Project Radium Preview

A brief discussion of the newly released demo video of Project Radium.

I can't miss the days of radio, because my birth missed them first. Nevertheless, in my youth, after TV, laying in bed, I tuned in to Radio Mystery Theater on the AM dial and listened to spooky dramas, in the dark, just before going to sleep. Radio relies on conspicuous sound effects and exposition, but your imagination lands you just as solidly in the thick of trouble, tears, and triumph as any movie. Radio became a preview for television.

Message from Little Orphan Annie Decoder Ring, "Be Sure to Preview Radium Demo". Ovaltine Upset.

Today you can see our first preview of Project Radium in a demo with expository slides, expository narration, and gripping action sequences of time-lapse text scrolling up.

Radio Days as depicted in The King's Speech

Movies with families gathered around the radio, such as The King's Speech, indicate multi-tasking has a long history and that intelligence was not always artificial.

In my earlier Project Radium blog, I explained that like Bitfusion, Project Radium virtualizes GPU devices. Some key points were:

  • The CLI look-and-feel will be much like Bitfusion.
  • The implementation is from the ground up and uses different technology than Bitfusion.
  • Its general-purpose approach supports multiple devices & device types, and multiple vendors.

The new Project Radium demo shows its functionality (early performance of Project Radium is discussed here). The demo uses three machines on three separate hosts. One host has no devices, one host has a couple NVIDIA V100 GPUs and one host has an AMD MI100 GPU. The "deviceless" host runs commands and applications and we see the following:

  • Radium finds and lists the remote GPUs.
  • Radium migrates a process (with lots of print commands) from one machine to another and back again.
  • Radium runs a TensorFlow app using a remote V100 GPU.
  • Radium runs a TensorFlow app using a remote MI100 GPU.

Graphics like those in Figure 1. explain all the pieces in play, and simplify the programs and commands with a few lines of pseudo code. The CLI capture shows not only the running applications, but also monitors the remote GPUs so you can see when their memory and cores are being used.

If you are interested in Project Radium, the demo is only five and a half minutes and well-worth a watch. A big Project Radium goal was multi-vendor support. It is particularly satisfying to see virtualization working for both NVIDIA GPUs and AMD GPUs.

And Now for Something Completely Radio

Years ago I ran across a used book of radio scripts from the Goon Show. I'd never heard of it. Turns out it was something of a preview or inspiration for Monty Python's Flying Circus, the TV show. My children and I started performing the scripts for ourselves at bedtime, laughing ourselves silly for 30 minutes or so. Later, when we came across Goon Show audio recordings, we were surprised to hear that our voicing of various characters approximated those of Peter Sellers and Spike Milligan.  If you'd like to perform one yourself, complete with sound effects, try this version of the episode called The Dreaded Batter Pudding Hurler (of Bexhill on Sea).
