My experience is that running two cores on a single machine slows it down a lot, owing to memory cache conflicts.
It probably depends on how you access memory.  If it's mostly local per process, it may not hurt much. rhhardin at mindspring.com rhhardin at att.net (either)

For n=6, the minimum smallest piece in an 11-piece solution equals 1/120,
like in
[1/120, 1/40, 1/30, 7/120, 3/40, 11/120, 13/120, 1/8, 17/120, 1/6, 1/6]

It would take about 37 days of single-core computations in Sage+Gurobi.
Luckily I run on a 40-core system and it took only about a day to establish
the above result.
