I've not seen any rationale why sites haven't done something sensible. Sensible, like allowing automation without storing your password to use sshpass, for instance; then if you insist on MFA, that can be done when issuing an eph

The merge complexity in darcs 2 really hasn't been an issue in my usage. As I understand it, it is resolved for darcs 3, but maybe I misunderstood that from skimming what was going on. (The new theory seems to be different to Pijul&#

I haven't used pijul, but I'm familiar with darcs and manually resolving the conflict with a new patch. You still have the conflicting patches, which you can manipulate. There's no claim of magic resolution, and I don'

> maybe pijul is different No "maybe"; that's the point. Why does modelling something fundamental, like conflicts, decrease confidence in the approach?

The current instrumentation is already pretty stunning, I think particularly to someone with a background in experimental physics.

That seems to suggest there weren't distributed systems before git (like the proprietary one git was written to replace). I think there's enough wrong with git after long experience with revision control in collaborations; I&#x27

For code using intrinsics (not assembler) https://simd-everywhere.github.io/blog/ might be helpful, including on x86_64, though it doesn't provide runtime dispatch. GCC itself knows a level (sse4.2?) of x86_64 in

by gnufx 6y ago
GNU libc, at least, has versions of a variety of functions for different SIMD variants with runtime dispatch. You can provide that with GCC attributes, or explicitly with the cpuid-like mechanisms typically used in linear algebra libraries

I see comments just demonstrating Cleese's points. He talks about being kind to people and in return gets nastiness in defamatory statements, apparently people choosing to accept things written by the press he complains about, which h

I actually meant the bit about "even big endian systems in general." I know of things missing on BE ppc64 from EPEL6 packaging. (There's a significant number of things of interest to me missing on ppc64le, but desktop stuff

What sort of problems are there specifically with current GNU/Linux distributions on big-endian systems? Fedora/RHEL, SUSE, and Debian are all supported on s390x, though doubtless many packages aren't very relevant on it. I

Thanks. That's rather what I'd expect, but I was surprised at hardware being announced with (some version of) the vector extension and wondered what support there would be for it. Is it reasonable to ask what you might expect in

by gnufx 6y ago
GCC doesn't have support for this system's vector unit in the development source as far as I can see. Does LLVM?

The sort of things being targetted by one effort are listed at https://shakti.org.in/processors.html whether or not that has anything to do with popcount. This SiFive one seems interesting for having the vector extension,

This must have been downvoted by people who don't understand HPC, as usual here. While, typically, latency is the most important metric for an HPC fabric, it's not the only one that may be more important than bandwidth (message r

I agree on monoculture, the point is it does appear to fail (and the Cisco usNIC offering looked better). There are alternative HPC fabrics in new hardware: OPA (although being canned by Intel), Shasta (Cray), BXI (Bull), and Tofu (Fujitsu

I'm not sure it has to be IB. Alibaba (I think) use RoCE, which can have fairly respectable latency. Which ones do have IB apart from Azure, Oracle, and specialist HPC vendors? But yes, when I last knew, EFA was still an order of mag
