Scallion hangs after Looks good about scallion HOT 8 CLOSED

Hmm... have not seen that issue. Which version did you download? We recently released version 2.0 which has some major changes. You can try checking out https://github.com/lachesis/scallion/tree/master (the old version) and see if that works better for you.

Also, what device are you using GPU, CPU, etc (be specific)? You can list devices with "scallion.exe -l"

from scallion.

My apologies for the late reply and thanks for looking into this. I was using version 1.2 and I cloned the git (that was 2.0 I guess).

I used an Amazon GPU instance (g2.2xlarge) with the AMI: Ubuntu-12.04_GPU_CUDA-OpenCL-PyOpenCL (ami-87377cee)

This is what I first did, the prebuilt version:
wget https://github.com/lachesis/scallion/blob/binaries/scallion-v1.2.zip?raw=true
mv scallion-v1.2.zip?raw=true scallion.zip
sudo apt-get install mono-complete unzip
unzip scallion.zip
cd ./scallion-v1.2/
screen
mono scallion.exe -l

After that I tried building from source:
sudo apt-get install mono-complete git-core
git clone https://github.com/lachesis/scallion
cd ./scallion/
xbuild scallion.sln
cd ./scallion/bin/Debug/
mono scallion.exe -l

Both times this was the output:
Id:0 Name:GRID K520
PreferredGroupSizeMultiple:32 ComputeUnits:8 ClockFrequency:797
MaxConstantBufferSize:65536 MaxConstantArgs:9 MaxMemAllocSize:1073692672

If I am the only user with this issue, it might be a problem with the setup I tried and not with the program itself. Anyway, thanks for replying.

@bartbroere I have not setup scallion on AWS before but others have so I would guess its a configuration issue. Someone was going to make a AMI image with scallion preconfigured. Let me send them an email.

@bartbroere AMI image coming soon! :) more info can be found at https://www.nikcub.com/posts/securing-blockchain-users-with-tor-and-ssl/

Thanks a lot! I will definitely watch that website.

Is there any update on this? My scallion locks up after a few moments..

From there it just hangs.

I make it works today, using also ami-87377cee. I think your problem came from the mono version from Ubuntu repositories. It is incompatible with scallion (it hangs/crash/...), you must use the last stable with:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
echo "deb http://download.mono-project.com/repo/debian wheezy main" | sudo tee /etc/apt/sources.list.d/mono-xamarin.list
apt-get update

then if you already had mono installed:

apt-get upgrade

else install it with:

apt-get install mono-complete

from scallion.

Awesome, thanks for the workaround. I'm going to close this for now, as this issue is fixed with newer mono.
