Illegal Instruction core dumped

[Toma-Bad]

Hi,
I'm trying to run the AppImage of carta v3.0 on my Ubuntu 18.04 installation, but i get the following error:

/tmp/appimage_extracted_20170caa873dac89d7c4d9bd8a62d6e5/AppRun: line 26: 3215944 Illegal instruction (core dumped) $DIR/bin/carta_backend "$@"
What should i do?

I have transferred this bug report from the backend repo.

@Toma-Bad which AppImage file did you download? Are you sure that it matches your system's architecture?

[Toma-Bad]

Hi! Yes, it was the latest AppImage for the correct linux version.

@Toma-Bad I wonder if the problem is with the AppImage executable part.

Are you able to extract the Appimage by running the following command?

./carta-v3.0-x86_64.AppImage --appimage-extract

If that works, are you then able to run the following?

cd squashfs-root/bin
export LD_LIBRARY_PATH=../lib:$LD_LIBRARY_PATH
./carta_backend

Also, would you be able to share the output of lscpu with us please?

Hi, I extracted and followed the instructions, and the result was this:

@Toma-Bad Thank you for the information. We investigated and I'm sorry to say that CARTA is unable to run on your computer. The carta_backend requires compatibility with the SSE4 instruction set at the very least. Your AMD Phenom 9550 CPU is 15 years old and although lscpu shows that it supports SSE4a, it seems SSE4a was a special AMD implementation that did not contain all standard SSE4 instructions. So that is why the carta_backend immediately crashes. It is probably not the answer that you want, but all we can suggest is to run CARTA on a different computer with a newer CPU.

[Toma-Bad]

Thanks for the reply, I will try to get it installed on the institute system. All the best!

Is this still an issue with v4-stable release? If not, or there are alternative solutions, can we close this issue?

[ajm-ska]

It is still an issue, but there is no solution other than using a modern CPU that supports the full SSE4 instruction set. Current and future carta-backends will require the full SSE4 instruction set to fully utilise the performance available from modern CPUs. We'll be able to close the issue now.
