I'm writing a highly parallel application that's multithreaded. I've already got an SSE accelerated thread class written. If I were to write an MMX accelerated thread class, then run both at the same time (one SSE thread and one MMX thread per core) would the performance improve noticeably?

I would think that this setup would help hide memory latency, but I'd like to be sure before I start pouring time into it.

What's the difference between logical SSE intrinsics?

as seen on Stack Overflow - Search for 'Stack Overflow'
Hello, Is there any difference between logical SSE intrinsics for different types? For example if we take OR operation, there are three intrinsics: _mm_or_ps, _mm_or_pd and _mm_or_si128. My questions: Is there any difference between using one or another intrinsic (with appropriate type casting)… >>> More

Hi, My Professor found out this interesting experiment of 3D Linearly separable Kernel Convolution using SSE and OpenMP, and gave the task to me to benchmark the statistics on our system. The author claims a crazy 18 fold speedup from the serial approach! Might not be always, but we were expecting… >>> More
Combining prefixes in SSE

as seen on Stack Overflow - Search for 'Stack Overflow'
In SSE the prefixes 066h (operand size override) 0F2H (REPNE) and 0F3h (REPE) are part of the opcode. In non-SSE 066h switches between 32-bit (or 64-bit) and 16-bit operation. 0F2h and 0F3h are used for string operations. They can be combined so that 066h and 0F2h (or 0F3h) can be used in the… >>> More

Stack usage with MMX intrinsics and Microsoft C++

as seen on Stack Overflow - Search for 'Stack Overflow'
I have an inline assembler loop that cumulatively adds elements from an int32 data array with MMX instructions. In particular, it uses the fact that the MMX registers can accommodate 16 int32s to calculate 16 different cumulative sums in parallel. I would now like to convert this piece of code to… >>> More

Hi! Where can I find information about common SIMD tricks? I have an instruction set and know, how to write non-tricky SIMD code, but I know, SIMD now is much more powerful. It can hold complex conditional branchless code. For example (ARMv6), the following sequence of instructions sets each byte… >>> More
