It would appear some change in the App has brought the DECADE old problem of BOINC not knowing how to count slots Home to Roost. Before now BOINC has always been unable to count slots on a Mac Pro but the CUDA part worked anyway. I can't remember but does BOINC always call the card with the monitor Device 0 no matter which slot it's in? Along with that it seems to always number the OpenCL devices different than the CUDA devices. Remember, it works Fine with zi3v, and all previous App versions. Now that I think about it, I think I've tried three 1050s before, and BOINC still claimed at least One of them was a Pre-Fermi card and counted the OpenCL devices backward.
I'll have to think about this one. The New card should be here early next week, but now I'm not sure it will help.

See, the 1050 works fine with zi3v, Best pulse: peak=9.008863
960 works with zi3v, Best pulse: peak=5.853899
1050Ti has No problem with zi3v, Best pulse: peak=5.75655

I don't know if it is different with ATI cards since I have never run them, but BOINC seems to follow the Nvidia Settings app which always calls the Device0 which is Monitor 0 and the card connected to the monitor. And that may not be the highest ordered or lowest ordered slot on the motherboard. I've had the card in the middle of a card sandwich labeled Monitor 0/Device 0 because it was connected to the monitor. It is a bit of a mess with the later Nvidia drivers. I don't think there were issues back on the 384 or earlier drivers. The problems started with the 390 and more so with the 396 drivers.

As you well know, I, Zalster and Juan have had issues with the cards being re-enumerated and Device ID's changed with the later drivers and running the nvidia-xconfig application. I don't know if something similar is happening on your Macs.

I do know the BOINC problem with the Mac Pro is at least 6 years old, it probably goes back to when it was released 10 years ago. Right now this is what it's saying;

According to that, the 1050 & 960 are Pre-Fermi GPUs , and it has them listed backward in the OpenCL listing. But, as you can see, zi3v is working normally. The Slot problem has been around for Years on the Mac Pro.

Well, after some thought I've come to the conclusion the problem is probably the Elephant standing there saying your Pascal GPUs are really Tesla GPUs and can't be used by BOINC. The difference between the machine that works and the one having problems are the BOINC messages saying It can't use your cards. The Slot numbering is the same in both machines. BOINC won't use the cards for OpenCL, but by some miracle it does work in CUDA...mostly. That would mean something similar to how the Linux Jumping Task page was fixed. Go back in the BOINC code and find the section that can't tell the difference between a Tesla and a Pascal and Remove that section. The problem would probably go away once BOINC stopped calling Pascals Teslas. The only way I got the 1050 to work last night was by removing the 950. Then BOINC only claimed the 1050 was a Tesla, instead of Both being Teslas. It worked after that. I then added the 950 back and it still worked even though BOINC claims both GPUs are Teslas and can't be used. Time to Stop ignoring the Elephant.

. . OK, one problem sort of solved, that's progress.

. . Meanwhile, I have re-installed Lubuntu 3 times on the new rig but every time it comes up with pretty much the same symptoms. I cannot drag and drop apps into a terminal with ldd, but by navigating to the directory and typing the app name the dependencies list and are all there. Although I can install the repository nvidia 390 drivers, whenever I try to use the recovery method for 396 drivers the system goes off into limbo when I try to enable the network. On the last attempt to re-install Lubuntu I scrapped the partitions and installed totally fresh. The updates all happened AOK but though I re-installed BOINC 7.8.3 and copied the backup over the client_state.xml et al as soon as I launch BOINC it wipes out the backed up files and creates a new empty client_state file demanding I select a project.

. . For some reason Lubuntu hates that hardware.

Why you not install Ubuntu instead? It's works with little pain even for those who have minimal (or none like me) Linux knowledge.

I forget. Why do you want to install Lubuntu? As Juan says, Ubuntu is easy to install and just works.

. . They are essentially the same platform, Lubuntu is kind of Ubuntu lite ...

. .Mainly I am trying to find a Linux platform that will be most friendly for non-Linux using people with a Windows background. Lubuntu feels much more familiar for a Windows user than normal Ubuntu and without needing to know the difference between a Gnome or LTE or LTEX or whatever desktop/GUI. I have to say it does meet that requirement fairly well.

