12) Message boards : Number crunching : Why are tasks sent long after the first of the initial pair? (Message 138340)

Thanks for the info. I did not know that the scheduler chose, randomly, from a large bunch of tasks to send out. I just assumed that it sent them out sequentially, choosing the next one that fit within the right parameters (OS, hardware, subproject, not same user, ...).

This is a frequently asked question.

You (Werinbert) would have been 1st if both those tasks were sent out at the exact same time. But sometimes one competitor gets a head start. So sometimes a tortoise will beat a hare. Unfair? Maybe. But at other times it will be the hare that gets the advantage.

As far as we know, the server does favor particular users. It is completely random who gets the head start.

I am not worried about being fair or not, I am probably the beneficiary more than not of these delays. I was merely giving an example showing the long delay between the two initial tasks when I though that the high volumes of requests for these relatively short tasks would cause send times to be similar. It just so happened that I was, in this case, the wingman.

Zombie's thread mentions that some power users can get ahead of the processing curve and thus are making requests for tasks when there are none to pickup the other tasks as a wingman. And thus a large number of WU are created with only one task being sent out. Consequently when a wingman does comes along they are then given the paired task long after the initial task is sent out. This pretty much answered my question.

That said, and after contemplating my navel for a bit...I am still confused as to why the Boinc server assigned the second task without assigning the first task previously. (This also happens to be shown in my example.) Simply, I find it odd as I think of computers as overly methodical. I should probably just chalk it up to Boinc server mysticism and go back to philosophizing the number 42.

Thanks, that answered my question...now I feel like a fool not seeing that thread in the first place.

I have seen a number of tasks where the first/second task is sent a long time after the other task of the pair. I assumed that for the first two tasks of a given WU they would be sent at roughly the same time, but a bunch of WUs have sent tasks 45 to 60 minutes apart.

Example workunit: https://www.primegrid.com/workunit.php?wuid=646362573
for this WU the first task (1071108054) was sent long after the second task (1071108055).[/url]

I should probably eat my words....After going through the individual match-ups I noticed that I did in fact get first against your RTX 2070 twice. But that doesn't stop me from envying you.

It has gotten better since I wrote the post. But I have to thank the server for sending out the wingman's WU many many minutes after sending the WU to me.

And...it is many of your GPUs that are crushing mine. ;-P I dream of getting the RTX GPUs, unfortunately they put out way too much heat for me.

Regardless of the state of the GPU bake-off (it will be a memory in three weeks), I think it would be interesting to see the volume and variety of GPUs that people provide for this project. I know the computer type link on the left shows much of the variety but it doesn't show whether the GPU is common or uncommon. And info on the web is generally geared towards gaming rigs not crunching rigs. Since the e-coin people have mostly moved on elsewhere, what we have left are the cruncher crowd both dedicated and casual.
18) Message boards : Number crunching : Linux vs temperatures....help? (Message 137696)
Posted 258 days ago by Werinbert
Thanks all. For now I am just using K10temp for core temp, not good but sort of works. (Too bad TThrottle doesn't come in a Linux package.) My computer generally runs in the 80c to 90c range. The Zen2 boosting is making things weird and hard to drop temperatures.

@TimT, I tried lm-sensors to no avail, there are problems with it and other related drivers trying to access the sensors on the new Ryzen 3700X (possibly all Zen2) chips.

I am also trying to get the it87 going but that seems to be having issues that are beyond my skill. Looks like more reading and learning is ahead for me. If worse comes to worse I will just have to wait until Kernel 5.4 and hope that does the trick.

Is there anyplace that states the number of GPUs by type connected to PrimeGrid?

I normally would think my GTX 1660 Ti to be a good GPU, however, I seem to keep matching up against RTX GPS. Where are all the smaller GPUs for me to bully and get firsts? For what it is worth, my 750 TI has resolved itself to just hunker down and wait out the TdP. Who would have thought that prime finding was such a rough and tumble affair...

Many years ago my previous PSA cruncher died, so I stopped doing PSA work. However, a couple days ago I decided to restart my PSA effort.

And for my effort I got this yesterday and this today.

Unfortunately, I am a victim of my own success and have been waylaid by RAC limits on adding PSA credits. Thus the I should have attained today will just have to wait a couple more days as the remaining credits move from pending to credited.
