Typically virtualisation is used in a data centre to slice data centre compute resource into Virtual machines, and potentially to present several logical processors by mapping these onto a single physical processor.
To obtain the service time by means of the discrete mode of the SIMPRO, we measured the number of cycles by running the proxy on a PISA architecture, available on the Simplescalar toolset, which according to [28] has several similarities with the physical processor we used in these experiments.
After defining their power model, the authors proposed a power aware framework including the following five steps: Requesting a VM, generating the RT-VM from real-time applications, requesting a real-time VM, mapping the physical processors, and finally, executing the real-time applications.
The servers include multiprocessor machines (4 16 physical processors) under the AIX operating system and a cluster of single processor machines under the Linux system.
With VSA, one can easily obtain the scheduling data associated with virtual processors (i.e., VCPUs) and physical processors (i.e., PCPUs), and further conduct the scheduling analysis for a group of interacting VCPUs running in the same domain.
However, although four virtual processors apparently run as four physical processors, the target performance cannot be as high because only some processor components are replicated while others must be shared between processes or threads.
In November 2012 Folding@home updated its accounting of FLOPS, especially for GPUs, and now reports the number of active processor cores as well as physical processors.
The MCMC simulation of a single chain took 6 - 6.5 hours on a computer with a 3 GHz dual core processor and a physical memory of 2 GB.
You will also probably need a calculator application and either a word processor document or a physical notepad for taking notes on curvatures and radii.