. . But I have to wonder if I will have any more success with normal Ubuntu.

. . I guess since I am already back to square 1 it is the next step. But when trying to find repository apps for the cruncher Ubuntu 18.04 is much more confusing than 14.04. There are thousands of apps and they are all lumped together making it very hard to find just what you want.

For some reason BOINC isn't buying the details in your client_state file. For most of us all you have to match is the <hostid></hostid> and <rpc_seqno></rpc_seqno> for BOINC to use the ID. If you are trying to use the Ryzen machine in your computer list you would need to use the numbers on the Webpage with the <rpc_seqno> number One number higher than on the Webpage, I.E.
<hostid>8569708</hostid>
<rpc_seqno>54</rpc_seqno>
It's the same for assuming any old Host ID, use the same <hostid>XXXXXXX</hostid>, and a number One higher than the last time the Host contacted the server <rpc_seqno>XXX +1</rpc_seqno>
It seems you're still having Networking problems. Did you do as I suggested and NOT install libcurl3 on the new install? It seems there is a libcurl3 already installed by default, so, Don't try installing another one, just run the updates and then install libwebkitgtk-1.0-0. I don't now why you would have problems with using partitions, all my Linux machines have separate partitions for Home, System, & Swap. From what I remember, drag and drop doesn't work in Lubuntu, which was about the only thing I didn't like about it.

My problems appear to be solved. I kicked the Elephant's sorry butt out and went back to One version of BOINC before they added the creature. No more messages saying my Pascals are Teslas, and everything except OpenCL seems to be working OK. I can even surf the Web without Missing Pulses. Perhaps I won't have to build a new version of BOINC , 7.4.23 seems to do everything I need. Too bad those OpenCL device numbers are backwards, but, I don't use OpenCL anyway, and I definitely Don't need a Screensaver.

Exactly, That is why some things like dropping file onto a terminal don't work. Because it doesn't have all the features or ability.

Lubuntu is targeted at lightweight hardware. NOT as something that looks like Windows. Ubuntu Budgie is the distribution that looks like Windows. Lubuntu uses the LXDE or now the LXqt desktop interface. The desktop interface is very complicated and where most incompatibilities occur. As you have found out. That is why we suggest the Ubuntu distribution with the its Gnome interface. I don't think you have lightweight or underpowered hardware, so question why you are limiting yourself to Lubuntu. If you insist on a Windows looking interface, use Ubuntu Budgie.

. . OK, so the next step is to re-install Lubuntu without adding libcurl3. Juan confirmed the lack of drag/drop in Lubuntu, and that is fine I can live without it, I just needed to know it is not another problem to be concerned about.

. . There is no problem with partitions, but the first two re-installs I just installed over the existing partition and Lubuntu basically just did an update/repair type of install, so BOINC was still there and still sort of functioning in the way it had been. On the third attempt instead of choosing "do something else" I selected "remove Lubuntu 18.04 and do a completely new install". This went fine, did all the updates etc but still unable to enable networking in recovery mode and other problems. If you were asking why not create separate partitions for system (root & boot partition) and /home it is because I was trying to keep the process as simple as possible. I just have the 2, system and swap. If I had used 3 then I might have avoided the BOINC problem but sadly that is too late now. (initially I was installing to flashdrives that had insufficient capacity to use too many partitions. I could have done that with the SSD but I was sticking to the original plan)

My problems appear to be solved. I kicked the Elephant's sorry butt out and went back to One version of BOINC before they added the creature.

Ubuntu 18.04 uses the Gnome 3.26 desktop as default. You don't have to select anything.

Although I can install the repository nvidia 390 drivers, whenever I try to use the recovery method for 396 drivers the system goes off into limbo when I try to enable the network. :(

Stephen,
It is my understanding that you don't need anything beyond the nvidia 390 drivers to run CUDA91 (I would swear Tbar said so) so I would simply stop trying to push that bolder up the hill and get on with the rest of it.

The worst that could happen with having 390 installed is "computation errors" rather than melting down the computer.

HTH,
Tom
