## 2. Hardware requirements

CPUs | Memory | Disk
1 | min 2GB (16GB recommended) | ~5GB

This machine needs a reasonably recent CPUs and a large amount of memory (min 2GB, recommended 16GB, ~1.5MB per running job). The amount of disk needed depends on the user jobs; HTCondor itself uses very little (5 GB should be enough for HTCondor alone)
