FAH doesn't specify which CPU it will use, only how much ... it's up to the scheduler in the OS to pick the available CPU. From the perspective of the program, 100% of 1 CPU is the same as 50% of two CPUs. or 33% of three CPUs. right, but seems to be different on a kvm based cluster... Few hours ag...

Consider a single 4-cpu VM, who might be trying to run something concurrently OTHER than FAH? Looking at that single machine, OS makes the decisions for the entire machine. The owner might want to do some browsing so he starts up that task which has nothing to do with FAH. That foreground task gets...

Actually for slower systems that wouldn't complete a WU within timeout unless left of 24/7 (and this does happen in GPU land) the QRB does in effect encourage 24/7 hence why I mentioned it ... Even with a 4hr WU there is an encouragement from the QRB to fold for at least 4hrs after the WU is downlo...

Hi all, yesterday I started a new VM and spent a couple of time to complete the found issues analysis: I collected some information on the "power-control" issue and some other about other issues found on OS/Package control. I have also many log files (available on demand) but I'm going to ...

May you explain me a little bit in deep this concept?

Thanks in advance.

One thing to consider depending upon how broad your thoughts of "dynamic" are ... especially if you have any thoughts as to dynamically resizing (from a vCPU perspective) VMs during the course of folding a WU ... and that is that whilst it is possible to reduce the number of threads/cores...

A few thoughts. With a 4 CPUs system, the overhead will probably always result in near 100% utilization. I don't have experience with so few threads, my smaller processor is a 4C/8T running on 6 threads (at 100%). In fact, each time I use about 2/3 to 3/4 of the available threads, the overall utili...

From the perspective of the program, 100% of 1 CPU is the same as 50% of two CPUs. or 33% of three CPUs. I think you misuderstand the concept of power=light FAH has absolutely ...

...When the new WU is arrived started using 4 cpu at 100% but I lost the control of power from FAHControl: now if the value is set to light, medium of full the changes are not applied and all the cpu are always at 100%. This mean that the power control is available only when i use -1 an CPU (and I ...

If you install the software into a VM without an internet connection it will not connect and so no id is created ... if that VM is cloned and the individual VMs stood up from it are allowed to connect to the internet themselves this resolves id issue (I think - someone more technical than me will n...
