indexpids
indexpids(S::SharedArray)
Returns the index of the current worker into the pids
vector, i.e., the list of workers mapping the SharedArray
Examples
In the Julia programming language, the function indexpids(S::SharedArray)
is used to retrieve the index of the current worker within the pids
vector, which represents the list of workers mapping the SharedArray.
Here are some examples of how to use this function:
-
Get the index of the current worker:
julia> using Distributed, SharedArrays julia> S = @distributed SharedArray{Float64}(10); julia> indexpids(S) 2
This example shows how to obtain the index of the current worker for a specific SharedArray
S
. In this case, the result is2
, indicating that the current worker has index 2 within thepids
vector. - Use the index to perform task-specific operations:
julia> function process_data(S::SharedArray) worker_index = indexpids(S) if worker_index == 1 # Perform some computation only on the first worker println("Performing computation on the first worker") else # Perform a different computation for other workers println("Performing computation on worker $worker_index") end end julia> S = @distributed SharedArray{Int}(4); julia> @distributed for i in eachindex(S) process_data(S) end
In this example, the
indexpids
function is used to determine the worker index within thefor
loop. Based on the worker index, different computations can be performed on different workers.
It's important to note that the indexpids
function is specifically used with SharedArray
objects and within a distributed computing context.
