cpu-check's Introduction

CPU Check

CPU torture test designed for SMP systems, attempting to find CPU hardware faults, focusing primarily on the x86_64 architecture.

The basic operation is to:

Run threads with affinity fixed to each logical CPU.
Generate a chunk of random data, either dictionary based text, or random binary data.
Run a number of checksum/hash algorithms over the data, store their results.
Compress the data via one of (zlib, ...).
Encrypt the data via AES-256-GCM.
Copy the data ('rep movsb' on x86, else memcpy).
Switch affinity to an alternate logical CPU.
Decrypt.
Decompress.
Run checksum/hash algorithms and compare with stored results.

Algorithms are chosen to exercise various hardware extensions. Eg. on x86_64, SSE4.2, AVX, etc.

Prerequisites:

Designed to run under Unix/Linux OS.

cmake: https://cmake.org/
zlib
OpenSSL
Abseil-cpp: https://github.com/abseil/abseil-cpp

Note that Abseil must be built with the C++17 standard and include the StatusOr package (release 2020_09_23 or later).

Building

sh$ git clone --recursive  https://github.com/google/cpu-check.git
sh$ cd cpu-check
sh$ mkdir build
sh$ cd build
sh$ cmake ..
sh$ make

Options

Some options have been implememented that affect the build, which may be passed to cmake via, eg:

cmake -DCMAKE_BUILD_TYPE=(Debug|Release)

CMAKE_BUILD_TYPE=(Release|Debug)
USE_CLANG=(ON|OFF)
BUILD_STATIC=(ON|OFF)

TODO:

Use git submodules for:
- highwayhash: https://github.com/google/highwayhash
- crc32c: https://github.com/google/crc32c
- cityhash: https://github.com/google/cityhash
- brotli: https://github.com/google/brotli
- gipfeli: https://github.com/google/gipfeli
Expand encryption coverage - find those algorithms that stress the HW.
Flags to enable/disable steps, eg. encryption.
Flags controlling min/max buffer size.
Use cpuid to dynamically select appropriate instruction set extensions.
Query ACPI/cpuid for more meaningful CPU identification.
Extra x86_64 instruction coverage:
- movnti (SSE2 mov doubleword with non-temporal hint)
- prefetch*
- movbe (mov with byte swap)
Consider floating point tests?
Keep stats on corruptions (eg. buffer lengths/alignments, detection means (crc32), etc).
Try to narrow down corruptions automatically.

cpu-check's Issues

make fails with linker errors in abseil package

I am trying to compile this on Centos 8 machine. I had to install abseil-cpp-devel, zlib-devel, zlib-static and openssl-devel packages via dnf command. The cmake step passes but the make step fails -

/home/$ cmake -DOPENSSL_ROOT_DIR=/usr/local/ssl/ -DOPENSSL_INCLUDE_DIR=/usr/local/ssl/include/openssl  ..

My doubts are on the abseil-cpp package. The README mentions -
Note that Abseil must be built with the C++17 standard and include the StatusOr package (release 2020_09_23 or later).
I see that in CMakeLists.txt, we already set the C++ version to 17 - https://github.com/google/cpu-check/blob/master/CMakeLists.txt#L52.
The installed abseil-cpp shows that the version is indeed 2020-09-23 -

Installed Packages
Name         : abseil-cpp
Version      : 20200923.3

Source       : abseil-cpp-20200923.3-1.el8.src.rpm

Could someone please help with this? Any reference to existing documentation for generating the cpu-check binary would be great. Thanks.
