If we are running with the console runner and several grid nodes does the setting for allowing parallel execution run all the tests absolutely sequentially, using different nodes, or does it run sequentially on each grid node, but in parallel on the different nodes?
If its not the latter is there a way to achieve non parallelisation on a single machine but allow parallel execution across machines (we need non parallel execution due to file system constraints, but each machine has a separate file system, so they could be run in parallel across different machines?
