I just wanted to bring it to your attention that the university of
Pittsburgh provides a HPC-Patch for OpenSSH 4.7 wich may is worth looking
at (include it into the base if possible? who knows..). :)
Is crypto really a bottleneck for non-HPC users? My <AUD$500 PC can do
AES128 at 0.7GBPS and RC4 at 2.25GBPS.
Both 1Gbps ethernet and multiple cores are pretty common on cheap
systems, and even cheap laptops, these days. Most testing and
measurement of this work was done with two workstations (around a couple
K $US) 1Gbps, 8 cores. On those systems we did not fully utilize even
four of the cores, and we've seen very significant improvement on
dual-core systems which are pretty much standard [in terms of new
hardware] these days.
We've been working other modifications, aiming towards 10Gbps, which I
would not argue are more HPC-specific.
It is very unlikely that this patch will be integrated - it adds threads
to OpenSSH, which introduce many new security considerations.
Using threads is really just a means to an end, and happened to be the
most convenient means. If that's a show stopper for you guys, we can
work on that. Are there any other issues?
thanks for the feedback,
