Thanks, I could tell when my fan spun up when I loaded the page and my browser lagged.
Turbo.js – GPGPU made simple

Re: Turbo.js – GPGPU made simple
#12Does it really do anything on mobile? Anyone got some example results they can share with us, including hardware/OS/software you're running and what kind of speed up was found?
It works on my Note 3, but not on my S7. The N3 results are about 1.5/3.0 for me. Though wildly varying between runs. Edit: It works on my windows PCs (even in a qemu KVM instance using the std vga, but of course the emulated GPU is slower). However, it doesn't seem to like any browser on linux.
With regards to Linux (though Android's Chrome has chrome://flags and chrome://gpu as well, so maybe some of this applies as well):
It didn't work for at first, but I got it to show me the "Ah snap! There was no error compiling the test kernel or running it, but the numbers don't check out." message at least. By changing the deviation var to e.g. 0 in the debugger you can also force it show you the results (JS: 0.56, JS&Turbo.js: 1.74), but I don't know if those results mean anything.
Steps to maybe fix:
Does e.g. glxgears work?
On Chrome, check the following two pages:
chrome://flags/ chrome://settings System -> Use hardware acceleration when available
chrome://gpu/ My graphics hardware is a positively ancient Intel 965GM. (On Windows on a much faster CPU and using Intel HD Graphics 4000, I get JS: 1.28, JS&Turbo.js: 3.82.)

Reading the benchmark script, and the explanation of it at github, I think the deviation is there to account for floating point artifacts. I.e. where JS = 0.01499.. and GPU = 0.01500.., that's fine, but if the numbers (read results from the fractal function) are deviating more, that's an error.
Edit: Actually, "(JS: 0.56, JS&Turbo.js: 1.74)" seems to be a valid result from what I've seen. May just be that the chosen deviation value is an unfortunate edge case.

#14weird: > Ah snap! There was no error compiling the test kernel or running it, but the numbers don't check out. Please report your browser (+ version) and hardware configuration to us, so we can try to fix this. Deviation was 0.673000000262012. Latest Chrome on a macbook air. Looks like at least one other person has had this issue, I'll report my experience as well. https://github.com/turbo/js/issues/1
Yeah, I'm getting this too.

#15Seems cool... but it doesn't work for me!

Same for me. Linux/Chromium or Linux/Firefox

Hi, please report any issues to the repo at http://github.com/turbo/js. The more hardware combo test data I have, the sooner I can debug these faults. If you have any friends with exceptionally weird configs, please get them to test, too :-)
BTW: If you get the "Ah snap" error, there is some diagnostic data in the console. Please include that in any issue report. Cheers.

Please report to http://github.com/turbo/js. I can't track issues on HN.
