"How to properly cast a global memory array using the uint4 vector in CUDA to increase memory throughput?",
"There are generally two techniques to increase the memory throughput of the global memory on a CUDA kernel on compute capability 1.3 GPUs; memory accesses coalescence and accessing words of at least 4 bytes. With the first technique accesses to the same memory segment by threads of the same half-warp are coalesced to fewer transactions while be accessing words of at least 4 bytes this memory segment is effectively increased from 32 bytes to 128.\n\nUpdate: solution based on talonmies answer. To access 16-byte instead of 1-byte words when there are unsigned chars stored in the global memory, the uint4 vector is commonly used by casting the memory array to uint4. To get the values from the uint4 vector, it can be recasted to uchar4 as below:\n\n#include <cuda.h>\n#include <stdio.h>\n#include <stdlib.h>\n\n__global__ void kernel ( unsigned char *d_text, unsigned char *d_out ) {\n\n int idx = blockIdx.x * blockDim.x + threadIdx.x;\n\n extern __shared__ unsigned char s_array[];\n\n uint4 *uint4_text = reinterpret_cast<uint4 *>(d_text);\n uint4 uint4_var;\n\n //memory transaction\n uint4_var = uint4_text[0];\n\n //recast data to uchar4\n uchar4 c0 = *reinterpret_cast<uchar4 *>(&uint4_var.x);\n uchar4 c4 = *reinterpret_cast<uchar4 *>(&uint4_var.y);\n uchar4 c8 = *reinterpret_cast<uchar4 *>(&uint4_var.z);\n uchar4 c12 = *reinterpret_cast<uchar4 *>(&uint4_var.w);\n\n d_out[idx] = c0.y;\n}\n\nint main ( void ) {\n\n unsigned char *d_text, *d_out;\n\n unsigned char *h_out = ( unsigned char * ) malloc ( 16 * sizeof ( unsigned char ) );\n unsigned char *h_text = ( unsigned char * ) malloc ( 16 * sizeof ( unsigned char ) );\n\n int i;\n\n for ( i = 0; i < 16; i++ )\n h_text[i] = 65 + i;\n\n cudaMalloc ( ( void** ) &d_text, 16 * sizeof ( unsigned char ) );\n cudaMalloc ( ( void** ) &d_out, 16 * sizeof ( unsigned char ) );\n\n cudaMemcpy ( d_text, h_text, 16 * sizeof ( unsigned char ), cudaMemcpyHostToDevice );\n\n kernel<<<1,16>>>(d_text, d_out );\n\n cudaMemcpy ( h_out, d_out, 16 * sizeof ( unsigned char ), cudaMemcpyDeviceToHost );\n\n for ( i = 0; i < 16; i++ )\n printf(\"%c\\n\", h_out[i]);\n\n return 0;\n}"

"Setting access control for different contexts in LDAP through JNDI",

After searching on this, I found that in ApacheDS, it is possible to set access control at partition level, but did not find how to set it in context level.\n\nFurther, I have the requirement that my application should be able to connected to any LDAP server (like openLDAP, ApacheDS etc..) that user specifies and perform above operations.

"How are REST api \"expand features\" implemented in SQL (without ORM)",
"REST APIs often have the feature to expand nested objects in their responses. I have an API to maintain and I would like to implement this feature. I would like to hear about how the community approaches the problem when it comes to SQL.\n\nWith an ORM it is possible to expand dynamically, at runtime, but this causes extra roundtrips to the database, and with big objects, the ORM is gonna make dozens of database queries. Ideally, I would like to limit each endpoint to a single SQL query. Therefore what is the common approach?\n\n\nParse the URL and chose the query to execute based on the expand parameter?\nFetch all the data in a single query and filter out data according to the expand parameter?\n\n\nWhat's problematic is that if I want to avoid multiple roundtrips to the database, I need to know in advance which expand combinations are possible. It is very difficult to allow deeply nested expands for instance.\n\nThanks"

"Ajax content submission",
"I have the following code, which takes a response from the Cardspring servers and attempts to send it to our site to be stored in our database. I'm having trouble getting the ajax to work correctly.
