Re: Rejecting a4 core WUs

Thats unfortunate. Is this something that is on the roadmap? If it isn't, I've read briefly about the existence of some type of plugin support in FAHClient on the main fah website and that the forum would be the place to ask about this. The change I'm looking for is pretty basic so if such a thing e...

Re: Rejecting a4 core WUs

@JimboPalmer: Some more CFD oriented workloads take a few days to complete, but some other finance modelling takes on the order of months to complete a single run, hence why a reboot wont be feasible this winter. Since these machines are silent and have a reasonable TDP when combined I actually use ...

A bit of a mish-mash as its what I had on hand and was very very cheap (average about £1 per core, £0.80 per GB of memory all in. Couldnt really go faste...

Re: Rejecting a4 core WUs

I've read about the previous problems with core 0xa4 and vsyscalls, and I have no doubt that its an easy enough fix for most cases to use emulated mode in the kernel options but in this case, thats an impractical solution. If you want proof of this being the typical case I've read about multiple tim...

Rejecting a4 core WUs

Apologies if this is in the wrong place. I am aware of this being solved by enabling vsyscall. In this instance, it is not practical to recompile and reboot. Is there any way to either: [*] solve the infinite loop that results from a segfault in trying to run a4 core on a system without sysvcall? [*...
