CONFIGURATION

internal memory for sorting = 650 MB

EdgeVector default block size = 2048 KB
EdgeVector default #pages = 1
EdgeVector default page size = 4 block(s)

MST vector block size = 2048 KB
MST vector #pages = 1
MST vector page size = 4 block(s)

Duplicates are removed.

The input is randomized.

buckets implementation

external bucket block size = 512 KB
external bucket page size = 1 block(s)

internal buckets: no of blocks = 1500000
internal buckets: edges per block = 8
