I would love to try but there is no work available.

There will be no CPU optimizations either...there is either a lack of knowledge or a lack of interest, probably the former.

There will be no such changes to the code base. Posts concerning OpenCL or HSA are pointless.

This is a constant nuisance...

Hi there Mr. Server Admin Guy,

IT'S NOT WORKING...

Just a short question:



Why does ralph@home also download minirosetta_3.71 ?

Gloomy outlook but thanks for your efforts!

A little comparison Rosetta / folding@home:

Rosetta: situation described as above

folding@home: excerpt from their blog


New Gromacs core. The Gromacs core continues to be a workhorse core for CPU clients and we are working on releasing an updated core with more broad hardware support, including support for AVX, which will give some donors an automatic performance boost.

Seriously, they should fork the code and rewrite it from raw.


Yeah, that's not gonna happen for sure. Maybe instead of starting from scratch, it's more important to identify and optimize just the worst kludges like the one above.

I think rjs5 already profiled the binary to look for those occurrences.

I do understand that there is not much space for compiler optimization otherwise.

@rjs5: This is very interesting, thank you!

Maybe one step forward would be to implement your solution to the "Rosetta screensaver tragedy".

It would alleviate the need for a statically linked binary so that the dynamically linked binary can at least use some optimized libraries...

What are the compiler flags for release mode?

I didn't mean to be rude, it's just when you install the 32-Bit version of libglu1-mesa, apt-get will install >50MB worth of 32-Bit libraries as dependencies.

That kinda sucks. I installed the libraries but I can't get more jobs from ralph because "Fr 09 Okt 2015 23:45:32 CEST | ralph@home | (reached daily quota of 8 results)"

EDIT: ../../projects/ralph.bakerlab.org/minirosetta_beta_3.64_x86_64-pc-linux-gnu: error while loading shared libraries: libGLU.so.1: cannot open shared object file: No such file or directory

Oh, for crying out loud, please provide a 64-Bit binary.
