Coming soon – Project Contender

UCL’s Centre for Advanced Research Computing (ARC) is this autumn installing various new one-off systems with new, or currently esoteric, accelerator cards, which we are billing as Project Contender. These systems are: 

“mandelbrot” –  
a Graphcore POD16  



You may have heard about this one before as it is already up and running. Graphcore is a British contender in the lucrative machine learning market. Their unusual processors are designed specifically for machine learning workloads and can be easily programmed in Pytorch and TensorFlow.

“zeno” –  
Qualcomm Cloud AI100 


This has Qualcomm GPUs that are particularly designed for the inference stage in machine learning.

“cricket” –  
ARM CPU, Nvidia GPU 

This has a couple of the popular Nvidia A100 GPUs, but the twist is that the host has an ARM architecture Ampere Altra CPU.

“locust” –  
Nvidia Grace-Hopper superchip 


We are very pleased to have been offered a pre-release sample of this machine by Nvidia. Generally, it is like the system above in that it has an ARM CPU, this time from Nvidia, and an Nvidia GPU, the new Hopper, but these are linked by very high-speed interconnect and have unified memory space comprising both the CPU’s and the GPU’s RAM so that data transfer between the two is handled automatically by hardware.

“terrarium” –  
NEC SX Aurora TSUBASA B300-8 

This is somewhat different. It is described as a vector processor. It has a long legacy with one of its predecessors having topped the Top500 at the Earth Simulator Center.

Nvidia BlueField cards 

A couple of these systems also have BlueField cards. These network cards have an integrated ARM architecture Linux computer embedded on the card. The aim is to offload network functions from the CPU to this auxiliary processor or even to work as a supervisor for running virtual machines on the host.  

Nvidia BlueField Networking Platform 


We envisage that these will attract users from across UCL. Perhaps the most common use might be to benchmark your machine learning codes on these against your usual current resources. Other uses would include working on those or other codes to see how the novel systems may be leveraged, or power consumption comparisons.  

Most of these systems have been delivered already and so should be running early next year. So, if you would like access to these systems get in contact soon (from around the end of November 2023) with ARC’s James Legg (j.legg@ucl.ac.uk) giving a brief statement of what you would like to use them for. Please note that these are experimental machines and so are for projects that concern the machines themselves or their software and are not intended for big production runs.
