1) Questions and Answers : Macintosh : unable to save work when your system is down (Message 46610)

It should be as simple as exiting BOINC to shut it down, and doing your reboot and then restarting BOINC.

...did your reboot reinstall BOINC or something? (even that should not have lost any work) Are you using an account manager application? Do you crunch for any other projects? And if so, was their work lost as well?

I occassionally run a system clean, and sometimes erase free space. i have noticed that Rosetta work unites are lost when I do this. It would seem rosetta data appear to my computer as FREE SPACE. I'm protected by Intego anit virus and firewall, thousands of attacks are indicated by the monitors, no successful attack has ever been found.
Recently I found that rosetta was stuck on a work unit. So I reset the project to get started again the other existing work to do units are lost. Then as your system was down I reloaded BOINC just incase my copy was corrupted

How can I save work done when your system is down, it is necessary occassionally to carry out maintenance on a computer this usually requires a restart. This was necessary during your recent problems, unfortunately all completed work was lost.

It looks like you are getting twice the number of jobs (8 six hour jobs per day) for which you get half the credit of comparable machines.

Look at this host. It has the same specs and gets about 100 credits per 6 hour job (might be slightly overclocked).


I'm not following. For the 27th, I returned 7 jobs (I was just finishing transitioning from 8 to 6 hour jobs). I looked at the machine you referenced. It had 8 jobs on the 27th too. Seems to me they pretty much mach with regard to number of jobs.

Besides the difference in credits, I am seeing no other difference....except for the OS of course.

I checked the processes. There are only the two rosetta application running, each at about 100%, which is right for a dual core processor. For what it's worth, it looks identical to the ps output from the Pentium D machines.

Try to set this host to a new venue, let's say "school" and set number of processors to use to 1 so that only one instance is running. Then let it crunch 24 hours and see how much credit you receive for 6hour WU. I'm sure we will narrow this down in the end.

The work claimed versus work granted must always be a disincentive for MAC users, also the variation in the percentage granted causes concern in either the way the percentage is calculated or in the way work is distributed or in the way MAC's are utilised.

I think you should be fine with either BOINC version.

Rosetta implemented a new credit system in that timeframe. And what has come up is that on a Mac, the benchmarks run very quickly, and so they presume the machine will crunch well, and yet Rosetta doesn't run as fast as predicted by the benchmark. The new credit system grants credit for the number of models you've crunched. And since the Rosetta models don't compute on par with the BOINC benchmarks, you see a disparity between your claimed credit and your granted credit.

Just this week they added a mention on the site that says:

Note: the Mac OS X (PPC) application is not optimized and will not fully utilize the PPC processor.


"PPC" means Power PC.


Is it not possible for a MAC to run multiple tasks in parallel to fully utilize the bench mark speed.

Surely there must be some MAC Rosetta crunchers who are capable of optimising the PPC applications. It seems wasteful for MAC's to be only computing at 1/3 to 1/2 the performance rates.

I am using a G5 iMac with OS 10.4.7
For most of my time working on Rosetta, submitted credit and granted credit have been the same. For the last month only 50-33% of my submitted credit has been granted.
2. Rosetta recommend BOINC 5.2.5 for Macs.
Boinc recommend 5.4.9 the version I'm using, who is right?

Post:
What is the difference between 'Work done' and 'Average work done'?


The Recent Average Credit (RAC) (shown as "avg. credit" on the projects tab) is sorta like the speedometer on your car. It is the rate at which you go the distance. The "Total credit" is like the odometer, showing the total number of miles ever driven.

Since credits aren't as immediate as the speed reading on a car... the method of calculating it is a bit involved. Since you might be off the net for several days and report a pile of results all at once, they take a longer average over time to figure the RAC so you see a pretty steady number there, in spite of day to day variences.

There is a detailed discussion of it in the Wiki here.

Welcome! Keep crunchin' Rosetta!

I personally imagined it was something like explained, I dont understand why when I was on holiday I had the highest average credit when my computer was off line.

Since the recent server maintenance I am only receiving 50% for work done, is there an error with the server database or is the fault with my computer.

Post:
Since starting Rosetta on my Mac there have been at least 3 occassions when at least 1 day of my submitted results have vanished it would be helpful to know if this fault comes from my Computer the server or elsewhere, Also on one of these data loss occasions a serious disk error resulted on my computer. Fortunately running disk utility about 6 times eventually corrected this error.
