Well, 'caves' (aka underground cavities) can very well be gas-tight, that's where the natural gas comes from.

Yes, no separation work for my hosts either unfortunately.

Where these 11 million N-body tasks came from?! I thought that mess was cleared uu bu apparently not....

Nominally, the RTX 3060Ti should be 2.5 times faster than GTX 660Ti (that is in terms of FP64 FLOPs - 253 GFLOPs vs 110 GFLOPs). This should be a noticeable difference, something like 8 simultaneous WUs vs 4 simultaneous WUs completed for a similar time.

If you will also Read the News Forum you will see that the Server lost a harddrive a while back and replacing it took time and not getting it back upto speed is not going very well BECAUSE we keep using the remaining harddrives to get and return work. They have already had a day here and a day there to try and make things go faster but it just isn't. And THEN we have people complaining that their own tasks aren't going to be validated in time so the Admins capitulate and turn the Server back on again slowing down the new drive being part of the whole Raid group again.

In short if it bothers you that much try crunching something at Einstein or Collatz until MilkyWay is caught back up again. Unfortunately they can not afford a full time Admin so the Admin also teaches at the University and that involves more than just classroom work as any teacher can tell you.


Well, I am well aware of all that and I was merely pointing out that there is still a problem with the 'pending' tasks with the idea that the admins might want to do something about it (if they are so inclined). Also, most of these are WUs that I have completed weeks ago (even a month ago), so I don't see how it'll help if I decide to switch to Collatz full time now, (or even a week ago, or even a couple of weeks ago).

In any case, I don't see this topic as a place for other contributors to comment on my understanding of the inner workings of MW@H, hence my previous post.

He has already been told this many times, but he does not seem to be willing to unsderstand !
Excuse my bluntness - I just had to say it ...
Have a nice day


Look here old chap,

Your bluntness cannot be excused.
I understand fairly well how MW@H should work (also thanks to the useful comments from other contributors here). However, it's pretty obvious that the project does not work as intended at the moment, does it?
Now, some of these inconclusive WUs started to appear in the 'error' pile (several hundred of these already) as 'timed out - no response'. They are not going to be 'validated at some point', are they? That's what I call a pure waste of my time and resources.
In my opinion, it's useful when there is a problem to point that out. Whether the admins want or can solve it is another matter.
From my 'non-understanding' point of view, the admins should have canceled (deleted, purged... as a more knowledgeable person you can insert the right term here) all these compromised tasks and started with completely new and fresh WUs. Instead, they are circulating millions of these WUs from a month ago again and again through the hosts resulting in the current waste of time and money.

So, I'd suggest that, if you don't have anything useful to contribute, just keep your comments to yourself.

A great deal of my current WUs go straight to the 'validation inconclusive' pile. Also, the majority of my 'validation pending' WUs went straight there, too. To me, that is very disappointing, a pure waste of my time and resources.

Most of my current and past work went to 'validation inconclusive' pile. Quite disappointing. The WUs are duplicated but for some reason both results are unsatisfactory. The third copy of the WUs are just 'unsent'. Such a waste of time and resources.

Yes, many people experience similar problems (erratic WU supply). The reason is that there were some issues with the project server recently (see https://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=4863 and the other related threads in the News section). As far as I can tell the issues are not yet completely resolved but there should be steadier WU supply now.

All best

Same situation here, my stats say 622 tasks in progress, although none of my machines has received a single WU in the last 16hrs. The WU request either gets 0 tasks or a message saying no work is available.

Yes, unfortunately, something is still not quite right with the server. I can confirm that none of my hosts are getting work (as per the two previous posts). Yesterday, after a lot of manual requests I got a handful of WUs (far less than the max amount per host) and that was it. No work since then.

May your completed WUs are still in the validation queue


maybe, or maybe not... one can only guess

So, who cares about RAC?
We are here to crunch for science!

Exactly, for science, not just because I fancy wasting my money and resources. But where is the science output from the completed tasks in the last 3-4 weeks?
We are achieving results, they are being received at milkyway (sooner or later) and you will get credits.

According to the server stats, nearly 4 million tasks got validated recently (at least they disappeared from the validation pending stock), but did not materialize as valid tasks with credit... where are they?

I don't see why you're getting so upset about it. Join more than one project then you won't even care when one isn't available. It's not like they're supplying your wages or food.

Well, it's the other way around (more or less) - we (at least some of us) are spending our money/resources to help with their research and it's only fair to get the best possible use of our resources and not waste our money.
I do MW@H because I like that kind of science and I am interested in the broader topic (cosmology). However, if my machine time and money are going to waste here I'd like to know that so that I can rearrange my priorities.
The only updates from the admins are very vague - 'just going to switch this and that off... going to purge whatever... things are going to be slow for a bit... the server is a bit unstable... etc.' which is not very helpful. Besides, whatever they do on their end, does not improve things on our end so far. The server keeps limping with erratic WU supply and, as far as I can tell, wasting our money and resources.
I'd like to see more detailed updates on what is wrong with the server, are there any plans on how to fix it, what is the time scale, etc. Even if the admins have no idea what is wrong and how to fix it (nothing wrong if this is the case), it is only fair to inform us so that we can plan accordingly.

The number of tasks pending validation dropped quite a bit recently (from 6+ million some time ago to less than 2.5 million now), yet my RAC keeps plummeting and the last validated tasks are from more than a week ago. For all I know, most of my work in the last 3 weeks has been a complete waste.

I think the RAC from past work (pending validation) is beyond salvation. The hope is that, at some point, the server would start to operate normally and we'll be able to build up RAC again. Although, I'm not very optimistic given the only thing the admins tend to do is to switch off and on services and hope for the best.

Currently turning some processes off to flush the transitioner backlog. Once that's done I'll turn things back on.

Hi Tom,
was your intervention successful?
On the receiving end of the server nothing changed much, unfortunately. No WUs are being sent (despite that the server status says there are plenty). It seems the server reports numbers that are completely wrong. For example, the server says I have several hundred WUs in progress while, in fact, the last WU my host completed was more than 24 h ago. It seems the server is still a mess and it's a shame that the admins do not care too much about it. I moved my host to other projects entirely now... why should I care about MW@H when even the admins don't.
All best,

Well, I did try all sorts of 'gymnastics' (maybe not in that particular sequence, but definitely suspend, restart, etc... all that). This is just ridiculous, there shouldn't be any need for that sort of babysitting. The admins should sit and spend some time to sort the server issues completely and not do a piecemeal job of scratching here and there and hoping that things will sort themselves out.

Still, no regular supply of WUs for me despite the server status is all green and plenty of 'available' WUs to send. Verry intermittent supply of a few tens of WUs to a couple of hosts. I was hoping that by now the server should have been sorted. It's getting to the point of being really annoying and thinking about moving to a different project all together.

I have several validated tasks from the 13th and one from yesterday. Seems some validation goes on, but I still have 30+K pending tasks.
