You may be interested in the Linux kernel docs[0]. We use it at work to better identify faults with devices hanging off he PCIe bus, namely GPUs and interconnects. [0] https://www.kernel.org/doc/Documentation/PCI&#

That will make a good weekend read thanks! Others may be interested in Data Structures for Text Sequences by Charles Crowley[0] which describes Piece Tables. This is the basis for the Vis editor[1]. [0] https://www.cs.unm.edu&#x2F

I've only skimmed this but there seems to be a focus on customizing and plugins from the get go. I think it's worth getting to know Vim "as is" before doing such things. Indeed there certainly some things that aren'

LibreSSL aims to be a mostly API compatible replacement for OpenSSL, BoringSSL does not. Literally the first text on the BoringSSL web page. BoringSSL is a fork of OpenSSL that is designed to meet Google's needs. Althoug

Not sure why this appears to be been down voted. Git's command-line interface IS terrible. Certainly not unusable as most of interact with it every day. A somewhat satirical example of this is Steve Losh's Git Koans. http:/&

The trouble with this isn't the lack of available options (indeed one may argue there are too many). But rather having everyone agree on something with a common API. Also has anything else seen heavy prolonged production usage?

I'm surprised at the number of daemons in OpenBSD's base that were calling fork() and not then calling exec(). It seems they're now all adopting this which is good.

This option only got added in recently. I think it would have been better if this were pointed out in the post. But trying not to sound too snide there's something to be said for checking the man page before copying config off the inte

Unfortunately it will be years before myself and many others get to use BPF on our production systems as we have to run an "enterprise" distribution like RHEL or god forbid SLES. But yes it certainly is good to see steps being mad

Just wanted to share this video given at ANL recently which goes into the cost of communication in such methods. It has a HPC focus but the presentation is quite digestible. https://www.youtube.com/watch?v=TUViqCd9EKk

Anyone have details on the cache design for this? 2048 bits is much larger than most cache lines in chips today.

There's a click bait title if ever I saw one. A single benchmark is run without numbers and the AMD part only completes just ahead of the Intel part (which is down clocked by 200Mhz). Not got anything against AMD, just the title. Reall

I've not dug into this enough yet but all prior generations of Nvidia GPUs have had caveats when adding steps to unify main memory. It certainly isn't "one address space" as far as the OS is concerned, perhaps Nvidia is

Do you still need to use vector instructions on KNL to get top performance? Yes, but this is also the case for regular Xeons. If so then forgot about "familiarity" when rewriting. When I say "familiarity"

I agree with all of your points but I think KNL will be a turning point. Traditional multi core CPUs simply aren't an option to advance in the HPC space any more. Per generation there's not enough of a performance improvement to m
