what is a von neumann bottleneck?
479857
The term "von Neumann architecture" has evolved to mean any stored-program computer in which an instruction fetch and a data operation cannot occur at the same time because they share a common bus. This is referred to as the von Neumann bottleneck and often limits the performance of the system.

A CPU that offers multiple cores or hyper-threading may perform significantly better than a single-core CPU of the same speed that doesn't feature hyper-threading. And PCs with multiple CPUs can have an even bigger advantage.

14.8 Summary. The Von Neumann architecture consists of a single, shared memory for programs and data, a single bus for memory access, an arithmetic unit, and a program control unit.

0. VMSTAT r (runqueue) The runqueue value shows the number of tasks executing and waiting for CPU resources. When this number exceeds the number of CPUs on the server, a CPU bottleneck exists, and some tasks are waiting for execution. I believe in AIX this would be a number equal to or less than lcpu.

The input lag on vsync is extremely noticeable. I varies but it's vastly more acceptable than screen-tear. I nearly always use adaptive V-Sync and it does it's job reasonably well most of the time (although sometimes you have to fiddle with settings some more).

Pipelining introduces latches on the data path thus reducing the critical path. This allows higher clock frequencies or sampling rates to be used in the circuit. In parallel processing logic units are duplicated and multiple outputs are computed in parallel.

CPUs are typically optimized to work with one type of memory or the other, and you cannot mix them on a motherboard since they require completely different sockets. Furthermore, even within the same family, RAM modules typically get faster and your old RAM may not be able to keep up with a new CPU.

Harvard vs Princeton The Von Neumann (a.k.a. Princeton) architecture developed for the ENIAC uses the same memory and data paths for both program and data storage. The Harvard architecture characterized by the Harvard Mark 1 used physically separate memory and data paths for program and memory.

Von Neumann architecture is the design upon which many general purpose computers are based. The key elements of Von Neumann architecture are: data and instructions are both stored as binary . data and instructions are both stored in main memory.

A virtual processor core (VPC) is a unit of measurement that is used to determine the licensing cost of IBM products. ... A vCPU is a virtual core that is assigned to a virtual machine or a physical processor core if the server is not partitioned for virtual machines.

Transcript: More virtual CPUs are assigned to the virtual machine than the number of physical CPUs on the host system. This is likely to degrade performance of your virtual machine.

A bottleneck is a point of congestion in a production system (such as an assembly line or a computer network) that occurs when workloads arrive too quickly for the production process to handle. The inefficiencies brought about by the bottleneck often creates delays and higher production costs.

Hyper-threading is specific to Intel, and AMD have an equivalent in the form of SMT. Personally, I find both technologies rather gimmicky and no substitute for a true quad, hexa or octa-core CPU. Yes, they offer an improvement, but it's not much in everyday use.
