[AccessD] Pi day

[John Colby]

To celebrate Pi day I downloaded PiFast and calculated Pi to 1 billion
digits.  On my laptop with 4 real and 4 virtual cores, using the disk for
intermediate results in some manner (unknown) it took 105 seconds to
calculate Pi to 10 million digits.

On my much more powerful 8 core 8 virtual cores laptop, it took 70 seconds.

OTOH  it took 7 seconds to compute without using the disk at all.

Then I tried to calculate 1 billion places without the disk and the program
just crashed.  Using the disk (SSDs on both computers) it took 58 minutes
or so.

Happy pi day.
