Your CPU is an Intel Core i7-10810U with 6 cores and 12 threads. Each core has 2 threads (hyperthreading is enabled), and you have 12 logical processors (CPU(s)).

You have 24GB of RAM available, which is more than sufficient for the recommendation of 2GB per core. With 6 cores, the recommendation would be 12GB, and you have double that, meaning you should have no issues with memory during the O2Physics compilation process.

You can compile with multiple jobs using the -j option for make. For example, you could use all 12 threads like this or more conservative only 6.
