Hi Mark,

I beg to differ in part. While I too hope for a [complete] solution to the ghost problems, I can appreciate the poking around going on here.

As some will attest, poking around with things that have little apparent immediate application beyond the obvious is what I do. Some things turn out to be little more than a curiosity, while others later get used as part of some bigger plan.

An example from my end includes that my initial playing with Lunatics 2.2 code years ago, with no intention for further development, ended up with the first consistently validating AKv8 Windows ports (with a huge amount of support from others). Another is that the installer development followed playing around with CPU identification code, which already existed, but I needed more specific information for future reasons... and is yet to be included in installer development (but will be one day).

I believe it's difficult to predict the possible future usefulness (or lack of) for something, and if only for a learning exercise it is still valuable for that in its own right.

There *could be* a means to induce an aborted by user task status, or possibly other marking, iff we know there were ghosts, what the task was called, and can figure out enough detail to bodgey up the client state. I'm not sure if, or how, such a feat might be practical, but my guess is knowing there are ghosts, and their task details might be a reasonable first step.

I am not always right....never have been.
If it's ghosts you want......well, we got a lot of them hanging around here.

Well, it's nice to know my efforts have paid off. I'm only showing one ghost on my rig. Now, if there were only some way to find the ghosts on my wingmen's machines and get them done. I've got some that have been sitting for months, going from one timeout to another.

Hmmm,

HostID = 5199251

  4,927 WU 'In Progress'
  2,671 WU on board
------------------------
  2,256 Ghost Work Units


That's a lot :/ . If things were functioning I'd look at doing a ghostbusters sequence ... Not an option with ~1000 results ready to report though (plus a lot waiting to upload).

I really hope the figures aren't representative of the status quo. Never did like their music. [Also I make that about 660MiB for this one host...]

What happens when you detach & reattach ?
Does seti assign you a new machine number ?
I realize you need to clear existing wu or loose them
so now with the lack of work would be a good time to do it & loose any Ghosts

-[ snip ]-


Agreed, sorry about that Siran d'Vel'nahr, I was in a rush and chose an annoying host. Later on I did re-upload it to a far better hosting service http://www.mediafire.com/?yyy64lh5953d7.

I've mirrored the 2 files for direct download for the interested :)


Thanks JohnDK much appreciated, you mirroring the files will make it easier for those SETIzens that would like to check it out :)

Greetings,

No problem, Ded1o1, I understand that. I relied on my reserve stash of patience waiting for the download. lol ;) Just thought I would let you know that those with less, little or no patience may not wait around for it.

I have the App installed and it found only 1 ghost. Not sure, yet, what is meant by "ghost unit". My interpretation is that it is a WU that has gone through processing and hasn't figured out yet that it is no longer needed and hangs around pestering users. Is that a fair assessment?

.oO(Will it EVER stop raining here???) :(

Keep on BOINCing...! :)

A ghost unit is one that the server tried to send out to you but it never made it to your computer. The server still thinks it got to you so it will show up on your tasks page but not on your BOINC Manager. They usually come in blocks all sent at the same time.

@ ded1o1

1) Add % value for Ghosts e.g.:
HostID = 1234567

    300 WU 'In Progress'
    200 WU on board
------------------------
    100 Ghost Work Units (33%)


2) Suggestion - put the proper (new) link in your signature:
http://setiathome.berkeley.edu/edit_forum_preferences_form.php

(so people who read only the first post do not use the old link)

e.g.:
_____________
Download GhostDet from this link:
http://www.mediafire.com/?yyy64lh5953d7

@ msattler

You are right - this program can't correct the Ghost situation by itself.

But it makes the first step - gives information in easy and fast way.
We (and probably the people in the lab) do not know how much
server HDD space is consumed for months by this Ghost problem.

If the top crunchers like you use this program and report e.g.
"I have ~20000 Ghost tasks assigned to my computers = ~40% of the tasks are Ghosts"
the staff will be informed of how big is the problem
and will be more determined to resolve it shortly.

OH, I can't even imagine the ghosts I have. Nor do I wish to find out at this point.
It's a far greater problem than the kittyman can tackle right now.

Eric and Matt have the ghosts under their watch. And they will not escape.
