hello. i was wondering if their was a way to set the maximun number of CPU's per task. i get an automatic 8 cpu task load. some are single cpu's but most are 8. i was messing around with my bios for un related reasons and turned off my hyperthreading and then i got 4 cpu tasks... i kinda like the 4. is there a way to get no more then 4 cpu task loads? singles are fine too.

even two per task, that'd be nice. who runs the servers?

You can use app_config.xml, see Project-level configuration.

This should work:

<app_config>
<app_version>
<app_name>milkyway_nbody</app_name>
<plan_class>mt</plan_class>
<avg_ncpus>4.000000</avg_ncpus>
<cmdline>--nthreads 4</cmdline>
</app_version>
</app_config>

I experienced the same decrease of max. CPU tasks. It began on January 16 after changing server otions were reported.
It is frustrating and annoying! My newer computer (bought in January 2018) is equipped with an Intel Core i9-7900X with 20 processors. I only get a max. of 20-30 tasks at once. Today I ran out of CPU tasks at around noon because servers were down from 10:30am until 6:30pm (now it is nearly 7:30pm).
Due to increasing problems with the M@H servers I already stopped crunching GPU tasks in autuum 2018. Servers were off in the past weeks on a daily base. That is an absolute No-No!

We all do crunching voluntarily for personal reason(s). But how will M@H recruit new volunteers when servers are regularly down?


An app_config.xml may be useful...Yes! But only if the servers are online and you can get tasks to work with!


On my newer computer I already stopped crunching Milkyway@Home. I will use my processores for other projects...
Sorry, Milkyway@Home!

There are still several hundreds of finished workunits hanging around at Mr. Pen-Dings pub...

You may see my computers on my profile.
