This is due on April 20th, but I would prefer it on the 19th if possible.
Hiding Network latency when performing remote file access. A standard technice for hidning network latency and increase the throughput of remote file access is prefetching, ie. issuing I/O operations before the time the data is actually needed. Prefetching can be performed either by the application , e.g., using a non-blocking file access API, or by the file system client, when the latter detects that the application is access a file sequentially.
In this problem you are asked to demonstrate the benefits of application-driven file prefetching by writing a sample application that performs random reads from a set of small (e.g. 32KB) files over NFS using non-blocking I/O API. Each read I/O should read a file in its entirety.
