 | Log-based	| 514 |	LOG	| The log-based VOL plugin stores HDF5 datasets in a log-based storage layout.<br>In this layout, data of multiple write requests made by an MPI process are appended one after another in the file. Such I/O strategy can avoid the expensive inter-process communication and I/O serialization due to file lock contentions when storing data in the canonical order. Through the log-based VOL, existing HDF5 programs can achieve a better parallel write performance with minimal changes to their codes. | [https://github.com/DataLib-ECP/vol-log-based/blob/master/README.md](https://github.com/DataLib-ECP/vol-log-based/blob/master/README.md)	| Kai Yuan Hou <br> (khl7265 at ece dot northwestern dot edu) |
