NVIDIA Introduces cuda-checkpoint Utility for CUDA Applications on Linux 🚀
NVIDIA has recently launched a new command-line tool called cuda-checkpoint, specifically designed to enhance the checkpoint and restore functionalities for CUDA applications on Linux. This tool aims to simplify the process of preserving and restoring the state of CUDA applications, offering greater flexibility and reliability for various computational tasks.
Checkpointing: A Game-Changing Feature in CUDA
- Transparent, per-process checkpointing strikes a balance between VM and application-driven checkpointing.
- It is crucial for fault tolerance, task preemption, and cluster scheduling with migration.
- Combining
cuda-checkpointwith CRIU facilitates the checkpointing of complex applications.
Understanding CRIU
- CRIU is an open-source utility that handles the checkpoint and restore of Linux process trees.
- It manages various kernel mode resources but lacks native NVIDIA GPU support.
cuda-checkpointextends CRIU’s capabilities to include CUDA state management.
Exploring cuda-checkpoint
- The utility supports display driver version 550 and above.
- Users can toggle the CUDA state between suspended and running, termed as suspend and resume respectively.
- During suspension, CUDA driver APIs are locked, CUDA work is completed, and GPU resources are released.
Real-life Application: counter
- An example application called
countershowcases the checkpointing process. - It increments GPU memory upon receiving a packet and responds with the updated value.
- Users can build and test this application using
nvccandcuda-checkpointcommands.
Utility Functionality and Future Enhancements
- As of now,
cuda-checkpointis still in active development and supports x64 architecture. - It operates on a single process, lacks support for UVM, IPC memory, GPU migration, and waits for CUDA work to complete before checkpointing.
- Future driver releases are expected to address these limitations seamlessly.
Summing Up the Benefits of cuda-checkpoint
The cuda-checkpoint tool, in collaboration with CRIU, offers transparent per-process checkpointing capabilities for Linux applications. This feature provides users with greater control and reliability in managing CUDA applications. To learn more about this exciting development, check out the official NVIDIA Technical Blog.
