What this GPU network map shows
Each marker is a host record in the current directory: 183 records across 101 cities and 39 country codes. 33 of those records are flagged online. A marker is a location, not a contract. Clicking a country does not reserve a machine.
Online means the record is marked online in this dataset. It does not promise free VRAM, a public IP, or a particular GPU model. The gpu field on these records is a generic label. The card you can actually boot is the one listed on the marketplace, with a live ask and a VRAM figure.
How to rent from a region you see here
Use the map to see that hosts are spread across more than one country, then leave it. Open the marketplace, filter by the GPU name, and read the ask beside the median. If the ask is far under the median, treat it as a short test, not as a week-long training reservation. Stop the pod when the job ends. Billing is per second while the machine is running.
Multi-GPU training still depends on the offer, not on two pins being near each other. NVLink and InfiniBand are properties of a specific node. Check the GPU pages and the price pages before you assume two nearby cities can share a fabric. For SSH after launch, use the connection guide.
Spot markers are hosts flagged as spot in the same file. Spot does not change the deposit address or the token you must send. Fund the account from Add credits only when you are ready to launch, and send the token shown for the chain you selected.
