P8828

Postby rickoic » Fri Feb 13, 2015 4:28 pm

Just happened to notice that P8828 scales down to 32 cores when I have allocated 40 cores for it.

Anyone else having this occur.

Is this a LC (large core, formerly BA) project?

8828 is one of the large SMP projects that have been around for a while and use the A3 core. Bigadv folders are getting them until the large core projects for A5 are available if they are not participating in the beta testing of 8106 to 8108 or a LC WU is not available when a new WU is requested.

But why does it drop the core count down to 32?

It is probably configured for a maximum of 32 cores but I don't know how to tell. Some projects become unstable if too many cores are used.

Per didn't happen to mention a core min and max when these were released.

P8108 is limited to 32 cores also, apparently

Had it set for 41 cores and it mapped 41 to 32 by passing 40.

Looks like it likes 48, but if you drop it below that it drops all the way to 32.

Just for clarity, everyone knows that P8828 is an a3 SMP project, while P8108 is an a5 LC SMP project, right? ;)
