QUESTION
Why does the following effectivly unused line (in the method: getAllDefinedVars) have an impact on the end result:
List collect = allVars.stream().filter(v -> false).collect(Collectors.toList());
If I remove the whole method and the one line of code, which is calling this method (first line in generateOneSetOfBools), I get an other result in the end.
I would expect such a behavior if...
- the mentioned line had an impact on the List allVars or any other variable
- the result of the stream would be used
As far as I can see, none of this happens. Therefore a removal of this whole method should have no impact on the result.
To convince yourself you can run the main the first time with the method containing the stream and the second time without this method and then compare the output.

Answered 2020-Aug-07 at 06:41The difference in results you're getting has nothing to do with the line List collect = allVars.stream().filter(v -> false).collect(Collectors.toList());
. The problem is that your algorithm is non-deterministic. I've taken your code and run it multiple time for the same input:

I'm attempting to create a rudimentary "DVR" for an HTML5 video element by utilizing MediaRecorder
, MediaSource
, and SourceBuffer
. At the moment this is just a proof of concept. However since many projects like HLS.js take advantage of the HTML5 video element, I believe this would have wide-spread value.
Here's the gist of my code:

QUESTION
I want to pass a variable as a shared variable in openmp parallel code but I am not exactly sure what should I do to pass a structured variable into shared variable. Here is my code: I am not sure if this is the right way to do this or not:
...ANSWER
Answered 2017-Aug-21 at 20:56There are no arrays in your struct
. There are only pointers. lvl
is also just a pointer. The data sharing clauses (e.g. shared
) only applies to the variable itself (the address lvl
points to).
By the way, if you don't specify a data shared attribute, then variables defined outside the scope of parallel regions are implicitly shared
. Variables defined inside are implicitly private
. It is advisable to always define variables as locally as possible, it makes it easier to write correct code.
For example private variables, such as k
are not initialized within the parallel region.
