Hrm, but all the guides suggest staying 3.0.0, guess I'll try upgrading to 3.1.4.

Some guides just say to use 3.0.0 without providing a reason, while others state that later versions have difficulties recognizing more than 4 cores.

Just got back so I'm installing 3.1.4 and trying the Linux FAH image.

Edit -

Just tried 3.1.4 and got the option to select 8 CPU but got an error about it only liking 4.

this might be better solved in the f@h section, as this seems to be more of a vmware problem than a linux problem...my only suggestion would be to forgo vmware and go for a straight install to harddrive...but thats probably not an option huh?

Are you really doing something that intensive on a VM anyway?

If you were truly in need of the extra thread handling processing power you'd be much better off running your application in a non-virtualized environment..

Hrm. I'm trying to run F@H in linux since it has been reported by several members on this forum to yield more efficient production. With equivalent clocks, people are getting TPF of 6-7 minutes less, which is pretty significant.

I thought was doing wrong on my end in terms of missing certain libraries or something, which is why I asked in the Linux section. I'll try asking in F@H thanks!

Any benefit of running on top of linux will be lost within VMware overhead.

Not sure about player or workstation specifically, but the figures for ESX server are a loss of 8-10% versus a bare hardware configuration. For integer and floating point specific workloads the difference is > 10%

Haha! Unfortunately, when VMware doesn't like the core #, it won't let me boot. The system is for me to attempt to fold bigadv more efficiently. I've been cutting pretty close to the deadline as I've only really let it fold 18-19 hours a day instead of the intended 24 ; ;
