Go up one level in this thread
I am attaching the SMP results for 1, 2 and 4 cpus, for the first 12 BS2830
positions.
Vincent apparently wanted to pick and choose to produce a set of positions
Crafty does
badly on. I prefer to take a random set of positions, in this case the first 12
BS2830's
without any attempt to "pick the best or the worst."
Here's the results, including the edited log files. I deleted all output for
searches
less than 9 plies deep, and I deleted most of the statistics (EGTB probes, SMP
stuff,
etc) to make it as short as possible. It still turns out to be a _long_ post.
Here we go:
(this was also posted to rec.games.chess.computer since Vincent likes to make a
fool of
himself there as well as here).Here is the data produced by running the first 12
BS2830
positions thru Crafty, using one, two and four processors
on a quad 550 xeon box. The first 12 lines are the raw times
needed to search to a depth of ten plies for each of the 12
positions, using 1, 2 and 4 processors.
Raw times:
1cpu 2cpus 4cpus
1. 19.9 15.5 11.9
2. 171.0 132.0 79.0
3. 90.0 51.4 28.3
4. 3.5 2.1 1.4
5. 78.0 42.8 21.0
6. 0.4 0.2 0.2
7. 0.4 0.2 0.2
8. 39.0 19.0 16.2
9. 18.2 9.9 5.5
10. 119.0 59.4 36.5
11. 29.2 15.4 8.2
12. 72.0 40.3 23.3
Speedup per position:
2cpu 4cpu
1. 1.3 1.7
2. 1.3 2.2
3. 1.8 3.2
4. 1.6 2.6
5. 1.8 3.7
6. 2.1 2.3
7. 1.8 1.6
8. 2.0 2.4
9. 1.8 3.3
10. 2.0 3.3
11. 1.9 3.5
12. 1.8 3.1
----- -----
avg 1.8 2.7
The above average weighs every position equally. An alternative
way is to add all the times in the columns, and then divide the
one cpu total by the two cpu total (or the 4 cpu total) which
weights the positions that took longer, higher. That gives the
following speedup numbers.
2cpu 4cpu
avg 1.6 2.8
If I were trying to do this for a paper, I would have run the
test a bit differently, because at least 2 of the 12 positions
were not searched deeply enough for reasonable parallel comparison,
since 6 and 7 took .4 seconds each, compared to almost three minutes
for number 2. However, I didn't think Vincent was worth going to
a lot of trouble, since he has these sorts of fantasies from time
to time.
Also note that I ran these twelve positions once with 1 processor,
once with 2, and once with 4. I didn't do my usual run 4-8 times
and average to smooth out the SMP variability, again because (a)
I don't think Vincent is worth the trouble and (b) no amount of
data is going to bring him out of his imaginary world anyway. I
ran the test this was so that I could do them quickly and get this
out of the way.
If anybody is interested in the 4 cpu test output, I'll be happy to
post that as well. The data below is raw, but edited. I deleted the
output for any searches < 9 plies deep, plus I deleted some of the
statistics output at the end of each search, to limit the total
length.
Feel free to make any comments you choose.
Vincent can feel free to once again "run and hide" when data doesn't
support his wild claims and insults.
As always...
Finally, here is the raw data as produced by the one and two
processor searches. I can post the 4 processor data if anyone
thinks it is interesting, but the post is going to be pretty long
as it is.

If a line above is missing or duplicated, let me know. I had to cut/paste

into this browser
window (that I know of).
