Fixed by removing /arch:AVX
from the SConstruct file.
I suppose this flag should be removed, for better hardware compatibility.
Is there a feature in TOVE that requires AVX support?
@pdesaulniers No, AVX just makes some things considerably faster (esp. the dithering stuff in fact, where lots of pixel data is moved around). However, I haven't benchmarked this, so removing /arch:AVX
is a good idea. I'll take care of it.
Actually, I'm getting the same error (SIGILL) on my low-end Linux laptop.
In this case, the fix was to remove the -mf16c
flag, and to tweak common.h
so that store_gpu_float
uses the non-instrinsic fp16 conversion.
Ok, thanks a lot for debugging this. I'll change the defaults to not use this.
If I run the blob demo on Windows, using the latest v2.0a3 release, I get an
Illegal instruction
error.I also get this error in the latest git version, built using VS Community 2017.
I'm running Windows 10, 64-bit.
The v2.0a2 release does not have this issue.
