1) Message boards : Number crunching : RenderBoxx 10100 and Linux BOINC/SETI computational errors (Message 1955253) Posted 13 Sep 2018 by ab1vl-pi Post: I recently acquired some SuperMicro -based video rendering boxes that feature 2 x Xeon 4 core chips which operate in tandem as one 8 core cpu, 16GB ECC RAM, running at various default clocks between 2.20GHz and 2.6Ghz. These run other projects *fast* and without error. I have 100 concurrent hours of MW@Home and Asteroids@home with no glitches,( Lubuntu 18.04 with latest updates). Note that these have a basic VGA port but no GPU, thus No Usable GPUs is found in the log as expected. When I add seti as a project the WUs download but immediately terminate with computational errors. One hunch is that the jobs downloaded are based on the assumption I have a GPU, perhaps because the benchmark completes so quickly. Also, I have seen some seti WUs that show up in Status as using 2 cores , (Windows dual core machines) so could it be that the app (or boinc) may be getting WUs that are restricted to 2 cores? That are aborting because they can't cope with my 8 core CPU setup? Is there a document that explains seti wu naming conventions so I can further investigate? I have 10 of these 8 core machines and it would be a shame if I could not figure out a way to throw them at seti, since they run WUs pretty fast. Unfortunately they seem to have no usable PCIe slot for a GPU, but I have only looked into one of them so far. tnx in advance

2) Message boards : Number crunching : Remaining column missing in task view tab (Message 1953224) Posted 1 Sep 2018 by ab1vl-pi Post: BOINC 7.12.1 on windows 7, dual core AMD Athlon X2 5600 cpu 6 GB RAM, plus operational Nvidia GT-220 GPU (341.44 driver) does not display the Remaining column. But my WIN 7 Core 2 Duo E8400, 4GB RAM, no GPU (built in Intel Q45/43 Express Chipset) displays the Remaining column. BOINC shows this column selectable under Options/Select Columns but it does not show up in Task view tab. Other columns normal. I tried toggling it on and off a few times to see if I could shake a bit loose and turn it on but no good. If I adjust column widths I get vertical lines that appear and may remain after I stop adjusting column width. But if I shift to another screen they disappear. On the same machine, Linux BOINC with Lubuntu 17.10 shows this column no problem. Since I am running the monitor off the GT-220 VGA port my hunch is this may be an Nvidia driver issue. Anybody else see this?

3) Message boards : Number crunching : SETI@home v8.22 Windows GPU applications support thread (Message 1952243) Posted 26 Aug 2018 by ab1vl-pi Post: Tnx Grant, Amazon has one by NXDA (China) labelled as 2BG GTX 750Ti, for $70.90, about 1/5 of the "pure" NVIDIA price. Any intelligence on NXDA? This would be fulfilled from China ARO 30-45 days. Another concern is trade wars, Amazon boilerplate leaves us open to an new duties. Other than that I'd give it a shot. Unless it was DOA it would probably be a big improvement.

4) Message boards : Number crunching : SETI@home v8.22 Windows GPU applications support thread (Message 1952063) Posted 25 Aug 2018 by ab1vl-pi Post: Looking for Fermi or later GPU Nvidia hardware. As I understand it only ASTROPULSE cares about buggy post 340.x drivers for pre-fermi hardware so I might be open to that too. I have a handful of ASUS mobos with Athlon 64 2x and 4x cores. The 2X with Gt-220 GPU runs blc04_2bit_guppi WUs (showing as v8.8.01 cuda60)on linux and win7, same box. If you have a used GPU you'd like to sell, PCI or PCIe, that is faster than the 1.2 cc the GT-220 offers, I'm interested in talking. If you can recommend a low cost NEW card that offers decent performance, I'd like to hear your recommendations. I don't game, I just want a few decent co-processors to stuff into these systems I rescued from the transfer center. Please use PM. tnx, chuck
