04_ExecuteIndirect crash on macOS

[camots]

I've tested the Unit Tests on my Mac Pro 2010 / Vega 56 running MacOS Mojave 10.14.4. Xcode: Version 10.2.1 (10E1001) The examples are running fine except the 04_ExecuteIndirect.

It crashes directly at the beginning of void AsteroidSimulation::Init(uint32_t rngSeed, uint32_t numAsteroids, uint32_t numMeshes, uint32_t vertexCountPerMesh, uint32_t textureCount)

The error reported by the debugger is: Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)

Can anybody help?

Regards

Thanks for the feedback. We are looking into this ... should be fixed with the next release.

[wolfgangfengel]

This should be fixed ... please let us know.

I tried the updated version, however, it crashes at the exact same location with the same error message:

Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)

Best regards

Could we get repro steps? Does it happen when initializing the app ? Is there a log file and call stack you could share? We can't seem to replicate this locally at the moment.

Thanks

[camots]

Yes, it happens in the initialisation phase. The debugger stops at void AsteroidSimulation::Init(uint32_t rngSeed, uint32_t numAsteroids, uint32_t numMeshes, uint32_t vertexCountPerMesh, uint32_t textureCount)

All variables have unreasonable values. For example numAsteorids is 352400800 I can provide any information from the debugger.

For example the state of the numAsteorids class when the crash occurred in Thread 1 in method void AsteroidSimulation::Init:

Great, we'll look at this. Is there also a log file next to the built application ?

[camots]

Yes there is. It's content is The-Forge/Examples_3/Unit_Tests/macOS Xcode/Bin/Debug/04_ExecuteIndirect.log.

It's content is:

[ Fri Apr 26 07:50:54 2019 ] INFO: Opened log file /Volumes/home/*/work/The-Forge/Examples_3/Unit_Tests/macOS Xcode/Bin/Debug/04_ExecuteIndirect.log [ Fri Apr 26 07:50:54 2019 ] INFO: [initRenderer] Current Gpu Name: AMD Radeon RX Vega 56 [ Fri Apr 26 07:50:54 2019 ] INFO: [initRenderer] Current Gpu Vendor ID: 0x1002 [ Fri Apr 26 07:50:54 2019 ] INFO: [initRenderer] Current Gpu Model ID: 0x687f

Assuming you follow these requirements:

macOS Requirements: macOS Mojave 10.14.4 beta (18E174f)

Xcode 10.2 beta (10P82s)

The Forge is currently tested on the following macOS devices:

iMac with AMD RADEON 560 (Part No. MNDY2xx/A) iMac with AMD RADEON 580 (Part No. MNED2xx/A) MacBook Pro 13 inch (MacBookPro13,2) Macbook Pro 13 inch (MacbookPro14,2) In the moment we do not have access to an iMac Pro or Mac Pro. We can test those either with Team Viewer access or by getting them into the office and integrating them into our build system. We will not test any Hackintosh configuration.

We would send this bug to apple for their driver development team ... please note we do not test on Mac Pro ... at the moment we do not have a Mac Pro in the office.

Hi,

I did some debugging an found out that the problem is due to missing fnma support of my processor intel xeon x5650.

What I did: I've written a simple main program like this:

int main(void) { const uint32_t gNumAsteroids = 50000U; // 50000 is optimal. const uint32_t gTextureCount = 10; const uint32_t gImageCount = 3; uint32_t numVerticesPerMesh = 858;

AsteroidSimulation gAsteroidSim; gAsteroidSim.numLODs = 3; gAsteroidSim.Init(123, gNumAsteroids, 1000, numVerticesPerMesh, gTextureCount); return 0; }

I reduced the AsteroidSimulation::Init method to simply 2 statements:

void AsteroidSimulation::Init(uint32_t rngSeed, uint32_t numAsteroids, uint32_t numMeshes, uint32_t vertexCountPerMesh, uint32_t textureCount) { std::cout << numAsteroids << "\n"; float xxx = 1.0; }

Now if compile this code by

g++ -I. -g -std=c++11 main.cpp AsteroidSim.cpp

I get:

AsteroidSim.cpp:238:5: error: always_inline function '_mm_fmadd_ps' requires target feature 'fma', but would be inlined into function 'update' that is compiled without support for 'fma'

Then I compile with -mfma: g++ -I. -g -std=c++11 -mfma main.cpp AsteroidSim.cpp

Compilation is successful, but the program crashes in AsteroidSimulation::Init with EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)

It means my processor has no fnma support. I can check with sysctl -n hw.optional.fma

The result is 0, indicating missing fnma support.

My question: Is fnma support absolutely necessary or are there any compiler-flags or defines which allow execution on non fnma supported CPUs?

Best regards

Problem solved!

I was playing a little bit more with the code and was able to compile and run 04_ExecuteInDirect on my MacPro 5.1

First: In AsteoridSim.cpp, line 176 I added a defined(NO_FMA): ...

if defined(_DURANGO) || defined(TARGET_IOS) || defined(NO_FMA)

// XBoxOne/iOS don't support some of these SSE instructions. // 0xC000001D: Illegal Instruction // Implement it without SSE

dynamicAsteroid.transform = orbit dynamicAsteroid.transform rotate;

else

...

Second: For AsteoridSim.cpp I removed the compilation flags -mavx2 -mfma and replaced it with -DNO_FMA

That's all! Now 04_ExecuteInDirect is nicely on my MacPro 5.1 using the graphics power of my AMD Vega RX 56

Can you add something like like this (NO_FMA) to support CPU's without vx2 or fma support?

Best regards

Another (better) solution:

The problem on my machine (MacPro 5.1, 12 core, Westmere) was caused by the _mm_fmadd_ps instructions which are only available if your CPU supports fma instructions. Unfortunately these are not available on Westmere processors of the MacPro 5.1. However you can replace _mm_fmadd_ps(a, b, c) by _mm_add_ps(_mm_mul_ps(a, b), c). It will probably not make a big difference in terms of performance.

The code below shows the modification in AsteoridSim.cpp:

In line 220, instead of intermediateSSE[i] =_mm_fmadd_ps(orbitSSE[0], vx, _mm_fmadd_ps(orbitSSE[1], vy, _mm_fmadd_ps(orbitSSE[2], vz, _mm_mul_ps(orbitSSE[3], vw))));

you can replace the _mm_fmad_ps(.. by _mm_add_ps(_mm_mul_ps.. The modified statement looks like this:

intermediateSSE[i] = _mm_add_ps(_mm_mul_ps(orbitSSE[0], vx), _mm_add_ps(_mm_mul_ps(orbitSSE[1], vy), _mm_add_ps(_mm_mul_ps(orbitSSE[2], vz), _mm_mul_ps(orbitSSE[3], vw))));

and analogeously a few lines below:

transformSSE[i] = _mm_add_ps(_mm_mul_ps(intermediateSSE[0], vx), _mm_add_ps(_mm_mul_ps(intermediateSSE[1], vy), _mm_add_ps(_mm_mul_ps(intermediateSSE[2], vz), _mm_mul_ps(intermediateSSE[3], vw))));

Then you have to remove the -mfma -mavx2 compilation flags for AsteoridSim.cpp

Best regards

That is super awesome! Thanks for providing this fix. We will add it.

[wolfgangfengel]

Should be resolved. Let us know!
