Module documentation This module is rated as beta , and is ready for widespread use. It is still new and should be used with some caution to ensure the results are as expected.
In early processors, the TSC was a cycle counter, incrementing by 1 for each clock cycle (which could cause its rate to vary on processors that could change clock speed at runtime) – in later processors, it increments at a fixed rate that doesn't necessarily match the CPU clock speed. [n] Usually 3 [o] Intel Pentium, AMD K5, Cyrix 6x86MX ...
The process of verifying and enforcing the constraints of types—type checking—may occur at compile time (a static check) or at run-time (a dynamic check). If a language specification requires its typing rules strongly, more or less allowing only those automatic type conversions that do not lose information, one can refer to the process as strongly typed; if not, as weakly typed.
Such a system implemented with a single backup is known as single point tolerant and represents the vast majority of fault-tolerant systems. In such systems the mean time between failures should be long enough for the operators to have sufficient time to fix the broken devices ( mean time to repair ) before the backup also fails.
Runtime metrics can help Information gathered during a test run can be used in profile-guided optimization. Information gathered at runtime, ideally with minimal overhead, can be used by a JIT compiler to dynamically improve optimization. Strength reduction Replace complex, difficult, or expensive operations with simpler ones.
A single point of failure (SPOF) is a part of a system that, if it fails, will stop the entire system from working. [1] SPOFs are undesirable in any system with a goal of high availability or reliability , be it a business practice, software application, or other industrial system.
