What is Virtual core and how does it different from Physical core?

A virtual core is a CPU with a separation between two areas of the processor. Virtual cores take over some of the computer’s processing without interfering with the other area. A virtual CPU (vCPU) also known as a virtual processor. It is not present in the CPU, but pretends to be present.

Virtual core processing provides automatic detection and visualization of basic characteristics such as separation fractions, dive angles, rolling frequency, intensity, and more for quantitative and consistent data interpretation across all wells. State-of-the-art machine learning algorithms enable automated and semi-automated methods to classify rocks or similar events into entire cores. Virtual Core incorporates full-core CT, photos, and processed feature detection views (including microscopic-level data) with good petrophysical log data into a comprehensive, integrated visualization and analysis environment.

Virtual Core Features

• Data cleansing

and

• processing Integrated viewer for well logs, images, and volumes

• Easy navigation from hundreds of feet of core to millimeter resolution capabilities

• Machine learning with advanced detection algorithms

Let’s find out how it differs from the physical core.

• Hyper-Threading technology creates two virtual processing cores for each physical core present in a CPU.

The physical core

• powers the virtual cores, which then share responsibility for task processing

.

• Each virtual core is identical to the other, and while neither is as powerful as the physical core, together they far outweigh the power of the physical core when Hyper-Threading is not enabled. A physical

core is

• what it is called in the name, a core that is physically on the chip. A logical core is a way they are treated that causes them to be used as two cores, meaning that an AMD 8350 has 4 physical cores and 4 logical cores, while an i7 4760k has 4 physical cores and 0 logical cores.

• The i7 quad core is 4 physical cores and 8 logical cores. A logical core is essentially how many threads it can process at the same time. A thread is a sequence of instructions. So, for this i7, it can process 8 threads at the same time that ht allows 2 threads per physical core. An octa-core like the fx 8350 has 8 physical cores and 8 logical cores as it can do 8 threads. You can have many more threads running, but the CPU will only process so many at a time.

A physical core

• is what it sounds like: an actual physical processor core in your CPU. Each physical core has its own circuit and its own L1 (and usually L2) cache can read and execute separate instructions (for the most part) from the other physical cores on the chip. And on the other hand, a logical core is more of a programming abstraction than an actual physical entity. A simple definition of a logical core is that it is a processing unit that is capable of running its own thread in parallel with other logical cores. In fact, you could say that a logical core is the same as a thread.

• You can have multiple logical cores per physical core. However, logical cores share resources with other logical cores operating on the same physical core, so having more logical cores will not necessarily give you the same performance boost as having more physical cores.

The maximum number of virtual

• CPUs you can allocate to a virtual machine is the same as the number of physical cores on the host. Each vCPU represents a virtual machine execution thread, so it doesn’t really make sense to create more threads for the same virtual machine than the number of threads the host can run simultaneously. However, the total number of vCPUs for all virtual machines on a host can (I would argue it should) exceed the number of physical cores.

The number of

• physical CPU cores is important for optimizing the database and SAP instance, not the number of CPUs or any virtual CPUs (hyper-thread technology). If it is a 4-way, 4-core CPU host, then there are 16 physical CPUs recognized and running for applications.
