Hello,
I have not received any work units in over two months. Do I have a problem on my side or is it on your side?
Thanks,

HI Daniel, the lack of work is project side. There is hopefully some work coming later today or tomorrow morning but it is for Linux machines only if it arrives. (There have been some problems with the batch.) I am afraid I haven't seen any clues as to when the next batch for Windows machines is due.

Hello there, I am in the same situation, except I have not been assigned new work since June, just glad not to be alone and not an issue my end then...

Cheers

These are the Windows batches released since June:


841 1200 2019-10-03 Oregon
840 1450 2019-10-03 Oregon
833 500 2019-09-19 Oregon
832 600 2019-09-18 Mexico
829 3000 2019-06-23 Oregon
827 1200 2019-06-21 Oregon
823 860 2019-06-13 Mexico

(batch, number, date)

As can be seen, there's only two research places that have been active, and three of the batches have been small.
Any computer that hasn't picked up some of these, is probably running other projects as well, and the computers just didn't need work for the brief periods when work was available from cpdn.

The N216 have arrived. I have them running on 11 cores of an i7-8700 (with one core reserved for a GPU), under Ubuntu 18.04.
They are taking 1348 MB each according to the BOINCTasks. The estimated run time is 3 days 14 hours, but that is only after 1/2 hour, so I would not place much credence in that.

UK Met Office HadAM4 at N216 resolution 225 59 server status page showing a much lower number - total of running and unsent 284 which is just because it is out of date. If that is all there were, there wouldn't be any left for me to download and two are doing so now but they won't last long!

Is any work being sent to machines with AMD processors? The only machines I have that don't have work are machines with AMD processors. These are Linux machines.

There are only three things that matter for a computer to get work:

It MUST have all necessary 32 bit libraries
It must have sufficient memory, which is starting to get to 2 Gigs minimum per model
It must actually need work, as decided by BOINC

AMDs work fine. Make sure your computers have the right 32 bit libraries installed. See this post for more info...

I got one:

 
USER    PR  NI S  VIRT  RES  SHR  %MEM %CPU  TIME+      COMMAND

It is only 3.5 hours in. Predicted time to complete is 349 hours, but hadcm3s and hadam4 144 tasks seem to run about twice as fast as predicted, so I suppose these will too. OTOH, this one is predicted to run in about half the time of those others. Working set (of my 16 GByte RAM) is1.3GBytes or 8.5% OF RAM. So I could run on all four cores.

And there is now a second batch of 3150 of these in the hopper (batch 843, first was 842)

#844 Mini batch of 259 hadcm3s were released late last night. (UK time)

Please if running a Linux box go to the Linux section and read the bit about 32 bit libs. The overwhelming majority of failures for both hadcm3s and hadam4 tasks are because a required 32 bit library is not installed.

Mine look like these:

$ ldd hadam4_8.52_i686-pc-linux-gnu
	linux-gate.so.1 =>  (0x00ba3000)
	libpthread.so.0 => /lib/libpthread.so.0 (0x007c3000)
	libdl.so.2 => /lib/libdl.so.2 (0x007eb000)
	libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00c8b000) <---<<<
	libm.so.6 => /lib/libm.so.6 (0x00aaf000)
	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00c1e000)
	libc.so.6 => /lib/libc.so.6 (0x0062a000)
	/lib/ld-linux.so.2 (0x565ed000)

$ ldd hadam4_um_8.52_i686-pc-linux-gnu
	linux-gate.so.1 =>  (0x006b6000)
	libdl.so.2 => /lib/libdl.so.2 (0x007eb000)
	libm.so.6 => /lib/libm.so.6 (0x00aaf000)
	libpthread.so.0 => /lib/libpthread.so.0 (0x007c3000)
	libc.so.6 => /lib/libc.so.6 (0x001a8000)
	/lib/ld-linux.so.2 (0x5657c000)

It seems to me that boinc runs hadam4_8.52_i686-pc-linux-gnu first which forks off hadam4_um_8.52_i686-pc-linux-gnu to do all the work. When that is finished and exits, then hadam4_8.52_i686-pc-linux-gnu finishes up, calling something in libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00c8b000) this is not there, and then fails. It would be nice if hadam4_um_8.52_i686-pc-linux-gnu would make a dummy call into thelibstdc++.so.6 up front so that it would fail right away, rather than a week or more later when processing is almost complete.

If that file isn't there, the task fails after a few seconds.
Some examples here

I don't recall seeing tasks failing after a week or more processing due to missing libraries.

Just looked at batch 826- (a hadam4 batch and a sample of about 20 hard failures .) All of the failures due to missing libs were at less than 5 seconds. failures after some credit had been granted were all either segmentation violations or invalid theta so problems with the actual tasks.

Thanks for the reply, they were missing a few of the needed 32-bit libraries. One of the libraries (lib32ncurses5) was not found when trying to install. Installed lib32ncurses6 and that seems to work OK. This is also running on Ubuntu 19.10. This machine has downloaded 16 WUs so far so all seems well.

Some Windows work: 7160 x WAH2 global, batch #845.

Yes it was a nice surprise I managed to pick up 21

Something funny happened with 21752443. i find it sad he had 11 trickles and uploads (I suppose) only to bomb. But something else was probably going on too. All those

I happen to be running this one: 21759319 and it seems to be OK so far.
