cuda - Does multiProcessorCount gives the number of streaming multiprocessors? -


i hardly understand value given multiprocessorcount property represent, due fact experience difficulties in grasping cuda architecture.

i'm sorry if of following statements appear naive. understood far, here hardware "layers":

  • a cuda processor grid of building blocks.
  • a building block composed of 2 or more streaming multiprocessors.
  • a streaming multiprocessor composed of many streaming processors, called core.
  • a streaming processor "massively" threaded, meaning implements many hardware managed threads. 1 streaming processor, 1 core, can compute 1 thread @ time, has many "hardware threads" can load data while waiting turn computed sp.

on software side:

  • a block composed of threads, , executed streaming multiprocessor
  • if 1 launched more blocks number of streaming multiprocessors on card, guess blocks wait in sort of queue, executed.
  • software threads distributed streaming processors, distribute them hardware threads. , similar previous case, if 1 launched more threads streaming processors can handle hardware threads, software threads wait in queue.

in both cases, max number of threads, , blocks, allowed launch, independent number of streaming multiprocessors, streaming processors, , hardware threads of each streaming processor, exist on card. notions software!

am @ least close reality?

with being said, multiprocessorcount property gives? on 610m, says have 1 multiprocessor... mean have 1 streaming multiprocessor? have building block composed of 1 streaming multiprocessor? seems impossible me. , mean can execute 1 block @ time! besides, when specifications of card says have 48 cuda cores, talking streaming processors?

perhaps this answer help. it's little out of date since refers old architectures, principles same.

it entirely possible gpu consist of single sm (streaming multiprocessor), if mobile gpu. single sm, composed of multiple cuda cores, can accommodate multiple thread blocks (up 16 on latest kepler-generation gpus).

in case, 610m gpu has 1 streaming multiprocessor (sm), composed of 48 cuda cores (aka streaming processors, sps).

SPSS keyboard combination alters encoding -

my question not have programming practical issue on spss. accident keyword combination cannot remember because did not intend press changed encoding in spss , text in data in different language english shown small boxes. nevertheless, when kind of analysis performed different language text shown in output. does know reason? tried change encoding did not produce result. first, @ edit > options , see whether setting unicode or locale. might fix it. if have text in multiple languages, want unicode. otherwise, may have specific locale set wrong. can change set locale, need know locale want use.

Add new record to the table by click on the button in Microsoft Access -

in ms access form want implement separate button, adds new record table. in order added button , attached button event: private sub btnaddrec_click() refresh codecontextobject on error resume next docmd.gotorecord , , acnewrec if err.number <> 0 btnaddrec.enabled = false end if end end sub everything ok when open window , click btnaddrec button, problem when first of perform navigation through existed records , after click on button. got runtime error: 2105: «you can't go specified record. may @ end of recordset» . how solve issue, need have ability add new record on click on specific button, no matter, have walked or not walked through records before. thanks. i created simple form field call description (and autonumber) , created button code follows click event. filled number of records , navigated through them, clicked addnewrec button. form navigated new record without issues. able click addnewrec button directly after
