Sorry to ask what is probably a silly question but is it normal to have (currently) as many as 84 tasks awaiting validation? With my validated items I have over 200k credits now and just wondering why so many of the completed tasks are still awaiting validation.

Many thanks in advance.

My response is "Only 84?".
It is quite normal to have to wait days for a result to be validated. If you care to look at my three current crunchers you will see that I have well over a thousand awaiting validation.

The answer as to why it takes time, is that tasks are sent out to two computers initially. Both computers will have to upload & report the result before a first validation round takes place.

If there's a problem spotted, a third task goes out to a third computer. When that one has returned the result, a new round of validation takes place. If there's still a problem found, a new task is sent out to a fourth computer, and so on until either a canonical result is found and (most) everyone gets validated correctly, gets credit etc.

When you check the details of a task's outcome, you see what the minimum quorum is (the amount of tasks needed for a canonical result), the initial replication (the amount of tasks sent out initially), and the maximum number of error/total/success tasks.

Add to that that all computers are different, that depending on cache size, speed of the CPU, amount of cores used, speed of the GPU, amount of GPUs in a system, amount of time the computer is allowed on, amount of time BOINC is allowed to run during the previous time, etc. etc. etc. and you can see that it can take quite a while before a canonical result is reached, validation happens and credit is given out. Months, really.
