The latest release of genefer (3.3.4) is now released on BOINC labelled as app version 3.20. The client will download the new app automatically, no action is required on your part unless you are using app_info.xml (if you don't know what this means, don't worry).
The new version provides a speed-up of around 10% for AVX and FMA3 transforms for n=21, as well as providing support for multithreading. To enable it, create an app_config.xml file in your BOINC/projects/www.primegrid.com directory containing (for 2 threads per task)
<app_config>
<app_version>
<app_name>genefer</app_name>
<cmdline>-nt 2</cmdline>
<avg_ncpus>2</avg_ncpus>
<plan_class>cpuGFN21</plan_class>
</app_version>
</app_config>
Any problems or questions, let us know! Please note that as the new release does not affect the OCL code, the GPU app versions remain unchanged.

Hi,
I followed your instructions for app_config.xml. Genefer21 is running on CPU with application primegrid_genefer_3_3_4_3.20_x86_64-pc-linux-gnu__cpuGFN21. Unfortunalty MT is not working.
Found the message: Entry in app_config.xml for app 'genefer', plan class '' doesn't match any app versions

Right, we overlooked the need for plan_class in app_config. This is the correct file for 2 threaded GFN-21:
<app_config>
<app_version>
<app_name>genefer</app_name>
<cmdline>-nt 2</cmdline>
<avg_ncpus>2</avg_ncpus>
<plan_class>cpuGFN21</plan_class>
</app_version>
</app_config>
App names and plan_class names can be found on our applications page.

2 questions please.
1: We overlooked the need for pla_class, but in the app config it says /plan_class
so which is correct?
2:Is there a reason why it is only 2 cores or can we increase that say on a 6 core sysstem?
As always thank you for the info.

1) plan_class
2) You can make it any number you wish, but it's probably better to use only physical cores and not logical cores. I.e., don't use hyperthreads.

1) <plan_class> starts the line </plan_class> ends it. pla_class was a typo.
2) change the 2s to the number of cores you want to use.
To use 6 cores:
<cmdline>-nt 6</cmdline>
<avg_ncpus>6</avg_ncpus>
Edit: I need to start keeping the thread open in another window and refresh just before posting | |

Does that work for all genefer cpu apps? Not just 21? | |

For now, only 21. | |

You have only app_version, try this:
<app>
<name>genefer</name>
<fraction_done_exact/>
</app>
<app_version>
<app_name>genefer</app_name>
<plan_class>cpuGFN21</plan_class>

Two questions:
1) Is it working as intended? If it is, ignore that message.
2) If it's not working, which of your computers is this happening on?
Some of your computers are running a newer version of BOINC than I am, and some are running an older version. It's possible that the latest BOINC versions require an <app> section, which previous versions definitely don't.

<app_version>

<plan_class>cpuGFN21</plan_class>

</app_version>
Although it's possible the lastest BOINC clients need <app>, none of the older versions do. Needless pain in the posterior if 7.12.x needs it.
<fraction done exact> is never needed at PrimeGrid. We set that flag at the server on every task.
BOINC put that mechanism into BOINC at my request. ;)

Think that fixed it but it's hard to tell. I don't see a way to clear previous BOINC notifications so I can't tell if its the old notification or just re-daiplaying the same error. I'll wait until I get a new notification about something else and verify.
Thanks!
EDIT: Nope looks like getting the same error

Have you ever downloaded a GFN-21 task on that machine? If not, everything is working as intended and the message will disappear once you do that.

I use BOINC client version 7.6.33. I don't get accurate run times unless I use <fraction done exact>. Without<fraction done exact>, BOINC MANAGER projects remaining run times 2-3 higher than the actual time required.

It appears that many of the genefer CPU apps were updated at the same time. Can all of those be run MT too?
Sorry if this was already asked/answered. It is a very LONG discussion.

The apps were kept in sync across all of the sub-projects, but the performance improvement and multithreading only works for n=21.

Any reason I'm getting one GFN21 WU running 36 CPU's when my config looks like this?
<app>
<name>genefer</name>
<fraction_done_exact/>
<max_concurrent>2</max_concurrent>
</app>
<app_version>
<app_name>genefer</app_name>
<cmdline>-nt 18</cmdline>
<avg_ncpus>2</avg_ncpus>
<plan_class>cpuGFN21</plan_class>
</app_version>
Should be running two 18 CPU's right? | |

The only place that -nt 36 can come from is app_config.xml. You had -nt 36 in there at one point, right? When you changed it to -nt 18, did you tell BOINC to reread the config files? And, if necessary, restart the task? (That probably requires restarting BOINC too, in most cases.)

Should it be -t and not -nt? Is genefer 21 different than the other llr apps? If it's being passed to the cmd line as Mike said, it's coming from somewhere.... I'm just not sure about that -nt, I haven't run GFN21 on CPU with multithreading. | |

Genefer and LLR are two different programs.
