Hi, Can anyone shed some light on this: My PC's are on a separate power circuit. Each PC has its own UPS. I have an old Honda generator. When the power goes out, I fire up the generator. However, the UPS's still run on battery. If I connect the PC directly to the socket and bypass the UPS, the PC works. I was told by a UPS supplier, that the power output from the generator was

Hi, I'm the original poster on the subject. Thanks for all the replies. A few more points. The generator outputs 7kw @ 220V. The total PC's supplied is about 9. I estimate power consumption to be 9 x 300w=2700w 4 halogens @ 400w each=1600w 10 Compact Flourescents @ 11w =110w Therefore total power=4410w Which leaves me with spare capacity of about 2590w (in theory). I think its the halogen lamps that is helping "smooth" out the power. Previously, when I ran the generator, I did not have the halogen lamps on, and the UPS failed to recharge. Re...

There's the llvm-testresults list, but I find it less than fully useful because it's not immediately obvious from scanning message subjects if there's been a test
