abstract = {To complement existing compiler-optimization methods we propose a programming model and a runtime system called BMDFM (Binary Modular DataFlow Machine), a novel hybrid parallel environment for SMP (Shared Memory Symmetric Multiprocessors), that creates a data-dependence graph and exploits parallelism of user application programs at run time. This thesis describes the design and provides a detailed analysis of BMDFM, which uses a dataflow runtime engine instead of a plain fork-join runtime library, thus providing transparent dataflow semantics on the top virtual machine level. Our hybrid approach eliminates disadvantages of the parallelization at compile-time, the directive based paradigm and the dataflow computational model. BMDFM is portable and is already implemented on a set of available SMP platforms. The transparent dataflow paradigm does not require parallelization and synchronization directives. The BMDFM runtime system shields the end-users from these details.},

I achieved a speedup of 10000 compared to the CPU implementation. I'm quite happy with that. Note that the chart uses a logarithmic scale, otherwise most of the runs would not be visible.

For example, the CPU took a bit more than 30 minutes to solve the biggest input, the parallel (CPU) version took a bit more than 8 minutes. Meanwhile, my best handwritten implementation on the GPU takes less than 200ms for the same problem, and the version using the optimized cuBLAS library takes just 64ms.

Edit: upload chart with white background, the transparent version didn't fare well with my Fediverse clients.

Hi R people! Could you suggest some guides and links on how to set up parallel processing with `foreach` that can work both on Windows and Linux/Mac? I'm searching for guides on the net, but most of them seem to have become obsolete. Thank you!

🚀 Intel Developer Tools v2025.1 is here with new OpenMP 6.0 features!

The Intel® Fortran Compiler enhances #OpenMP 6.0 support with two powerful additions: WORKDISTRIBUTE for efficient thread-level work distribution, and INTERCHANGE to reorder loop nests for improved parallelism and optimization.

A big win for HPC and embedded devs!

👨‍💻 Oh, the eternal quest for a "good" parallel computer, like a quest for a unicorn that can also do your taxes. 🦄💻 Apparently, GPUs are only good for "predictable" tasks – maybe like predicting the inevitable death of your dreams for a universally versatile chip. 😂 Why not just ask for a toaster that can handle your email while you're at it? 🍞📧

another example (Newton-Raphson zooming for Mandelbrot set):

with 7 threads : 105.26 Watts * 12.2 seconds = 1284.6 Joules
with 1 thread : 54.17 Watts * 52.1 seconds = 2822.3 Joules
sleeping / idle overhead : 26.01 Watts
7 threads minus overhead (105 - 26.01)W * 12.2s = 964 Joules
1 thread minus overhead (54.17 - 26.01)W * 52.1s = 1467.2 Joules
if the machine would be on/idle anyway: 105.26W * 12.2s + 26.01 W * (52.1 - 12.2)s = 2321.9 Joules

thus using more threads saves energy even when parallelism efficiency is far from perfect: best to get in/out as quickly as possible so you can turn the machine off (ideal case) / leave it fully idle (second best)

power consumption doesn't scale linearly with load (a little load increases a lot vs baseline: 1 thread doubles idle power consumption, but high load doesn't increase much more: 7 threads quadruples idle power consumption)

measured with turbostat on Debian, AMD 2700X CPU with default CPU scaling governor, usual browser/email/etc running too
