Core running in safe mode?!

I've noticed this before; after a system crash (last night we had a power-outage due to a storm) the F@H client runs extremely slow. This morning I restarted the fileserver in my sig and when I got home noticed it took approx. 1hr and 5mins to complete a step! (project3040) WTF!? After a shutdown and normal Boot of the system it is now taking about 28mins per step!? Is the client running in some kind of safe mode after an improper core shutdown or what?

First it does this:

Folding@Home Client Shutdown.

And after a reboot it does this;

See the time difference per step?! I notice the line "Extra SSE boost OK." is missing after the first start, could that be it?!

Yes, it is:
06:14:17] - Working with standard loops on this execution.
[06:14:17] - Previous termination of core was improper.

That's why you want "forceasm" in your initialization string for the FAH client.

Standard loops = no SSE.

That's the first time I've ever heard about that forceasm thingy. How and where do I put that? My rig could've done twice the work today, grrrr!

it is a command line switch -forceasm. If running from the desktop/shortcut add it to the end of the target string (separated by a blank) Running as a service you need to add it to the parms in the registry.

I always put it on every new instance i setup along with the -verbosity 9 switch.

Restarting the client again also fixes the problem, and the client will run at full speed again. If power outages are common, then adding -forceasm is a good idea.

And if you hadn't heard about this switch, then may be you also missed out on the fah WIKI. It has good info as well. For instance... http://fahwiki.net/index.php/How_do_I_add_flags_when_running_the_console_in_service_mode?

Hey 7im, what's the status over on FC.org?

pete,

probably a typo, but its -forceasm

Yes, the Folding-Community Support forum is down temporarily. Please be patient while the ISP hosting the site works to correct the problem.

You can watch the Stanford News page for updates. http://folding.stanford.edu/news.html

Or just post here in your own forum. I'll be dropping by a little more frequently until the support site is back up.

Thanks.

Thanks 7im.
Hey, speaking of the -forceasm argument, didn't someone mention that this flag is irrelevant on a Linux box?

thanks W... yes just another one of my typos

and edited it

IIRC, that's half right. Don't need -forceasm on a Linux box running the SMP client. -forceasm is hard coded to on in the SMP beta.

Thanks for the clarification, 7im. It's better to be half right than uh, howze that go...oh yea, having a glass that's half empty!
