Apologies for going off track here, but there is never a reason for a CPU to be too hot. Improve the cooling system. 17 W/mK heatsink paste, bigger cooler, faster fan, etc.


My fans increase in speed as the box temperature, processor heat sink, etc., increase in temperature. But they do not increase fast enough, so I have diddled the BIOS to run the fans faster. But I have them set up so they make so much noise that I can't stand to run them any faster. There is no room in the box for a bigger processor heat sink.

These are how my system is running at the moment. Ambient air temperature is 74F

I second this, I have machines with up to 128GB RAM. Limiting those to the same number of tasks as 16GB machines is illogical.

Me too. My Windows 10 machine has about 16 GBytes of RAM (total), but my Linux machine has 128 GBytes of RAM.

The Linux box has a 16-core processor and I am letting up to 13 Boinc tasks run at a time. In warm weather I first cut it down to 12 Boinc tasks and when it is really too hot, I cut it down to 8. I run CPDN, WCG, DENIS, Rosetta, Einstein, Universe in order of decreasing priority.

It may be intermittently available while they're working on it?


My test shows the site is up, but when I go there, I get this:

 
Ubuntu Logo
Apache2 Default Page
It works!

This is the default welcome page used to test the correct operation of the Apache2 server after installation on Ubuntu systems. It is based on the equivalent page on Debian, from which the Ubuntu Apache packaging is derived. If you can read this page, it means that the Apache HTTP server installed at this site is working properly. You should replace this file (located at /var/www/html/index.html) before continuing to operate your HTTP server.

If you are a normal user of this web site and don't know what this page is about, this probably means that the site is currently unavailable due to maintenance. If the problem persists, please contact the site's administrator.

An OpenIFS linux batch will be released in the next 7 days. It's about to go into testing. This batch is based on the earlier batch 993 but with reduced model output (and hence smaller upload files).


My most recent one of those was this one. It worked, so perhaps this new batch should work too. Right? I must have those compatibility libraries in there although, IIRC, these OIFS programs do not need them.

Post:
If any process is quit, it will not completely die until it's closed open files. I think what Dave might be referring to is flushing any I/O buffers held in memory to a hardware drive. Although code can 'tell' the OS it wants that done, the final decision is still made by the OS. Both the CPDN task & Boinc has a wait-time built into the code to allow any buffers to be flushed but again it's can't be forced.


In "modern" versions of Linux, and perhaps other versions of UNIX, you can greatly increase the chances that IO buffers are actually written to disk (at least to the input buffer of the drive itself) by calling the fsync() command.

https://www.man7.org/linux/man-pages/man2/fsync.2.html

Here is part of the description.

DESCRIPTION         top

       fsync() transfers ("flushes") all modified in-core data of (i.e.,
       modified buffer cache pages for) the file referred to by the file
       descriptor fd to the disk device (or other permanent storage
       device) so that all changed information can be retrieved even if
       the system crashes or is rebooted.  This includes writing through
       or flushing a disk cache if present.  The call blocks until the
       device reports that the transfer has completed.

       As well as flushing the file data, fsync() also flushes the
       metadata information associated with the file (see inode(7)).

       Calling fsync() does not necessarily ensure that the entry in the
       directory containing the file has also reached disk.  For that an
       explicit fsync() on a file descriptor for the directory is also
       needed.

However I was taught ALGOL


I started with assembler for the 704 IBM computer (5000 vacuum tubes. IIRC) and then used the original FORTRAN for it for some things.
When Illinois-ALCOR Algol 60 came out, I really liked it for mathematical work, and SNOBOL4 and SPITBOL for text type problems. I even wrote a compiler for a special-purpose language in SPITBOL.

I seldom write program these days. I am most at home with C and C++ currently.

Not to mention that internet bandwidth is not a zero-cost resource, in either climate or financial terms.


The incremental bandwidth for me took a big step-up recently when Verizon replaced my FiOS hardware. My old hardware was installed in about 2004 and they did not want to support it any more. The new is about 10x faster than the old.

I have received three tasks, one at a time, that are all working fine on my Windows10 machine. One is 1002 and has returned three trickles, and two are 1003 and one has returned a trickle and the other not yet. They are all running at once and they are predicted to take almost 10 days.

So you probably would not get any tasks either after that. They are very few and far between.

Left the PC on overnight.
The task that was running last night is still running this morning.
However a new task arrived, and promptly crashed (less than 2 minute running)

https://www.cpdn.org/result.php?resultid=22344887

, with a segment violation error. So it looks as if that problem, while reduced, is still around.


I wonder what your problem is.
My three tasks are still running and have now uploaded 5 trickles.

All but one of the failures was after shutting down for the night. It's somewhat reassuring that it's not my computer that's got an issue, ut it's a bit disappointing that the stop/restart issue hasn't been fully cured yet.


That may be why I seem to get less crashes than others. I let my machines run 24/7 and reboot them only when installing updates.

Don't want to dual boot as this is my main machine and non BOINC work all happens in Linux.


Good Idea.

I, too, hate dual booting because I run almost everything in Linux. I need Windows only to run TaxAct each year to do my income taxes (Federal and my state). And four times a year to keep my Garmin GPS unit up to date.

I could get a Windows license to run Windows on this machine, but a few years ago I got sick of that so I got a little desktop machine (It looks just like a monitor, but the computer is inside the Monitor.) And that little computer runs Windows 10 and has nothing else to do, so I downloaded Boinc into it.

I signed it up for CPDN, WCG, DENIS, Rosetta, Einstein, and Universe.

My main machine is ID: 1511241 and has lots of RAM and processor cache. And my pipsqueak machine is ID: 1512658 and has much less RAM and a slower Processor that is only 8 cores. My Linux machine has a pretty fast processor with 16 cores.

Had hoped that the signal11 failures would be a lot lower with this batch but it seems this might not be the case. This is to do with the batch and not your computer. Just hoping there are enough good tasks between this and the last lot for the researcher to get what she needs.


I have only one computer running Windows and I do not run WINE on the other (Linux machine). How do you distinguish between failures due to the machine from those due to the batch? I assume mine are all from the same batch and they show no signs of failure yet. I guess you see results from many other machines so you have more data from which to draw conclusions.

My three work units have about two days of work done on each. Each has uploaded 3 zip files. No failures yet. These are on my Windows 10 machine.

I don't trust WINE for running the model correctly. We discovered during testing that WINE implementations do not fail the model when it suffers a memory fault unlike on bare metal Windows. I think there is some memory protection in place for WINE. That implies the results from incorrect memory addresses (e.g. maybe zero) are being used by the model, potentially corrupting the results.


I think memory faults, WINE or not, are an indication of an incorrect program or a hardware fault. If WINE has some memory protection in it in addition to the hardware, perhaps this is just more proof of my theory. It seems to hide the memory faults.

When I first used Windows (Windows 95) it had so many faults that it crashed several times a day even if it was not doing anything. I did not run BOINC then (I do not remember if it existed at that time). Since then Windows has improved some. IIRC Windows 7 was pretty good and I am now running Windows 10 on my other machine.

The three current tasks on my Windows machine now have about 18 hours on them with about 9 days to go.

The task on my Ryzen running Windows natively failed at the usual point with a signal 11 (segmentation fault) during the first model day. Tasks running under Wine appear to be progressing nicely.


I have three of those tasks running on my Windows10 macine. They started at about one-hour intervals and have about 1.7, 2.7, and 3.7 hours completed.
About 9.5 days for them to complete. 8-core machine running on 7 of the cores. Machine not doing anything else (except 4 other Boinc tasks).
