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:

...

ANSWER

Answered 2021-Jun-07 at 22:21

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-03 at 14:30

This is what I meant with this comment

though boost::system::system_error could invite issues back

The trouble is, error categories are global singleton instances, with object identity (i.e. compared for equality by their address).

You'r ending up with multiple instances in multiple modules. The usual solution is to

dynamically link to Boost System, so all libraries use the same copy (this does however sometimes run into initialization order issues)
if that doesn't solve it, make sure all modules actually load the same library (version?)
In recent boosts I think there's the option to build Boost System completely header-only. This may or may not involve new-fangled C++14 inline, I haven't checked.

If all else fails, do your own translation. There's related issues that might give you ideas:

Is it possible to convert a boost::system::error_code to a std:error_code?
Do note that exceptions may run into very similar issues due to RTTI not necessarily matching; exceptions need to be exported types and linked dynamically from the same module for the exception handlers to match the thrown runtime type id.

Is it normal or expected to compare only errorCode.value() against enums?

No it is not. According to some sources Boost as well as standard library promise to map generic error category to errc which is standard - so you could do that, but you still have to figure out whether that is the category, so doesn't help your scenario.

By looking at the error message, you are currently executing the program in C:\Users\{username} directory however your source code file helloworld.cpp is present in C:\Users\{username}\OneDrive\Desktop folder.

use cd "C:\Users\{username}\OneDrive\Desktop" in your terminal to navigate to the folder and then run the g++ helloworld.cpp -o helloworld command. After that run .\helloworld to run your program.

Note that if you using VS code to build your program as mentioned here, then you only have to execute the .\helloworld command to run it.

Can you update isolated components of MinGW?

Asked 2021-May-18 at 18:29

After installing MinGW-w64 on Windows 10, can you update single programs, like GDB alone (without updating the whole MingGW-w64 version)?

If so, how do you do it?

Thanks in advance

...

ANSWER

Answered 2021-May-18 at 18:29

A lot of those tools have dependencies (in the form of .dll files) and those dependencies have dependencies, etc...

So just replacing the .exe file is usually not the solution (unless it's a staticaly build .exe with no .dll dependencies), and overwriting .dll files that come with the new version mahy break other .exe and .dll files' dependencies.

In conclusion: it's not a good idea unless you keep the single program (like GDB) in a seperate directory.

The https://winlibs.com/ standalone build of MinGW-w64 includes recent versions of tools like GDB, and is always distributed as a whole package to avoid the issues above. Such package is created by building all the components and their dependencies from source.

I found the solution, if you are first time using PostgreSQL and new to SQL stuff, probably there is some python module not installed. Go to the folder C:(YourUserFolder)\PostgreSQL\pgAdmin 4\web and run setup.py using terminal. It will list down the module missing when you run. Install the modules and run again to see which other module is missing. Or you can use an IDE that can check which module that is not install in the _ init _.py files in the "PostgreSQL\pgAdmin 4\web\pgadmin" folder.
