Comparing algorithms and platforms

CPU vs GPU in Matlab

Michael Croucher’s Walking Randomly covers numerical computing for engineers, using tools such as Mathematica and Matlab. However, his series of posts starting with MATLAB GPU / CUDA experiences and tutorials is recommended for any programmer considering GPU parallelism. Michael compares optimized multi-threaded CPU algorithms to massively parallel GPU equivalents when all their extra costs, such […]

RNG Range Projection

RNG Range Projection is a new page discussing the pitfalls of projecting the output of a pseudo-random number generator with a small native range (specifically, the rand() function of MS Visual C++) into an arbitrary target range. This page essentially replicates the contents of a plain text file that used to be included with my […]

Uncontested Lock Performance

Recently I wondered about the performance cost of preemptively putting monitor locks on small library methods that might conceivably be called from multiple threads. That’s a great subject for a micro-benchmark, so I wrote a few tests in C# and Java and posted the results in Uncontested Lock Performance. As it turns out, standard locking […]
