Return to Mandelbrot sets using a Supercomputer! – the Nvidia DGX-1

Monday, December 16th, 2019

Put on that paisley shirt, play some Sgt Peppers, and lets explore Mandelbrot sets again….

Picture yourself in a goat on a river, With tanberine trees and marmalade skies

Five years have past since I last wrote about Mandelbrot sets, when I use two Nvidia Tesla K40s to generate the Mandelbrot set.

Both those GPUs had only 2,880 compute cores each, a total of 5,760, The Tesla V100 in the Nvidia DGX-1 has 5,120 cores per GPU, and there are 8 GPU, so a total of 40,960 cores.

Here is a video comparing 1 x CPU on the left and 8xGPUs on the right! The same Mandelbrot regions are explored in real time, left and right. The CPU is running at 5fps(150ms), and the GPUs at 50fps (3ms)

The Roundabout, for Andy “The Return to the Mandelbrot sets!”

Thursday, February 20th, 2014

When I first started experimenting with computers in the early 80’s, I was fascinated with the Mandelbrot set, and spent many hours generating it on a BBC Micro, later I added a Second 6502 Processor, I then upgrade to a Master 128k with a Turbo Co-Processor, all in the aid of more compute power! (I search high and low for a Acornsoft GXR rom, to give me more colours, and finally got one from Plymouth Polytechnic Computer Science Department!).

BBC Micro Mandelbrot

This week, I find myself with the following configuration:-

  • (2) nVidia Tesla K40 (currently the most powerful and most expensive graphics processing unit (gpu), used for compute (no video output!).
  • 1 Terra Byte PCI-e Flash Card (SSD but plugs into the motherboard!).

This is a real time, video of calculating Mandelbrot set, using CUDA 5.5 on the 2 nVidia Tesla K40, a little faster than using a BBC Microcomputer!

New Desktop Computer Part IV:- Complete – 7 TFLOPS

Tuesday, December 18th, 2012

it’s been a long and difficult birth for this PC, lots of testing and unknowns, to get this created, but here it is:-
andysnewpc12

So what does this computer do, well at idle it consumes approx 200 watts (measured) of electricity, at full load, it uses approx 850 watts (measured) of electricity  to drive an Intel Core i7 990X Extreme Edition processor, and two nVidia SLI GTX 590 3GB DDR5 RAM, that’s a total of 4 GPUs, and the machine’s number crunching performance is approx 7 TFLOPS. (GPU+CPU combined)  The GTX 590 were one of the worlds fastest graphics cards, recently surpassed by the nVidia GTX 690.

Yes, this rig runs very hot, and may need to be water cooled at a later date, or change of case and fans, or radiator based cooling for the CPU, still under testing and development……work in progress!

DVD Decrypter beaten!

Wednesday, June 23rd, 2010

I’ve been using DVD Decrypter to rip and backup my DVDs to iPods for years, despite no further developement since 2005.

DVD Decrypter Version 3.5.4.0 (final)

DVD Decrypter Version 3.5.4.0 (final)

An exceptional tiny application that easily removes the Copy Protection System from DVDs, which enables you to transcode the DVD for mobile device playback. I also use Badaboom, Badaboom is a blazingly fast media converter that formats video files for a variety of devices, including iPod, PSP, iPad, and YouTube, by using your system’s graphics processing unit (GPU).  If you have an Nvidia chipset!

So I was a little surprised when I couldn’t backup Disney’s new Alice In Wonderland…

It starts to report Read Errors (Retry 1 etc), but this DVD disc is brand new out of the cellphone wrapping, so it cannot be physical errors on the media, but something is odd, because if you look at the number of files and total it’s repoting 58GB on the disc, this should read alarm bells.

if you continue, the Retry errors increase and eventually, you’ll get an error message below

if you ignore this error message, it will continue to extract the data, but you’ll end up with a 58GB DVD! It would appear that Disney have done something with the layout to confuse DVD Decrypter Version 3.5.4.0 (final). Maybe it’s the Fast-Play, I don’t know, but as I’ve always said software can always be broken with software, so time to try another software product…

Enter DVDFab HD Decrypter, another backup tool which is also FREE.

Ah, this software does the job nicely, shame I still prefer the simplicity of DVD Decrypter, and it’s has a tiny footprint.

So if DVD Decrypter doesn’t work for you try DVDFab HD Decrypter
