i convert 4 packed 64 bit integers 4 packed 64 bit floats using avx. i've tried like: int_64t *ls = (int64_t *) _mm_malloc(256, 32); ls[0] = a; //... ls[3] = d; __mm256i packed = _mm256_load_si256((__m256i const *)ls); which display in debugger: (gdb) print packed $4 = {1234, 5678, 9012, 3456} okay far, cast/conversion operation can find _mm256i_castsi256_pd, doesn't me want: __m256d pd = _mm256_castsi256_pd(packed); (gdb) print pd $5 = {6.0967700696809824e-321, 2.8053047370865979e-320, 4.4525196003213139e-320, 1.7074908720273481e-320} what i'd see is: (gdb) print pd $5 = {1234.0, 5678.0, 9012.0, 3456.0} all of cast intrinsics perform bitwise cast, why you're not seeing meaningful results that. a vector conversion (the cvt intrinsics) between 64-bit integer , 64-bit float not exist.

how can ensure ef generates same id same occurence of object? e.g. if have class like: class foo{ icollection<bar> bar1; icollection<bar> bar2; } if create new entity foo , add single instance of bar (no id set) both bar1 , bar2 - use same id both or create new 1 each time? e.g.: var bar = new bar(); var foo = new foo{ bar1 = new list<bar>(){ bar }; bar2 = new list<bar>(){ bar }; } context.savechanges(); will bar1 , bar2 contain same record bar same id? update: if have 2 instances same respect equals , hash code? var first = new bar(); var second = new bar(); /// first.equals(second ) var foo = new foo{ bar1 = new list<bar>(){ first }; bar2 = new list<bar>(){ second }; } or ef not check equals? yes, entity framework create 1 record foo , 1 record bar in database. since both lists contain same instance of bar respective database entries point same record.

i have piece of canvas animation exhibiting weird characteristics: http://jsbin.com/olasol/2/edit i'm on latest version of chrome. i'm using chrome's inbuilt fps monitor (you can activate going about:flags ). have marked line in javascript section think potential culprit: fallingctx.clear(); this line nothing special. calls function in-turn calls clearrect() . the "weird" things notice are: the clear(); function causes noticeable fps drop on laptop (core 2 duo), not on desktop (i5 2500k). removing line alone sufficient produce 60fps on laptop well. expected, canvas doesn't clear after each frame, still, produces stable 60fps. the fps drop happens when chrome window on larger side! when shrink window , reload, doesn't happen! (is more expensive clear larger rectangle?). i tried replacing clear() drawimage() of full white jpeg cover canvas. javascript able 200 drawimage() executions each cycle smaller image particles (evident second p...
