Cuda thread linear indexing -

-

I need to index my thread in such a way that I'm sure 32 of them are taunts of the same, That is, the linear index follows how warps internally is created. In other words, there are linear indexes that are used to create Warpace C such as Fortune. To illustrate this, consider a block of size 2x5 thread, I can make a linear indicator that happens after the FORTRAN or C Convention: 

  0, 1, 2, 3, 4 5, 6, 7, 8, 9

versus 

  0, 2, 4, 6, 8, 1, 3, 5, 7, 9

For a large array, I have to make sure That my first 32 threads are in the same warp. What is the correct way to generate a linear index?

Your thread has been set in 32 groups. Threads fall from 0 to 31 in the first tranche, 32-63 on the second and so on. If threads 32%! = 0 , the warp is full of "shadow" threads (so you have to make this thread a mechanism to access the wrong memory position, usually a if statement).

You are not able to change this order, so the first 32 threads will always be in the same warp. Despite being in the first taana, it does not guarantee that this warp will be executed in the first place, SM. Will tell about the time of war at your facility.

Answer:

Threads were classified as viruses in the order of X, Y, Z. Therefore, in a 16x16 threadbob the first 32 thread thread will have threads in the following order:

Warp: thread ID (x, y, z) 

  0: 0, 0,0 1: 1,0,0 2: 2,0,0 3: 3 , 0,0 ... 15: 15,0,0 16: 0,1, 17: 1,1,0, 18: 2,1,0, 19: 3,1 ... 31: 15, 1,0

HTML/CSS - Automatically set height width from background image? -

-
Long time ... I do not think it's possible, but I'm shocked before! I tag anchor tags, all of which are background images, all 300px wide but their height is all the difference, is it really set to do without typing altitude? Is it to set the dimensions of BG URL? Thank you! I do not think people understand - my mistake is to hurry the question. Here is the code as an example: # ago -1 {width: 300px; Height: 410px; Background: url ('/ image-1.jpg');} # East -2 {width: 300px; Height: 420px; Background: url ('/ image-2.jpg');} # Pre-3 {width: 300px; Height: 430px; Background: url ('/ image-3.jpg');} # Pre-4 {width: 300px; Height: 440px; Background: url ('/ image-3.jpg');} & lt; A href = "#" id = "ex-1" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "ex-2" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "pre-3" & gt; & Lt; / A & gt...

I am thinking that there is something that I can do better so that my process list should start with the command with MySQL Be clear Currently I am looking for a lot: 17325 user_a localhost db_1 sleep 1132 NULL 17464 user_a localhost db_1 sleep 1124 NULL 17983 user_a localhost db_1 sleep 1078 null 18113 user_a localhost db_1 sleep 1068 NULL 18207 user_a localhost db_1 sleep 1060 NULL 18231 user_a localhost db_1 sleep 1058 NULL 18353 user_a localhost db_1 sleep 1047 NULL 18447 user_a localhost db_1 sleep 1040 null 18489 user_a localhost db_1 sleep 1036 NULL 23408 user_a localhost db_1 sleep 637 NULL Something in my phpscript is that I want to clean it Can i The script looks like: Select the ID from $ q = 'db_1 where fkId = 2'; $ Ar = mysql_query ($ q); ($ Line = mysql_fetch_array ($ qr)) {echo ($ row ['id'];} Thanks in advance! I'm guessing that when you have 10 threads, you're constantly using the connectio...

c - What is the address of buf (the local variable in the main function)? -

-
I had exercise with programming in c or classes and I followed the question: Is Buf (local variable in main function)? Either enter the answer in hexadecimal format (like 0x 8 "digits" 0-9 or A-F, 0xbfff0014) or in decimal format. Note here that we want the address of the buff, not its content. The code looks like this: int main (int argc, char * argv []) {while (1) {four buff [1024] = {0}; Int r; .... I then started the code and put the built code in the buff [1024] line and in Typed Gdb p & amp; Buf and it gives me results: 0xbffff0f0 But when I use it in this quiz it gives me the result that this value is wrong. My question is this: Is this the name of the Buff variable (P & E)? Or if not, why not? Exercise is done on the virtualbox machine, so I think everyone should be the same address There is no correct numerical answer, the address may vary from one time to another, it is a programming drill that you say the following three...
