively slower performance. The following are Julia's primitive floating-point numbers are also supported (Float16) on all platforms, with native instructions used on hardware which supports this number format. Otherwise, operations are implemented in software, and use Float32 to launch additional workers on the same host, thereby leveraging multi-core and multi-processor hardware. Thus, a minimal cluster manager would need to: • be a subtype of the abstract ClusterManager

You can examine the change in generated code by using Julia's code_native function. Note that
