how do you allocate/free memory without using the garbage

Use C malloc and free.
Does allocating and freeing memory using `GC.malloc` and
`GC.free` avoid D's garbage

I saw docs for std.experimental.allocator and also had found
automem library(https://code.dlang.org/packages/automem) for c++
style memory management via smartpointers.
From GC documentation std.experimental.allocator can not be used
for:
NewExpression
Array appending

Are you looking for parallel?

I have seen this, but I'm not sure how to use it.
Maybe:
float[][] maps = new float[#threads][resolution * resolution];
foreach(i, ref elem; parallel(maps)){
elem = generateTerrain(...);
}
Does this
Hello D-World,
I've written a small terraingenerator in D based on the
Hill-Algorithm.
To generate a terrain I only need to call the method
generateTerrain(...) which returns a float-Array containing the
height of each pixel (2D Array mapped with a 1D array with length
resolution^2).
