... but time flies!


and a new supercomputer is needed.

 

The making of a Hybrid GPU Cluster (nameless so far)

- a picture story -

 

Starring:

directors and producers
Frithjof Karsch
Edwin Laermann
Olaf Kaczmarek

 

 

 

... some actors
Markus Klappenbach (cluster administrator)
Fabricio Pucci
Mathias Wagner
Thomas Luthe

 

and transformers: big boxes, smaller boxes, empty space and a christmas tree with own electric power supply

The directors and producers had not only the duty to find components  to transform to a GPU-Cluster and to fight for money but additionally to find electric power under very special conditions. But finally the project could get started in a high security area of the university computer center (HRZ).   

The empty compartment gets filled - the empty frames get filled under the watchfull eyes of directors and actors. As it is Christmas time even the little, electrical autonomous christmas tree is watching the making of the GPU-Cluster permanently.

A new actor shows up - hidden behind the still empty racks: Christian Schmidt

The project is realized together with sysGen Gmbh (a supplier for computer engineering) and NVIDIA (a leading producer of GPUs).
The content of a lot of smaller and bigger boxes has to be filled into 15 racks. In the end there will be 400 GPUs with a processing power of 500 Teraflops.

What makes a supercomputer really expensive?

Electricity is a problem you should never underestimate!

One particular feature of the new computer is its comparatively low power consumption. It is 50 times smaller than a system with the same computing capability composed of PCs.

 


Besides the installation of the GPU-Cluster a (little but not unexpensive) problem occurred: The bigger and smaller boxes transformed from full to empty boxes. Only with the help of heavy equipment the problem could be solved in a long, long lasting campaign.

The memory of the cluster

After several weeks of hard work the cluster is now nearly finished.

 

We protect our baby with all means.

We even put the cluster behind bars
and extra doors

- we save electrical power wherever we can-
Mathias Wagner is starting the cluster with pure manpower on January 25 under the watchful eyes of Olaf Kaczmarek.
