Implementation

  This brief section shows that Eclipse implementation does not require too many changes to the underlying time-sharing system.

Our current Eclipse/BSD implementation adds approximately 6500 lines of code to FreeBSD version 2.2.8: 2400 lines for the reserv file system and modifications to the proc file system, and 4100 lines for the new schedulers and their integration into the kernel. The kernel size in the GENERIC configuration is 1601351 bytes for FreeBSD and 1639297 bytes for Eclipse/BSD (an increase of only 38 KB).
