An idea for a very simple validation option, that does not require the validator task :

If a project needs exact validation without the need to accept a few % floating point inaccuracy, it would be possible to work without a separate validator task.

If simple validation is configured, the core client could build CRC32 over all upload files that belong to a workunit and xor the checksums of all files into only one 32bit int value.

Those checksums could easily be compared by one of the other tasks (Transitioner?) without the need of an extra validator program.

For projects who don't need any validation, there is sample_trivial_validator which always says "yes it's valid" without even looking at the result.

Getting rid of the validator task completely would need changes in other programs. If no program marks the workunit as validated, it never continues flowing through the BOINC system.
