remotecall_wait

remotecall_wait(func, id, args...)

Perform wait(remotecall(...)) in one message.

Examples

1. Wait for a remote function call to complete:

   julia> result = remotecall_wait(sqrt, 2, 4)
   2.0

   This example performs a remote function call to compute the square root of 4 on process 2. The remotecall_wait function waits for the result of the remote call and returns the computed value.

2. Passing multiple arguments to the remote function:

   julia> result = remotecall_wait(+, 3, 1, 2)
   3

   In this example, the remote function call adds the numbers 1 and 2 on process 3. The remotecall_wait function waits for the result and returns the sum.

3. Using a user-defined function remotely:

   julia> function myfunction(x)
             return x^2 + 3x + 2
         end
   julia> result = remotecall_wait(myfunction, 4, 5)
   37

   Here, the remotecall_wait function executes the myfunction on process 4 with the argument 5. It waits for the result and returns the computed value.

Common mistake example:

julia> result = remotecall_wait(sqrt, 10)
ERROR: UndefVarError: sqrt not defined

In this example, the sqrt function is not defined in the current scope. Ensure that the required function is imported or defined before using remotecall_wait with that function.
