thank you!! That should get me going

I guess it is generally smarter to try and work around locks, right? To avoid threads waiting for each other?

Hallo everyone, I need to process a huge amount of data, organized in a 2d grid, like a bitmap. its more than 25 million data sets so I wanted to use ParallelFor for this.

However, the problem is: While I can iterate over the grid to get data to process, I need to write the results from processing each dataset into several other datasets in the grid (advection). So, if i just use parallelFor, there will likely be write access to the same datasets by several threads simultaneously.

What is the best way to do this?

thank you!
