QUESTION

Why does my empty loop run twice as fast if called as a function, on Intel Skylake CPUs?

Asked 2021-Jun-08 at 02:35

I was running some tests to compare C to Java and ran into something interesting. Running my exactly identical benchmark code with optimization level 1 (-O1) in a function called by main, rather than in main itself, resulted in roughly double performance. I'm printing out the size of test_t to verify beyond any doubt that the code is being compiled to x64.

I sent the executables to my friend who's running an i7-7700HQ and got similar results. I'm running an i7-6700.

Here's the slower code:

The slow version:

Note that the sub rax, 1 \ jne pair goes right across the boundary of the ..80 (which is a 32byte boundary). This is one of the cases mentioned in Intels document regarding this issue namely as this diagram:

So this op/branch pair is affected by the fix for the JCC erratum (which would cause it to not be cached in the µop cache). I'm not sure if that is the reason, there are other things at play too, but it's a thing.

In the fast version, the branch is not "touching" a 32byte boundary, so it is not affected.

There may be other effects that apply. Still due to crossing a 32byte boundary, in the slow case the loop is spread across 2 chunks in the µop cache, even without the fix for JCC erratum that may cause it to run at 2 cycles per iteration if the loop cannot execute from the Loop Stream Detector (which is disabled on some processors by an other fix for an other erratum, SKL150). See eg this answer about loop performance.

To address the various comments saying they cannot reproduce this, yes there are various ways that could happen:

Whichever effect was responsible for the slowdown, it is likely caused by the exact placement of the op/branch pair across a 32byte boundary, which happened by pure accident. Compiling from source is unlikely to reproduce the same circumstances, unless you use the same compiler with the same setup as was used by the original poster.
Even using the same binary, regardless of which of the effects is responsible, the weird effect would only happen on particular processors.

ANSWER

Answered 2021-Jun-02 at 07:56

The main problem is the way you are returning the numeric values. x.number.values will return an array of shape (n_samples,) which the FeatureUnion object will try to combine with the result of the transformation of the text features later on. In your case, the dimension of the transformed text features is (n_samples, 98) which cannot be combined with the vector you get for the numeric features.

An easy fix would be to reshape the vector into a 2d array with dimensions (n_samples, 1) like the following:

ANSWER

As stated here, nested parameters must be accessed by the __ (double underscore) syntax. Depending on the depth of the parameter you want to access, this applies recursively. The parameter use_idf is under:

features > text_features > tfidf > use_idf

So the resulting parameter in your grid needs to be:

Micropython: [Errno 19] ENODEV but i2c.scan() returns proper address

Asked 2021-May-26 at 22:27

I am currently using an SRF-10 sensor connected to an esp32. It's being powered by 5V and I am using a level converter to bring down the voltage to 3.3V to be able to use it on the esp32. Both the SCL and SDA have a 1.8K pull up resistor as recommended on the datasheet. I have written the following script to try to get a read from the sensor. I am not entirely sure if it is correct but soon as it reaches line 16 I get an error saying [Errno 19] ENODEV. Eveything I could find suggests that the i2c connection isn't working properly but when I run i2c.scan() it returns the sensor address so I am guessing connections aren´t the problem. My script is as follows:

TestBench I2C Slave SDA won't go low

Asked 2021-May-17 at 17:21

I'm trying to write an I2C Slave and test it in isolation.

I have a simulation that should be pulling SDA low when write_ack is high (Also highlighted by the red dots). However, you can see that SDA remains the same.

Part of me thinks it's to do with the way I'm testing with the force methods and the delays.

Any help appreciated.

I have found the keyword release which seems to help.

Code below & EDA Playground is here: https://edaplayground.com/x/6snM

ANSWER

Answered 2021-May-17 at 17:20

Instead of using force, a more conventional approach is to add a tristate buffer to the testbench, just like you have in the design.

For SDA, create a buffer control signal (drive_sda) and a testbench data signal (sda_tb). Use a task to drive a byte and wait for the ACK.

Since SCL is not an inout, there is no need for a pullup, and it can be directly driven by clk.
