Message 61729 - Posted: 19 Dec 2019, 8:16:02 UTC

I started posting in the 32 bit thread but figured I'd bring my issue here, since it's still not resolved.

Just got this, despite work being available according to server status. Followed the instructions in the prudent thread, typed in the following before installing Boinc 7.16.3:

sudo apt-get install lib32ncurses5 lib32z1 lib32stdc++-6-dev


12/19/2019 1:59:14 AM | climateprediction.net | Sending scheduler request: Project initialization.
12/19/2019 1:59:14 AM | climateprediction.net | Requesting new tasks for CPU

12/19/2019 1:59:15 AM | climateprediction.net | No tasks sent

This is on a fresh Ubuntu 18.04.3 install. All OS upgrades complete as well.
Same OS on 2 other machines having the same issues, one since September. I took it to mean no tasks available for Linux, but didn't really pay it much mind until I noticed this. This is on a machine, the 2600, with more log flags enabled. Does this help?

12/18/2019 11:39:55 PM | climateprediction.net | [sched_op] Reason: requested by project



The machines in question are 1496269, 1496255, and 1493090.
What other information can I provide? I guess this Ryzen 1700x will be crunching another project for the time being. 64 GB of memory and running on an ssd complete this.
I'd love to contribute more to this project but for some reason something is failing to compute as it were on my Linux machines.

Truthfully it's a little frustrating that it could be as simple as a library not installed, but you would think tasks would at least download and fail. I'm not even getting that. I hope this project can get around to being 64 bit soon.

Any help appreciated.

Agreed, nothing to do with 32 bit libraries. There are machines out there that don't have them, download tasks and crash everything.

Your computer https://www.cpdn.org/show_host_detail.php?hostid=1496269 Is showing number of times client has contacted server as 0 but that doesn't explain the other two. I am running 7.16.3 so I don't see how that can be an issue.
Edit: lots of others are using it so any minor differences from having rolled my own from the source at Git Hub won't be the cause.


I am clutching at straws here. Are your windows machines at the same location? If not I wondered if it is something to do with your ip address being part of a block that has been shut off by CPDN/.

I don't really think this very likely but if these machines aren't chocker with work from other projects which I am pretty sure they aren't from what you have said, like yourself I am running out of ideas.

Very, very strange. I assume you still had all the Ubuntu updates enabled when you did the 32-bit install? I usually disable them at the end, and then if I try to install something it may not work.

Otherwise, I would detach from the project and try again, hopefully with a new computer ID. It seems that the server thinks it has just sent you something, and is doing the usual one-hour back-off.

Nope, the Ryzen was freshly added as of 10 or so hours ago and CPDN was the first project to be thrown at it, with Universe at home at 0 resource and CPDN at 300.
These are machines running in a Hetzner datacenter, I'm not sure if this would make any difference in terms of IP as I do have a Hetzner Windows machine (though all the IPs are different blocks I think) but the Windows machine gets work without issues when work is available that is.

Forgive the perhaps stupid question, but what do you mean by disable updates? I'm not sure how to go about doing that - I'm assuming you meant disable updates for Ubuntu itself after I install the 32 bit libraries?
Should I reset the project, then remove it? Maybe I'll detach from BAM too just to be on the safe side. Of course, my lowest end machine with a core 2 duo is sitting here getting tasks without issue on 7.9.3 (or whatever the latest Ubuntu has to offer), at least as of 18 or so hours ago, and I don't understand why.

Sorry for the double post - I can't find an edit option. Time to grab a beer and take a break from messing with this - literally just found the edit option after I posted this. Clearly my brain is dead.


So since crunching is all these are used for, I just completely wiped this machine [url]https://www.cpdn.org/show_host_detail.php?hostid=1493090-/url] and installed the libraries plus 7.9.3. Apparently when I attached again, this time without bam or any other projects, cpdn still sees it under the same ID as last time, despite resetting it before I removed it previously, so now I got a communication deferred for 58 minutes message and we'll see what happens next.
Hetzner offers 2 versions of Ubuntu 18.04 - one called Minimal, which is what I've been using and another that also includes nextcloud, which I'm trying now. I highly doubt this is the issue, but I have fingers crossed.
If it still doesn't fetch tasks, at this point I'm at a complete and utter loss. There are no firewalls installed, all ports are open, and any other project I attach to gets work, including Rosetta, WCG, Universe, even LHC provided everything is correctly installed.
I'm mainly renting these due to lack of physical space and for $28 a month for a 4770, it isn't horrible. Of course long term it will get expensive, but right now there is also a Ryzen 3600 on offer at $43.
Of course if I can't get these crunching here at all....
Would I break anything if I tried installing the needed libraries for Ubuntu 1604 as well? Just grasping at straws here at this point.
It also doesn't help I'm so very new to Linux and all it has to offer.

Edit 2: Looks like something I did forced it to start actually downloading tasks. This is fantastic! I wonder if starting from Boinc 7.9.3 forced it into action. I'll upgrade to 7.16.3 when these tasks finish and see if fetching continues, which I have no doubt it should. I'll do the same on the other two machines that are currently struggling to receive work.

It is done via the check boxes in "Software & Updates". It looks like you have not done it, so don't have to worry about it.

Generally, yes that is the idea. But I don't use BAM, and don't know anything about it. Just make sure you fully detach, and try again.

I tried that before reinstalling completely and for some odd reason, it was still failing to download tasks.
I have a machine here locally that I need to get some ram for and I'll test that theory. Update Boinc to 7.16.3 before attaching to the project. I doubt it will make a bit of difference and am assuming something was off in the first Ubuntu installs.
The other difference is there is no bam this time and likely won't be in my future either. The interface is awful now and I'll just use boinc tasks to manage everything.

I am reading every post and will keep on reading. I have installed Linux on two laptops. Two instances of Mint OS and one of Zorin OS. Zorin on command line downloaded 32-bit lib but Mint has a sullen face in both the instances. I am not being able to get WU's on any VM? I will check again in the morning, past midnight here.
Any light that can be shed would be much appreciated.

It would also be worth a look at the special threads in Number crunching for the HADAM4 models, especially the N216 model.
They require LOTS of memory.


For sure. And they are not the worst: some Rosetta@hoe tasks are even bigger. I even doubled my RAM size from 32 Gigabytes to 64 Gigabytes to deal with those

Notice the RES is about 1.4 gIGig, but this is only near the very end. Most of the time it is "'ONLY" 1.3 Gig.
