Igor,

Thank you for responding.
Your response raised a couple of further questions. I know you are currently quite busy, so I try to be as brief as possible.

When you say:
But to analyze more, your hosts in particular use the 10 GF mark.

Is it somehow related to this:
3) clever people implement Anonymous Platform with an artificially high performance value assigned. A slow platform will get dis-proportionally more credits, because the credit is calculated as time * platform_performance.


You say:
Therefore, when you deliver the canonical result in the run-time credits calculation your credits soar. Like this you did get a large credit from your work already and there was no need to upgrade.

I'm not a native English speaker, so I'm reading this in two possible ways:

1) When one of my hosts report a WU and it's validated, the credits awarded for that WU are already large.
For example that long WU validated from my first message:
http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=2490815
It had 155.83 credits awarded, so that is already large enough.

2)When one of my hosts report a WU and it's validated, the credits awarded for that WU are multiplied by a host specific number and so are already larger than is indicated.
The same example:
http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=2490815
It had 155.83 credits awarded, but in reality I have already been given more than that.

Which is correct?

I decided to investigate some more.

I looked at Free-DC's "LHC@Home 1.0 Users Stats" and saw that the "Last Update" column had credits awarded after the regular daily update. I assume that currently (when I write this) it indicates the additionally awarded credit.

I'm going to amuse all of you who have written to this thread by showing your and my "Last 28 Days" and "Last Update" credits shown by Free-DC (I hope you don't mind):

Sunny129: _ _ _ _ _ 94595_ _ 22877
Michael Karlinsky:_ 18932_ _ 3716
tullio: _ _ _ _ _ _ 3356 _ _ 2493
Igor Zacharov:_ _ _ 2385 _ _ 347
Petri S:_ _ _ _ _ _ 154342 _ 201

Have I won the lottery? ;)

If I recall correctly, all of my three active computers had long WUs.
http://lhcathomeclassic.cern.ch/sixtrack/show_host_detail.php?hostid=9964580
http://lhcathomeclassic.cern.ch/sixtrack/show_host_detail.php?hostid=9960841
http://lhcathomeclassic.cern.ch/sixtrack/show_host_detail.php?hostid=9973599

The awarded points were apalling, but i can currently see only one as validated:
http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=2490815

There seems to be two WUs waiting for validation:
http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=2536373
http://lhcathomeclassic.cern.ch/sixtrack/workunit.php?wuid=2536459

I'm pretty sure there were more, because I was worried those WUs might not complete in time, but all eventually did.

Compared to many of my countrymen, who have suddenly gotten huge amouts of points, I've only had an average amount. So it's possible I might be missing some points.
