(I've already posted this message month ago, but nobody answered, may be it was not delivered to newsgroup?) Hello, All. I wrote an encoder-decoder based on example from OGG-Vorbis SDK. This encoder can encode a large amount of small WAV-files with equal parameters into one sound archive. Then I decode this sound archive back into large amount of small WAV-files. Theese files are

Hi everybody! I'm creating an object of a S4 class that has two slots: ListExamples, which is a list, and idx, which is an integer (as the code below). Then, I read a data.frame file with 10000 (ten thousands) of lines and 10 columns, do some pre-processing and, basically, I store each line as an element of a list in the slot ListExamples of the S4 object. However, many operations after this

...t; iteration and/or instruction distances to this interface. Would it make sense to specify a prefetch distance in bytes instead of cache lines? The cache line might not be known at compile-time (e.g. ARM big.LITTLE), but it might still make sense to do software prefetching. > class TargetStreamBufferInfo { > /// getNumLoadBuffers - Return the number of load buffers available. > /// This is the number of simultaneously active independent load > /// streams the processor can handle before degrading performance. > /// > int getNumLoadBuffers() const; > >...
