1) Message boards : Technical News : Due to user feedback and an attempt to reduce the load on our servers, we increased the default target run time from 3 to 6 hours, increased job deadlines to 14 days, and added the target cpu runtime option of 2 days (Message 99406)

An observation I have made bothered me. I understand the program generates a random start point, then runs the model to completion. If there is sufficient time left, now knowing the time the model takes on that node, it generates a new random start point and runs again to completion, repeating this until the run time is reached, or at least, running it again would excede the allowed run time. My observation was that if a run of the model fails, ALL the work done in that run is discarded, including, obviously, the earlier, sucessful runs.

My observation is based on the small table of figures I retrieved from BOINC Stats. The two older entries have, admitedly unsubstatiated but not unreasonable, explanations in the thread here. The size of the remaining variations is quite significant.

That would make sense.

It is interesting that the lower numbers are later. I guess the initial surge of interest in Corona faded somewhat. I guess some crunchers thought they'd done their bit.

It was a bit of a surprise to me to find the absolute record day and another, long passed, day in the list of top 10 days for the project. I expected to find the entire top ten from this year due to the Covid issue.

I saw a new BOINC release had been issued. Updated, and all worked again. I guess they had rushed a fix through.

Took a while, the upload list was the largest I remember seeing.

The thread has raised a doubt in my mind. I have my preferred run time set to 12 hours. I know the workunit has a model, it generates a random number, and runs the model to completion. It then looks to see how long that took, how long there is left with my preference, and if suitable, generates a new random number and runs the process again, and again, ad finitum, until it decides there is not enough time to run it again, at that point, it ends the work unit. With the urgency of the current situation, I can see the possibility that the first run of the model had a critical result, but that it was not returned for hours whilst the work unit ran with different random start points. Should the preferred runtime be set down, at least temporarily?

I'm pretty sure it was Folding that had created the effect I was seeing. When I was investigating it, they told me that I could prohibit F@H using the GPU, but then it would run multithreaded. I looked at it because the GPU on that machine was starting to suffer, arrays of dark spots in distinct rhomboidal shapes over parts of the display, so removed the GPU projects from its portfolio. It is running Rosetta and TN-Grid now.

The difference I am seeing is new, I have only seen it recently, and only on one machine, which, coincidently, is the machine I use least. I doubt anything other than BOINC has been run on there for weeks. Use at most is 100% on both, has always been so.

<edit>
Normally, I do not have a screen/keyboard/mouse on that machine. I moved the gear over there and had a look. I saw Foldig@Home was running on there. I looked at that a while back but decided against it - I deleted it from this machine and THOUGHT I had deleted it from the other. That could be an aspect of the effect I am seeing.

This extended run time is actually getting to be a little bizarre! Looking at my results page, the run times do show this extended run time, up by 50%, but the CPU time does not reflect this, that remains fairly static within the realms of normality. A question that arises therefore, is what are these jobs doing. Useless credit varies wildly of course, always been the case.

For information only in case others are worried by this behaviour. It is not just your machine!!!

One of my machines, (4GHz i7), has four odd workunits running at the moment. I have 12 hours set for the target run time, and jobs normally finish around that, but I have four jobs running that are going to be well over that. One is already over 18 hours in. The remaining IS decreasing, but not in a very linear way, it jumps up and down for a while, then drops a bit, then up and down again.

The post a couple back about memory, I fully concur. When I build a system, I always try to have at least 2GB per thread.

>>> sign up for WCG

I, and several others, left wcg about a year ago because of a series of incidents in their forums, it is absent from my machines now. I figured, however, I should crunch them again, at least while the current situation exists. So I tried... I cannot go in. I wanted to ask about this on the forum, it tells me I need to be logged in to post messages, at the top of the same screen is the "log out" poke point, I AM logged in, AND, I'm not!!!

I also have no Rosettas on my machines. A couple of us, ("us" being BOINCers), have been trying to get articles in the current affairs programs on national television. Aim: to get BOINC more generally known. I have found that people are ignorant of its existance, and keen to join when they have found it. Perhaps some have been more sucessful than me, our principle stations have not even acknowledged receipt of my mails. They are, of course, short handed at the moment.

I would ALWAYS advise crunchers to have several projects connected to their machines, so they are not idle when an "emergency hump" occurs.

I've had 5 crashes in the last couple of days, a 1 hour, a 2 hour, a 3 hour, a 6 hour and a 12 hour. All zero credit, so from another thread, I assume this means none of them actually did anything at all. All Rosetta's, not mini's.

Zip the required files for the job, and other files that may be useful for future jobs. Cruncher end task unzips and does whatis needed with the contents. A simple "what to do" text file would probably suffice.

What I guess it should do, is work unit zyyxzyzx has a download issue, okay, leave that one pending and start zyyxzyzx+1. It goes through, fine, issue with the old one, cancel it. If it sticks on the same file, flag that to the staff, and stop sending jobs with that file. It should be robust enough to see and act on enventualities such as this.
