Dear All,
I am trying to make a simple code run in parallel. The parallel

First, the parallel features I am using:

The size of your task are way too small.
To win something with OS threads, you must think of tasks that
takes on the order of milliseconds rather than less than 0.1ms.

It's usually a much better idea to parallelize the outer loop.

In other words, the OP can adjust work unit size. It is on the of
Thank you, folks, for your hints and suggestions!
Indeed, I re-wrote the code and got it substantially faster and
well paralleled.
Insted of making inner loop parallel, I made parallel both of
them. For that I had to convert 2d index into 1d, and then back
to 2d. Essentially I had to calcula
Yes, did the same and it worked. The amazing thing is that the

Well its not a type system issue.
Making u = n, that'll returns true.
So the problem almost certainly lies with IEEE-754.
They are horrible to compare (float/double).
Unfortunately you are stuck calling functions like isClose to compare.

There is 'nm' on Posix systems that lists symbols in object files
(including libraries and programs).

Look at the `emerging` languages, which are not crazy about
