cuda - Number of cores on NVIDIA K20 GPU in Mathematica -


i using nvidia k20 gpu in mathematica. whitepaper k20 states following specs:

  1. 2496 single-precision cores (192 per multiprocessor x 13 multiprocessors)
  2. 832 double-precision cores (64 per multiprocessor x 13 multiprocessors)
  3. 416 special function units (32 per multiprocessor x 13 multiprocessors)

however, when launch mathematica , @ specs of gpu after loading opencl or cuda, says have 416 cores (i have attached screenshot of mathematica commands , reported specs). somehow related number of double-precision cores or special function units? mathematica reports these specs before tell kind of code write (e.g. double precision, transcendental functions).enter image description here

it more mathematica not yet know kepler architecture yet, , translates multiprocessor count core count incorrectly.

since "cores" marketing invention anyway, can safely ignore number. mathematica still use entire gpu (although kepler-aware version might still bring speedup through other optimizations).

ios - iPhone/iPad different view orientations in different views , and apple approval process -

i force app's home screen portrait , other views landscape. apple rejects app if this? if not , how force first screen launch in portrait mode? , force other screens launch in landscape. this not duplicate question search every possible answer in website. i force app's home screen portrait , other views landscape. apple rejects app if this? no apple not reject app this. have lot of apps doesn't support orientation. forcing on 1 screen won't cause app reject. if not , how force first screen launch in portrait mode? , force other screens launch in landscape. can on write : -(nsuinteger)supportedinterfaceorientations; function.

java Extracting Zip file -

i'm looking way extract zip file. far have tried java.util.zip , org.apache.commons.compress, both gave corrupted output. basically, input zip file contain 1 single .doc file. java.util.zip: output corrupted. org.apache.commons.compress: output blank file, 2 mb size. so far commercial software winrar work perfectly. there java library make use of this? this method using java.util library: public void extractzipnative(file filezip) { zipinputstream zis; stringbuilder sb; try { zis = new zipinputstream(new fileinputstream(filezip)); zipentry ze = zis.getnextentry(); byte[] buffer = new byte[(int) ze.getsize()]; fileoutputstream fos = new fileoutputstream(this.tempfolderpath+ze.getname()); int len; while ((len=zis.read(buffer))>0) { fos.write(buffer); } fos.flush(); fos.close(); } catch (filenotfoundexception e) { // todo auto-generated catch block ...

C# WinForm - loading screen -

i ask how make loading screen (just picture or something) appears while program being loaded, , disappears when program has finished loading. in fancier versions, have seen process bar (%) displayed. how can have that, , how calculate % show on it? i know there form_load() event, not see form_loaded() event, or % property / attribute anywhere. all need create 1 form splash screen , show before main start showing landing page , close splash once landing page loaded. class splashform { //delegate cross thread call close private delegate void closedelegate(); //the type of form displayed splash screen. private static splashform splashform; static public void showsplashscreen() { // make sure launched once. if (splashform != null) return; thread thread = new thread(new threadstart(splashform.showform)); thread.isbackground = true; thread.setapartmentstate(apartmentstate.sta); thread....
