The term can also refer to the condition a computer running such a workload is in, in which its processor utilization is high, perhaps at 100% usage for many seconds or minutes, and interrupts generated by peripherals may be processed slowly or be indefinitely delayed.
Thread scheduling is also a major problem in multithreading. Merging data from two processes can often incur significantly higher costs compared to processing the same data on a single thread, potentially by two or more orders of magnitude due to overheads such as inter-process communication and synchronization.

In Windows 2000 and Windows NT 4.0, these same displays are labeled "Mem usage" but again actually show the commit charge and commit limit. Similar displays in the Task Manager of Windows Vista and later have been changed to reflect usage of physical memory.
Later versions of the system removed the controller and memory card slots, effectively removing this feature. In telecommunications and computing , backward compatibility (or backwards compatibility ) is a property of an operating system , software, real-world product, or technology that allows for interoperability with an older legacy system ...
Amdahl's law applies only to the cases where the problem size is fixed. In practice, as more computing resources become available, they tend to get used on larger problems (larger datasets), and the time spent in the parallelizable part often grows much faster than the inherently serial work.
Issues with episodic memory — memory for events in time or if a person doesn’t remember going shopping, for example — can be a sign of a progressive disorder, but not always.
"A problem in computer science is considered unsolved when an expert in the field (i.e, a computer scientist) considers it unsolved or when several experts in the field disagree about a solution to a problem" seems unnecessary, since most of the problems on the list require exact, non-subjective solutions.
Java memory use is much higher than C++'s memory use because: There is an overhead of 8 bytes for each object and 12 bytes for each array [ 61 ] in Java. If the size of an object is not a multiple of 8 bytes, it is rounded up to next multiple of 8.
