I did try the longer runs. The result is the same (i.e. no apparent parallelism).

Here's a snapshot w/8 kernels.

$ bin/host 100000000 8

Task:0 complete (3437.999 ms)

Task:1 complete (6875.815 ms)

Task:2 complete (10313.553 ms)

Task:3 complete (13751.281 ms)

Task:4 complete (17189.009 ms)

Task:5 complete (20626.756 ms)

Task:6 complete (24064.509 ms)

Task:7 complete (27502.250 ms)

Time: 27502.254 ms (3437.782 ms / kernel)

Sum 0-100000000.000000 (step 1.000000) = 5000000050000000.000000
