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)

Enable 2 Factor Authentication or Multi Factor Authentication TODAY!

Tuesday, October 29th, 2019

This may alarm you, sorry if it does, this is the truth today, as cybercrime is a big threat…

Some free advice to you all, recently a town councillors email was hacked and hijacked for a week! (more on that later!).

But your password is not safe, if you are using passwords on your internet accounts (email, paypal, forums etc) today which are less than 16 characters and do not use a mixture of numbers, special characters, e.g. !”£$%^&*()_+{}:@~<>?abcdefghijklmnopqystuvwxyzABCDEFGHIHJKLMNOPQRSTUVWXYZ1234567890 it’s at risk now of being cracked!

You may currently complain, when using a finance type internet account, e.g. banking online, to login you’ve got to answer various questions to challenge you to get access – this is what we call Two Factor Authentication (2FA) or Multi-Factor Authentication!

Yes, it’s a pain in the arse, but it protects you from cyber crime, and somebody logging into your account.

A password and an email address, or username is not secure, if you are using insecure passwords – update them at least or change over to 2FA or MFA. (you’ll need a Smartphone or tablet).

I now have access to a research supercomputer (it’s called a Nvidia DGX-1) which has 40,960 GPU cores, or 960 Tflops !!!



This is the server, it is rather noisy and loud!

and it’s designed for Deep Learning, and Artificial Intelligence processing Big Data and is used for research, and also image recognition, e.g. facial recognition. It’s taught and then can tell the difference between a cat and a dog!

Processor Upgrade Sunday

Sunday, July 28th, 2019

This has been on my ToDo list for a while to upgrade the processor in my daily driver laptop. The laptop currently has a socketed Intel Core i7-2640M Dual Core 2.8GHz.

Intel Core i7-2640M Dual Core 2.8GHz.

Intel Core i7-2640M Dual Core 2.8GHz.

The only issue is this laptop only activates two memory DIMM slots with the current Dual Core processor so the maximum RAM is 16GB.

Time to upgrade to an Intel Core i7-2960XM Extreme Edition Quad Core 2.7GHz.

Andysworld! comes home!

Thursday, July 25th, 2019

It’s been just a little over 10 years ago that I migrated Andysworld! and all my hosting to the US, with

BUT – 20 days ago, I was left with

  • No hosting.
  • No email for 4 days.

There was no explanation of when it would return. So I’ve voted with my feet, and brought it all back to the UK, where I’ve been hosting with since 2004, in one shape or form, when they acquired PurpleCloud!! (in 2011).

This is strapline – “Professional Web Hosting from Just Host – JustHost”

All I can say is…Just****.com.

So since I’ve  moved it all back, there maybe some teething issues…
