In a ConcurrentHashMap, for instance, several threads can acquire locks on different map segments, so multiple threads can access the Map at the same time. 例如,在ConcurrentHashMap 中,多个线程可以获取不同映射段上的锁,所以多个线程可以同时访问这个map Concurrent collections aremuch more performant th...
However, actor functions are reentrant, which is a computer science term that means one task can start while another one is still running. I know that sounds like it breaks the rules I laid out above, but it's one of the subtle nuances of actors you'll need to understand in ...
The smallest DoubleSpace allocation unit is the sector, which is 512 bytes on most systems. This finer granularity is possible because DoubleSpace maintains its own disk allocation data structures within the CVF that map FAT clusters to DoubleSpace sectors. As a consequence, DoubleSpace minimizes c...
5 Good results have still been reported when the rotor/focal source happens to lie at a site where the basket makes contact.6 In these cases, many electrodes away from this site may not be in contact, and basket repositioning is needed to map the entire chamber. ...

The CPU uses the Interrupt Descriptor Table (IDT) to map the interrupt vectors to functions (interrupt handlers) which are supplied by the kernel. When an interrupt arrives, the CPU indexes the IDT with the interrupt vector and runs the appropriate handler. Thus, the kernel is entered. (On ...

Chromatin in eukaryotic cells is a negatively charged long polymer consisting of DNA, histones, and various associated proteins. With its highly charged and heterogeneous nature, chromatin structure varies greatly depending on various factors (e.g. chemical modifications and protein enrichment) and the ...
