RE: Towards a citizen science particle physics research project on Hive

Ok, I'm interested.

If I remember correctly from your previous post the software mainly uses CPU to compute (and not the GPU via CUDA), for one simulation it uses 100% of the CPU? Multithreading? how long does it take usually to perform one simulation (computer side)? For the storage, does it needs to be on SSD?

It is really great that we are able to count you in (as said in the reply to your comment to my post in French of last week).

In terms of resources, all codes that we will use run on standard CPUs. Multithreading is definitely a plus (4 cores would be comfortable, 8 or 16 very pleasant). Having however only 1 core is not blocking. This just requires more coffee to fill the time that is necessary for the calculations to be done.

Relative to storage, having an SSD or HDD drive does not really matter, as long as space is available. 100 GB is probably a minimum. The real bottleneck (which is not a bottleneck, in fact) is that large intermediate files will have to be used. They are however intermediate, which means temporary. As soon as they are produced, we will run a reconstruction algorithm to make them small. Please don't ask me for details, this is the topic of the post of next week ;)

Cheers!
