Benchmark structure for UInt classes #553

igormcoelho · 2019-01-16T16:01:06Z

Created a basic benchmark structure for UInt classes. Will help on discussion #552.

igormcoelho · 2019-01-16T16:03:25Z

@jsolman I created a sketch of testing classes for resolve the benchmark situation. We can merge this before, so we test lights and your proposal.

igormcoelho · 2019-01-16T16:06:40Z

@lightszero I created this basic testing structure to improve our discussions on the other thread. Right now, I couldn't see significant improvement on performance... In fact, it was slower on my initial measurements.

neo.UnitTests/UT_UIntBenchmarks.cs

+                uut_32_1[i] = new UInt256(base_32_1[i]);
+                uut_32_2[i] = new UInt256(base_32_2[i]);
+            }
+            Stopwatch sw0 = new Stopwatch();


Can you make a method that runs the stopwatch and takes a delegate with code to be benchmarked. The loop would occur in the passed delegate.

Since times are quite short... we need to measure them all together, if I measure one by one, system time will be bigger than timing itself.

No I wasn’t suggesting measure 1 by 1. I was suggesting a benchmark method that takes a delegate. The passed delegate has the code that loops 1 million times all in one call to the delegate.

oh!! nice! it would look better indeed for better isolation.

neo.UnitTests/UT_UIntBenchmarks.cs

+            {
+                uint* lpx = (uint*)px;
+                uint* lpy = (uint*)py;
+                for (int i = 8; i >= 0; i--)


Should actually be i=7

…ark.

igormcoelho · 2019-01-16T17:45:36Z

I guess the tests are ready.. that will also help future decisions in similar subjects.

jsolman

This is nice for a template for benchmark testing, but this test shouldn’t really be pushed to the master branch unless only the code that is being used is enabled for testing.

lightszero · 2019-01-17T09:27:18Z

this is not a good test case.
all test data is not equal.
now we set 50% data is equal,than you can see different.
@igormcoelho

    [TestInitialize]
    public void TestSetup()
    {
        int SEED = 123456789;
        random = new Random(SEED);

        base_32_1 = new byte[MAX_TESTS][];
        base_32_2 = new byte[MAX_TESTS][];
        base_20_1 = new byte[MAX_TESTS][];
        base_20_2 = new byte[MAX_TESTS][];

        for (var i = 0; i < MAX_TESTS; i++)
        {
            base_32_1[i] = RandomBytes(32);
            if (i % 2 == 0)
            {
                base_32_2[i] = RandomBytes(32);
            }
            else
            {
                base_32_2[i] = new byte[32];
                Buffer.BlockCopy(base_32_1[i], 0, base_32_2[i], 0, 32);
            }
            base_20_1[i] = RandomBytes(20);
            base_20_2[i] = RandomBytes(20);
        }
    }

shargon · 2019-01-17T10:10:45Z

For benchmarks i ussually use https://benchmarkdotnet.org/articles/overview.html with great results

lightszero · 2019-01-17T10:56:37Z

now result is like this，with 50% equal data

Elapsed=00:00:01.1170521 Sum=-1244
Elapsed=00:00:01.0273095 Sum=-1244
Elapsed=00:00:00.4392158 Sum=-1244
Elapsed=00:00:00.3674855 Sum=-1244

vncoelho · 2019-01-17T11:35:04Z

Men, you are all genius.
Nice catch about the difficulty of the task, @lightszero.

igormcoelho · 2019-01-17T12:52:26Z

Nice observation @lightszero! Perhaps 50% equals is a better benchmark indeed.

igormcoelho · 2019-01-17T13:05:16Z

Please let's keep 1 million maximum... or it breaks my computer :)

igormcoelho · 2019-01-17T14:30:12Z

Implemented and inlined UInt160 option.... better than pure uint, no loops kkkkkkkkk

        private unsafe int code3_UInt160CompareTo(byte[] b1, byte[] b2)
        {
            // LSB -----------------> MSB
            // --------------------------
            // | 8B      | 8B      | 4B |
            // --------------------------
            //   0l        1l        4i
            // --------------------------
            fixed (byte* px = b1, py = b2)
            {
                uint* lpxi = (uint*)px;
                uint* lpyi = (uint*)py;
                if (lpxi[4] > lpyi[4])
                    return 1;
                if (lpxi[4] < lpyi[4])
                    return -1;

                ulong* lpx = (ulong*)px;
                ulong* lpy = (ulong*)py;
                if (lpx[1] > lpy[1])
                    return 1;
                if (lpx[1] < lpy[1])
                    return -1;
                if (lpx[0] > lpy[0])
                    return 1;
                if (lpx[0] < lpy[0])
                    return -1;
            }
            return 0;
        }

vncoelho · 2019-01-17T17:28:20Z

I think it is good like this. The idea of having comparisons ensure safety because the results of those 3 tries are compared against each other.

jsolman · 2019-01-17T18:46:57Z

I should have noticed the data wasn’t the same across runs. Nice catch @lightszero

@igormcoelho did you calculate the amount of RAM used for this test? is not excessive?

Travis should not run this normally. Benchmarks should not be enabled normally in unit tests that run after each commit; there is no benefit also because the test doesn’t fail if the benchmark were to take longer than a threshold.
