Re: [Condor-users] Windows 2000 Server + Condor

[Andrew Cunningham <andrewc@xxxxxxx>]

Hi Matt,
	It turned out that the problem seemed to be due to having 'hyper- 
threading' on with a Pentium 4 CPU on the W2KServer - so that Condor  
saw two vm's. vm1 would execute , but vm2 would fail to execute with  
an error. Turning off HT solved the problems.
