Seems like it has about 700/5 = 140 GPUs. And they are about 0.4kW each. Let's say it is 50% utilized for a year. That is 140 * 0.4 * 0.5 * 365 * 24 = 245280 kW

Seems like it has about 700/5 = 140 GPUs. And they are about 0.4kW each. Let's say it is 50% utilized for a year. That is 140 * 0.4 * 0.5 * 365 * 24 = 245280 kWh.
Let's say electricity generation creates 0.5 kg CO2e per kWh. So 122640 kg CO2e per year.
For comparison, driving a cars creates about 0.2kg CO2 per km. Or 0.32 kg per mile. So about the same as driving 122640 / 0.32 = 383250 miles per year. Call it 38 cars.
Edit: Corrected the above CO2 per km figure to fix a factor of 100 error.
Obviously there are a million things wrong with this analysis. For example, we don't know if they're going to use the machine to do climate modelling that will lead to a headline in the media that causes the green party to be elected ;-)
- lorenzhs 6y agoHPC system utilization is typically upwards of 90%, these things are not idle. There's almost always a queue of jobs waiting to run, at least in my experience.
- rubatuga 6y agoDefinitely, also it makes you hate those who hog up the resources. A good scheduler will take into account the past usage however.
- jcims 6y agoCars generate closer to 122g of CO2 per km [1]. 122,000kg would be ~1 million km or ~50 cars. 1 - https://ec.europa.eu/clima/policies/transport/vehicles/cars_en https://ec.europa.eu/clima/policies/transport/vehicles/cars_...
- abainbridge 6y agoDamn. I was confused by the fuel consumption being in per 100 km units. I've edited my post. Thanks.
- jabl 6y agoIt has 140 nodes, each with 8 GPU's. Add in extra infra like storage, networking etc. and you're looking at around 700 kW at 100% utilization.
- abainbridge 6y agoYou're right. The article is wrong. It said: > A single A100 GPU’s 54 billion transistors can execute 5 petaflops of performance, according to Nvidia. It is a single system of 8 GPUs that can do 5 petaflops. I can't edit my post anymore. Multiply my numbers by 8, or a bit more if you want to take into account higher utilization and the other overheads you mention. So ~500 cars. This is my final offer.
