i have computation has structure of binary tree, @ each node bunch of highly vectorized functions take output of previous branches produce new branch(es) (nodes on same level independent). since functions vectorized, run both on cpu or gpu, latter naturally giving substantially faster execution. i have access 4-gpu 2-cpu workstation run code on , use optimally can. understand how use parfor on gpus or on cpus' cores only, reasonably distribute workload between gpus , cpu, since gpu execution leaves many cpu cores @ idle, , though slower gpus, still fast enough have noticeable impact on total execution time. (q1) since functions in each node vectorized, reasonable run independent nodes in 1-node-per-core mode? or strictly depend on particular case? there "rule of thumb" such dilemmas? (q2) assuming in (q1) simultaneous execution of 1 node per core suboptimal, there way assign several cpu cores 1 worker? (q3) there way distribute parfor workers between gpu...

i'm not sure how phrase question i'll give example of i'm looking do. i have function gets next byte fifo. void fifoget(uint8_t * byte) { *byte = somefunction(); } i'm making function flush fifo void fifoflush(void) { uint8_t i; uint8_t discardbyte; (i=0; i<fifolength; i++) { fifoget(&discardbyte); } } what i'm wondering, since don't need discardbyte , can around allocating memory , pass void pointer fifoget()? something like void fifoflush(void) { uint8_t i; (i=0; i<fifolength; i++) { fifoget(&void); } } no, void approach cause behaviour of program undefined you'll dereferencing pointer unknown memory. your using discardbyte best thing do.

i new mobile development , interested hybrid apps , of course intel xdk. when reading intel xdk's documentations faced "runtime" word. what mean of phrase , it's mean when saying crosswalk html5 runtime, ... in blog post . apologize me if asking 1 of stackoverflow's stupid questions. "runtime" refers time program runs , opposed other times in programs life cycle compile time . software typically written, compiled, deployed or installed, run. these different phases referred "compile time", "install time" , "runtime". e.g. "at compile time, compiler ..." . " a runtime" software package necessary at, well, runtime. e.g. library, interpreter, virtual machine or other such supporting packages. crosswalk system takes in html 5 "apps" (including html, javascript etc.) and, well, makes them work. executes them. runs them. it's browser engine, not packaged browser, system...

i know if that's possible cast dynamic other class (partially or totally) for example, code breaks : class test { public function new() {} public var id: string; } class main { public static function main() { var x:dynamic = jsonparser.parse("{\"id\":\"sdfkjsdflk\"}"); var t:test = cast(x, test); } } with following message class cast error however, "test" class has "id" field dynamic object. (that's example, use case more complexe ^^) so, don't understand how object dynamic one. this isn't casting dynamic class instance may accomplish same thing: create empty instance of class type.createemptyinstance set of fields dynamic object on new class instance using reflect example: import haxe.json; class test { public function new() {} public var id: string; } class main { public static function main() { var x:dynamic = json.parse(...

i have read through many questions on over custom deleter shared_ptr , unique_ptr , , difference between two. but, still haven't found clear answer question: how can 1 best go creating type acts shared_ptr custom deleter, similar how unique_ptr has deleter part of type definition? for unique_ptr usage, use deleter class, handles deletion of individual types (limiting 2 types, brevity): struct sdl_deleter { void operator()( sdl_surface* ptr ) { if (ptr) sdl_freesurface( ptr );} void operator()( sdl_rwops* ptr ) { if (ptr) sdl_rwclose( ptr );} }; using surfaceptr = std::unique_ptr<sdl_surface, sdl_deleter>; using rwopsptr = std::unique_ptr<sdl_rwops, sdl_deleter>; which can used like surfaceptr surface(img_load("image.png")); and call sdl_freesurface upon destruction. this fine , well. however, how 1 go achieving same shared_ptr ? type defined as template< class t > class shared_ptr; and...
