If you like quines with a visual output like this, I recently taped out an self-reproducing ASIC which displays it's own Verilog source over VGA. https://github.com/jar/ttsky26a_prime_quine You may view the simula

I have a Radeon 7900 XTX 24GB and have been using the deepseek-r1:14b for a couple days. It achieves about 45 tokens/s. Only after reading this article did I realize that the 32B model would also fit entirely (23GB used). And since

An ARM supercomputer was already #1 in 2020 [0]. The Japanese Fugaku is also notable because it doesn't use GPUs to achieve high performance, but rather wide vector units on the CPU. [0] https://top500.org/system/

I love these puzzles. GNU C supports a label as value for computed goto. This is useful for direct threaded dispatch. You trade off a branch instruction for an address lookup, but it makes the code more structured. int main(void) {

I wrote a short paper for HPEC that included some power and performance benchmarks and analysis on the HiFive Unleashed U540 SoC [0]. The SoC isn't open source as some suggest although I believe the core is based on the open source Ro

You don't have to worry too much about the low Earth orbit (LEO) sateillites as they will deorbit soon enough. My understanding is that there is also ongoing research into methods to deorbit them at end of life.

There are several efforts including VexCL [0] expression templates, OpenACC [1] preprocessor, Kokkos [2] template metaprogramming, SYCL [3], and many other similar projects. Parallel programming for non-trivial parallelism is still...non-tr

Don't the inevitable methane leaks from natural gas create more of a GHG effect than the CO2 emitted from burning it? It's not just the environment disasters like in California, but everyday minor leaks.

John Gustafson is on the board of Rex Computing, a small semi startup. They claim to have taped out last year, but I don't know if the chip has been validated or if it had posits in silicon, but I know that is one of their longer term

I may be somewhat qualified to speculate...Based on my experience with both Intel's and AMD's OpenCL implementations for their CPUs, I suggest that Intel has a much better vecorizing compiler than AMD. The benchmarks they are runn

It applies to architectures with caches https://en.wikipedia.org/wiki/Cache_coherence Epiphany-V does not have caching. You explicitly move data around in software. Some software abstractions are better than others.

I think a heterogeneous product was implied in that post, but I don't blame you for the confusion. The Epiphany-V is still homogeneous because of the time/funding constraints.

It's backward compatible with Epiphany-III...so it's still Epiphany ISA with new instructions.

Consider that many instruction and data caches are at the 16-32 KB scale. It's obviously a big criticism of the microarchitecture but you have a linear tradeoff between number of cores and available core memory. One core with 64 MB o
