Render Buddha fractal on decommissioned P106-90

Probably I got an answer, how to prepare me to parallel data computing with great Pascal architecture for my small budget 30usd. I have found Zotac P106-90 is out of mining game for now, I can bought and adopt for GPU computation. This graphics card looks like Zotac GTX 1060 but it have no any video output. My first test is for Windows 10, latest Cuda 10.2 produce great Buddha fractal for me. For render Buddha 48MB fractal image it takes 6 min.

nvcc --version

I used JCudaFractals written in Java with JCuda library.

mvn compile
mvn exec:java -Dexec.mainClass="net.marvk.jcudafractals.Main"

Sometime I got CUDA_ERROR_ILLEGAL_ADDRESS errors.

In common this cheap GPU works in calculations as expected.

I also check performance parameters in CUDA-Z program that show, it is slow to upload data to device, but it very fast to share data between several devices.

Two AppImage for a day

I have found large Linux applications have packed for AppImages I can run without install.

The AppImage format is a format for packaging applications in a way that allows them to run on a variety of different target systems (base operating systems, distributions) without further modification.

 First of them is Gravit Designer that can open and edi Adobe Illustrator files, looks like important thing.

Second, is decade known for me program, Scilab. It works now pretty fast when I know it teen years ago.

To download AppImage for Scilab, base on the answer:

mkdir ~/Software
cd ~/Software
wget https://github.com/davidcl/Scilab.AppDir/releases/download/6.0.2-1/Scilab-x86_64.AppImage
chmod +x Scilab-x86_64.AppImage
ln -s Scilab-x86_64.AppImage scilab
