This repository contains the source code for Development of Linux Block I/O Accelerators (DeLiBA) which is being developed at ESA group. DeLiBA lifts key functionality of Linux block I/O layer up into userspace, enabling the use of a wide spectrum of programming tools. For an initial proof-of-concept DeLiBA in current state uses Ceph based libraries. And to accelerate the Linux block I/O stack computations, it currently uses FPGA-based based hardware accelerators.

Note Still missing some upstreams. Going to push in next days.

The source directory has the following repository structure:

.
├── nbd                    # network block device libraries
├── ceph                   # selective Ceph libraries as indicated in DeLiBA publication
├── fpga                   # task-based APIs to launch requests from host software on FPGA

Following profiling and benchmark tools have been used during our work on this framework:

• Intel VTune
• Valgrind
• fio

Any contributions you make are greatly appreciated. Simply open a pull request, or open an issue.
