To decode? Why does the user care how long it takes to decode, they care how long it takes to run. We can provide upper bounds for exp, sin, and erfc too.

I suspect this guy never compiled the code he posted. Not that his claim was completely wrong, but gcc-4.4.4, gcc-4.5.1, and clang-1.1 (LLVM-2.7) all fail to vectorize that snippet, with `gcc-4.5.1 -O3 -ftree-vectorize -ftree-vectorizer-ve

T-mobile gives you a $20/month discount. I agree that it doesn't make sense with the other carriers. An important issue is that the carriers operate on different bands so your phone is still tied to a specific carrier (if you want 3G to w

If you own your phone, T-mobile smartphone plans are $20/month cheaper. That's $480 over a 24-month contract, it doesn't pay to get the subsidized phone. (Yeah, unless you get an N1, it's still a branded phone with some crapware, but they

Show me any CL library that is competitive with numpy+scipy. Similarly, I do a lot of distributed memory work, for which MPI is necessary. For CL bindings, all I know of is CL-MPI and mpi4py trumps it in every way. I need parallel linear

Same here, but that might not be the best example since there is `pydoc multiprocessing`, perhaps integrated with your editor.

It hasn't been fair to compare single-CPU performance in a long time, machines on the top500 either use commodity x86-64 chips, or (BlueGene) much slower chips with good memory and power efficiency (NEC is a notable exception). But it's wo

Then you aren't multiplying doubles, it would be a shame to get a completely wrong answer on an ill-conditioned problem because the implementation disregarded the spec, cf. "the fastest way to process UTF-8 is to truncate it to ASCII", "the

In "real" engineering, every project is slightly different. If they were the same, you wouldn't need an engineer. The engineer knows about many projects involving similar components, the details and the way they are put together will be d

The LLVM website doesn't seem to have deprecated the clang name. Clang 1.1 is included with the LLVM 2.7 release. So what exactly is at 2.0, and has this thing been released?

Huh? Double precision SIMD? SSE2 instructions aren't slower than SSE.

LLVM 2.0? That was released over 3 years ago. Maybe they mean LLVM 2.7?

Um, this number sounds high. My recollection is that there is a $20/month difference in price so you are effectively paying an extra $480 towards a phone over two years. If the difference in up-front cost for the device is less than this,

This hoists all dependencies to the top level, it looks decent because the dependency graph is entirely static. Suppose you want more runtime flexibility, such as replacing every instantiation with a runtime choice between 3 implementation

by jedbrown 16y ago
Sometimes the instantiation is really private. Lifting all dependencies to the top level isn't progress, especially if you want plugins or a friendly interface.

The wireless was/is free as long as you spend at least $5 per month. All you need is $5 on a gift card to enable the wireless for the month. So buy a $5 gift card and at the end of the month, spend that $5 and put $5 more on the card. Si
