Got my first S5 unit today. Should I replace akosf's (thanks dude!)albert_4.37_windows_intelx86.exe with the original before the new S5 unit starts processing?

not necessary - the S5R1 App will be a new file.

Cool. Thanks BM!

Just to help you all keep

Just to help you all keep track of things I had this happen today on one box.

Shortly after that I had this happen as well on the same box.

However these WUs are still in the queue to be processed. Don't know what's going to happen when that time comes. Should get to them in the next day or two.

Im also getting all my downloads failing. Im running truxoft-ccc with u41.05 app. It also failed to doenload the new application. All S4 work units are downloading fine so not a conncection problem.

Some hours ago we had some problems with at least one download mirror, which should, however, be solved by now. The problem may have been on our end.

I restarted boincmanager

I restarted boincmanager using file-exit and got the following errors on a pair of new s5 WUs when I restarted. I'm using the boinc studio versions of boinc/boincmanager so it might be from that, not the science app.

I think you better reset the project - the error messages from your S5R1 results look like the files have been corrupted and your client apparently didn't try to get them again.

One think I'm curious about

One think I'm curious about is checkpoint frequency. With the general increase in completion times, will results in progress be checkpointed often enough to avoid large losses when the application (and BOINC client) is stopped and restarted?

Oh, and personal opinion only - standardized credit = good; longer completion times = not so good. Completing 8 "work units" in 16 hours just "feels better" than completing 2 work units in 16 hours, credit issues aside. Of course, that's purely subjective and mostly irrelevant.

The intention is that the average Einstein@Home participant will get the same credit per hour "work" than what he gets on other BOINC projects.

I respect that this is what the project should do.

It does, however, mean that those of us who have been enjoying a credit feast with the akosf S4 aps will see our credit production per hour nosedive with S5 (since we have been getting far higher than BOINC-standard credit per hour).

Personally, I think this is just fine. Akosf's aps provided a wonderful speedup. Those of us who adopted them early constituted an extremely large-scale "beta test" which was arguably useful to him and to the project in validating that the science results were useful and did not come hitched to high data-dependent application fault rates of one kind or another. We got a temporary adventurer's reward of credit, but as the more efficient techniques are folded into the project it is back to parity. Should yet further independent improvements arise, it seems likely your current credit scheme would again allow them a decent interval of extra credit/hour reflecting their higher science/hour.

@Bernd, you were asking about the controversy about SETI@home Enhanced: AFAICT it was mostly generated by people expressing an attitude diametrically opposed to archae86’s here, mutus mutandis.

The checkpointing frequency is determined by the "write to disk at most every" setting in your general preferences. There is a limit in the App, of course, but I doubt that this is above the 60s default even on slow machines. The times between checkpoints is the maximum time that gets lost when the App is interrupted, plus a few seconds it takes to read and process the checkpointed state when resuming.

I’m already getting a “no work from project� message on a system running the beta Mac/PPC v4.56. Should I delete the app_info file immediately, or will S4 work (replacing lost or erroneous results) still be available for a while?
