问题 Here is my code, which creates 2d array filled with zeros, array dimensions are (795,6942): function zeros($rowCount, $colCount){ $matrix = array(); for ($rowIndx=0; $rowIndx<$rowCount; $rowIndx++){ $matrix[] = array(); for($colIndx=0; $colIndx<$colCount; $colIndx++){ $matrix[$rowIndx][$colIndx]=0; } } return $matrix; } $matrix = zeros(795,6942); And here is the error that I receive: Allowed memory size of 134217728 bytes exhausted (tried to allocate 35 bytes) Any ideas how to solve this? 回答1

问题 I need a way to find if the character ('<') has hit a wall (Black pixel Graphic) -On a ZX81 game. I'm been looking at another game... which uses code if peek(peek 16398 +256*peek 16399) = code "**blackpixel graphic**" then ... Which seems to work for them... Is this correct code? I'm not really knowledgable with addresses and getting memory and stuff. Please help me... -If you know a better way. Please answer :) Thanks, 回答1: Located at addresses 16398 and 16399 are two bytes that form the

问题 HI i wrote a simple block collecting program that was working just fine and dandy until i added sound. Then all the sudden i get a MemoryError which is something ive never seen before. my code is attached along with the sound(wav) file that seem to be the problem. Any help would be great, and yes the code and the sound are in the same folder along with tons of other programs and pictures and stuff. import pygame import random import pygame.mixer winsound=pygame.mixer.Sound('winning.wav')

问题 So the idea that I have about coalescing memory accesses in CUDA is, that threads in a warp should access contiguous memory addresses, as that will only cause a single memory transaction (the values on each address are then broadcast to the threads) instead of multiple ones that would be performed in a serial manner. Now, my bus width is 48 bytes. This means I can transfer 48 bytes on each memory transaction, right? So, in order to take full advantage of the bus, I would need to be able to

问题 Does my java application continue running while jmap is taking its memory dump? 回答1: Your application is stopped. The only practical way to get an accurate heap dump would be to stop all application activity while the dump is being created. Whether this is a "brief" pause or a "long" pause depends on how much is dumped. If you use "-dump" then you will dump the entire heap, including unreachable objects. If you use "-dump:live" you will only dump reachable objects ... but that also entails

问题 I have a problem where I have a pointer to an area in memory. I would like to use this pointer to create an integer array. Essentially this is what I have, a pointer to a memory address of size 100*300*2 = 60000 bytes unsigned char *ptr = 0x00000000; // fictional point in memory goes up to 0x0000EA60 What i would like to achieve is to examine this memory as an integer array of size 100*150 = 15000 ints = 60000 bytes, like this: unsigned int array[ 100 ][ 150 ]; I'm assuming it involves some
