Hallo! I would like to know how big an "UArray (100,100) Double" is (approximately) in Bytes. And how much heap will the program consume for it. (I mean does the garbage collector need this size, or double the size, or what?) Thanks, Andreas

I guess you mean: (accumArray const 0.0 ((1, 1), (100, 100)) []) :: UArray (Int, Int) Double It should take about 100 * 100 * 8 = 80000 bytes .
And how much heap will the program consume for it. (I mean does the garbage collector need this size, or double the size, or what?)
About the same. I just checked that GHC allocates it as a big object, so the array isn't copied during GC. Best regards Tomasz
