i'm working on application heavy number crunching. intended run on single computer. recently, we've started looking @ multithreading speed calculations. of algorithms can made run parallel without effort, , use fixed thread pool run each of sub tasks. what wondering is: how number of threads (the size of pool), typically specified these kinds of algorithms? suspect typically done using either configuration file, or commandline parameter, haven't seen examples that, wondering if there better ways. related this: relevant specify number of threads? thinking setting pool size number of assignable cores run fastest, thread-contention processing power in case of on assignment relevant performance? eg: setting 20 max threads on 4 core machine worse setting 4 max threads? edit: application intended sale, have no idea computers run on. i'm looking general guidelines, , best practices. a rule of thumb use number_of_cores + 1 threads (certain parallel build sy...

what happening tcp connection after end of http session? example, after loading static webpage webserver thanks a http session refers server keeping association specific user , potentially of length (using, instance, cookies association tokens). a http session therefore contains multiple tcp sessions. non persistent http connections, every request has own tcp session (and closed after). persistent http connections on other hand, multiple http resources fetched wihtin tcp session , either side close upon reached timeout threshold on either side. wikipedia article on persistent http connections (keep-alive: true)

this question has answer here: using iphone/objective c cgfloats: 0.1 okay, or should 0.1f? 1 answer what's different between: cgfloat gray[4] = {0.9f, 0.9f, 0.9f, 1.0f}; and cgfloat gray[4] = {0.9, 0.9, 0.9, 1.0}; ? i think same don't know sure. i believe indicating number float (i.e. single-precision floating point) opposed double (double-precision floating point),
