Debug gpu_utils.py - unique temporary files for parallel execution #325

Closed kpoeppel closed 7 months ago

kpoeppel commented 11 months ago

When keops are used in parallel runs (e.g. when sweeping), the temporary file created in gpu_utils.py did have the same name leading to a race condition on the file system and FileNotFoundErrors. This PR fixes this by creating unique temporary files using the Python standard library. Fixes #324
