Save in ANSI encoding it said in one project forum thread. Can be selected at bottom in the Save As screen of Notepad.

Save in ANSI encoding it said in one project forum thread. Can be selected at bottom in the Save As screen of Notepad. Ah but SekeRob I'm using Macs and the text edit app (strangely) does not have a 'Save As' tab and also when asked for a format in which to save, plain text (ANSI) is not an option. You have to select Format from the menu bar and then you have the option of converting an RTF or XML file to plain text (with the extension .txt). Having done that then I copied into the appropriate location and changed the extension to .xml. As I said before - no errors flagged up by BOINC now but my cache of MIPs has yet to reach the crunching date so I wait and see how effective it is. Thanks again for your help and support.

To me it looks like there is a significant drop of points per hour. I get around 12 points /hour on an i7 with 16GB RAM, running only three threads and 50% CPU-time each.
Last month I got much more point per hour of runtime. |

Found a discussion over at https://apple.stackexchange.com/questions/188...scii-only-editor-for-os-x which may help simplify the macOS ASCII file creation and editing. Anyway, glad you got no more reading errors, noting that boinc is also quite able not warn at all when using tag that don't belong at all. |

OK so I have just this minute processed my first MIP since starting again. I loaded the recommended app_config.xml file and WUs seem to process in pairs. So far so good. Although BOINC is predicting a 6h 50m WU crunch time the WU actually completed in a little under 1h 30m.
----------------------------------------I hope this is an anomaly but the Valid result was 1.38h CPU time with 1.42h Elapsed. Gain? 14.4 points for a 24Gflop file. This is a joke! I'll check thing out tomorrow morning but if this is typical I am binning my MIP WUs and waiting until sanity returns

Just for the record: my hosts seem to ignore the setting defined in app_config.xml.
----------------------------------------According to boinc event log, cc_config.xml can be read but app_config.xml seems to be completely ignored. Cheers, Yves --- The file is pure ANSI without any control characters. |

Therefore I have aborted over 500 WUs and will wait to see what transpires in the future. At least the app_config.xml file worked a treat in that there were only ever 2 MIP WUs running at any time.

Maybe it has to do something with your restart. I am not sure but to me it looks like the points per hour are slowly increasing at my host since I restarted crunching MIP. Beginning at approx. 10 points per hour I reached nearly 20 points per hour and increasing...

The oh-so-smart credit system uses recent device result statistics. If you switched from all core with a performance problem, then switch to just 2 to avoid the performance problem, the server still thinks the results comes off a poor-performer [The benchmark has not changed], so yes, those who can stand the pain, would see their credit recover (per the theory).
----------------------------------------Still getting 24-25 Cr/hr on my 4:4 running octo with SCC seconding MIP... running at just 2.8Ghz, though the machine could do sustained 3.7Ghz (but then on air just runs too hot, and nearly triples the power consumption).

Just wanted to share some experience here regarding the MIP slowdown issue.
----------------------------------------System: i7-3770 (4c/8t) @ 3.4 GHz, 4 GB Ram 1) first ran MIP without any limit. Other projects running at the same time were OET, some Zika and few SCC, but majority was MIP. Credit per hour of runtime for MIP units began to decrease fast, reaching about 15 (boinc) point per hour. 2) limited MIP wu's processed to maximum of 2 through limiting in app_config.xml. Other projects running did not change much. Points per hour of runtime for MIP units increased, reaching about 35 points/hour. Ran this way for several weeks, however, sometimes I experienced the issue, that I received too many MIP wu's. These were not processed fast enough due to the limit, all non-MIP units were finished and the buffer full of MIP units -> CPU ran only 2 threads instead of 8. Began to allow MIP in the device profile only temporarily to avoid this, get some units and turn it off again. Works, but very annoying. 3) Increased limit to 4 MIP units pocesssed simultaniously and thought this might not decrease performance on an 8 thread machine. However, it did. Points per hour of runtime began to deacrease steadily, reaching 20 points per hour after less than a day. 4) Returned to 2), points per hour are still noticably lower than before, but this should take some time to improve again. Added a Ryzen 1700 yesterday and limited MIP units to 3 for now, will post an update if I have any experience here... *edit: a number, how much L3 cache any running MIP unit actually needs, would be very helpful if you can privide that...
