where `<ranks>` is the total number of GPU's to use. On Tursa this is 4 times the number of nodes.
Note: on Tursa, the `wrapper.sh` script that is typically used with Grid is not necessary.
Note:
- on Tursa, the `wrapper.sh` script that is typically used with Grid is not necessary.
- due to Qudas automatic tuning, the benchmark might take significantly longer to run than `Benchmark_Grid` (even though it does fewer things).
- setting `QUDA_ENABLE_TUNING=0` disables all tuning (degrades performance severely). By default, it is turned on.
- setting `QUDA_RESOURCE_PATH=<some folder>` enables Quda to save and reuse optimal tuning parameters, making repeated runs much faster
