Limits

So is this 100 WU limit per a computer or per an account?

Per computer, plus another 100 if it has at least one usable GPU.

So currently the most I'd be able to get is 100 WUs for the CPU and 100 WUs for GPUs regardless of the number of GPUs in the computer?

Yes, but note that it's a limit on tasks in progress. If you report 5 completions, you can get 5 new tasks to replace them. Most of the highly productive hosts are in that mode. It's not fair that the limits are really only affecting the top 8000 or so hosts, of course.

Even though they may carry a huge cache, at least they return the work within the period thier cache is set for. Whereas there would be 1,000s of systems out there tht take almost to the deadline to return their work (if they do return it).
I'd expect they'd have a significant effect on the size of the database too.

If the limits are still on, how come this happens.

Dunno, but I wish I could get it to happen here.

Well one interesting side effect of the 100 unit limit per device on MB is that it makes it relatively simple to calculate your process rate, assuming your rig is set to run 24/7.

Simply subtract the Time Reported from the Time Sent on valid tasks for a particular device (cpu or gpu), you may want to average several to help compensate for the 5 minute minimum delay between reports, and divide by 100.

For my little rig it ends up being around 1 CPU unit done about every 56 minutes and 1 GPU unit (done by the integrated GPU) about every 45 minutes. So about 57-58 units a day. SIV is giving me, based on average number of fetched units per day over the last 6 months of 61. So pretty spot on.

You can also use this to get a guestimate on how many CPU and GPU threads are running on other people's hosts. Of course this assumes they are running 24/7 and just Seti and primarily MB vs AP but you can get a ballpark figure.

Looking at the most productive host out there, owned by Morton Ross. Using the average time between report and sent of the first five, 100+ credit GPU units, I calculate a GPU unit completed every 32.3 seconds. Task details show 8 GPUs in the system. The average run time of those first five is about 781 seconds which yields a guesstimate of 24-25 GPU threads running across those 8 GPUs.

On the CPU side is a little tougher to compute since valid CPU units are less regular in the valid list but after finding five I calculate one CPU unit done every 517 seconds with the average run time of 6946 seconds gives me a guesstimate of 13-14 threads running CPU units. I'll say that the remaining available threads are handling the CPU overhead of the all the GPU threads.

It's just a curious bit of math, still dependent on a lot of assumptions. Still one GPU unit every 32.3 seconds is a bit of a jaw dropper. It's no wonder that one host handles about one out of every 650 units.
