Build machines boasting
#1
I'd like people to contribute to this thread, telling us what their machine's specs are and how long it takes to build Cuberite on that machine (from scratch), plus what compiler they use. In the end, it might be a good benchmark for deciding what kind of hardware to get for upgrades (there are not too many compilation-related benchmarks in the real world).

The results
are in this Google Sheets document: https://docs.google.com/spreadsheets/d/1...sp=sharing



On Windows, use this script to measure the time (attached as timed_run.zip):
@echo off
echo Started: %time% > time.log
echo Cloning from git...
mkdir Cuberite
cd Cuberite
git clone --recurse-submodules https://github.com/cuberite/cuberite .
if errorlevel 1 goto Error
echo Cloned: %time% >> ..\time.log

echo Running CMake...
mkdir VS
cd VS
cmake -DBUILD_TOOLS=1 -DSELF_TEST=1 ..
if errorlevel 1 goto Error
echo CMaked: %time% >> ..\..\time.log

echo Building...
cmake --build .
if errorlevel 1 goto Error
cd ..\..
echo Built: %time% >> time.log
echo All done successfully
goto Finished

:Error
echo An error occurred, timings are invalid

:Finished

On Linux, try this script (courtesy of @paradise from Discord and @Mathias; attached as measure_time.zip):
#!/usr/bin/env bash

echo "Started: `date +%H:%M:%S`" > time.log
echo "Cloning from git..."
mkdir Cuberite
cd Cuberite
git clone --recurse-submodules https://github.com/cuberite/cuberite . || (echo \'An error occurred, timings are invalid\' && exit 1)
echo "Cloned: `date +%H:%M:%S`" >> ../time.log

echo "Running CMake..."
mkdir VS
cd VS
cmake -DBUILD_TOOLS=1 -DSELF_TEST=1 .. || (echo \'An error occurred, timings are invalid\' && exit 1)
echo "CMaked: `date +%H:%M:%S`" >> ../../time.log

echo "Building..."
MAKEFLAGS="" cmake --build . -j $(nproc) || (echo \'An error occurred, timings are invalid\' && exit 1)
cd ../..
echo "Built: `date +%H:%M:%S`" >> time.log
echo "All done successfully"

Corrected the linux shell script:
  • cmake --build used only one core, added j-flag and nproc to use all cores
  • Changed¬†time output to e.g. 14:30:25
  • Added missing brackets, script would exit after git clone
Code:
#!/usr/bin/env bash

echo \'Started: `date +%H:%M:%S`\' > time.log
echo \'Cloning from git...\'
mkdir Cuberite
cd Cuberite
git clone --recurse-submodules https://github.com/cuberite/cuberite . || (echo \'An error occurred, timings are invalid\' && exit 1)
echo \'Cloned: `date +%H:%M:%S`\' >> ../time.log

echo \'Running CMake...\'
mkdir VS
cd VS
cmake -DBUILD_TOOLS=1 -DSELF_TEST=1 .. || (echo \'An error occurred, timings are invalid\' && exit 1)
echo \'CMaked: `date +%H:%M:%S`\' >> ../../time.log

echo \'Building...\'
cmake --build . -j $(nproc) || (echo \'An error occurred, timings are invalid\' && exit 1)
cd ../..
echo \'Built: `date +%H:%M:%S`\' >> time.log
echo \'All done successfully\'

When using -j with cmake --build, I get way too many clang++ processes (tens of them, on my 4-core system), which end up contending for RAM, rather than CPU. The compilation time is worse then, and sometimes it even fails.

Found out why. I have MAKEFLAGS="-j8" in my .profile , so any "make" invokation causes multiplied builds. Fixing the script to account for that...

I've compiled the results into a Google docs sheet. Keep the results coming Smile Also, those already present, please try to provide the items missing in the report.
