Folding Forum

This thread is about introducing Apple iGPUs, not AMD GPUs on macOS, and I intend to keep it that way. If raspberry pis have a role in FAH, then iGPUs with a similar power consumption and vastly more FLOPS definitely do. Especially when upstream OpenMM has been tested against the iGPU in question. T...

The Apple Silicon things indeed do not have fp64. In fact the metal shading language doesn't have that double data type at all. I think it would be very reasonable to compile a version of OpenMM with CPU-resident fp64 for macOS arm64 since the vast majority of GPUs attached to such a platform would ...

I still don't have access to a sample of wuresult_01.dat. But based on the current bunch of files in the work folders, my guess is that it includes at least the final positions.xtc. This XTC format from gromacs is compressed both by reducing precision and by a kind of delta-coding described in https...

The "see also" links mainly concern the packaging of the cores. At that time I didn't look too much into returning work as my bottleneck was download time (download time has the processor idle, upload... i don't know actually!). In addition, multi-threaded LZMA2/xz isn't really necessary a...

OpenMM has had support for using OpenCL with Apple M1 since circa 2022. It would make sense for people currently crunching on their Apple Silicon machines to also use the GPU part of the chip. While OpenCL deprecation is a concern, the API still works. According to https://github.com/openmm/openmm/i...

Just to be clear... LAR probably did not enable 8.5 yet the thing is, there's not anything for LAR to enable. the blocking is coming from the FAH client itself. My allow list is <allow v='127.0.0.1 10.0.0.0/8 192.168.0.0/16 172.16.0.0/12 169.254.0.0/16'/> This only because I use fahctl and lufah fro...

Hah! I've fixed it! The following works for playing it safe: Gotta unescape by one level.

I got back to folding after some time spent crunching Mersenne primes, and being the eager tester that I am, I installed the v8.5.3 client. Then I opened my old trusty "Folding@Home In The Dark" client from LAR systems... Oops! No connection! A quick peek into the browser networks tab &...
