nprocs

nprocs()

Get the number of available processes.

Examples

julia> nprocs()
1

This example returns the number of available processes, which is typically the number of CPU cores on the machine. In this case, the result is 1, indicating that there is only one process available.

Common mistake example:

julia> nprocs([])
ERROR: MethodError: no method matching nprocs(::Array{Any,1})

In this example, the nprocs() function is mistakenly called with an argument of an empty array. The nprocs() function does not take any arguments, so passing in an array or any other argument will result in a MethodError. Make sure to call nprocs() without any arguments to get the number of available processes.
