Just curious if the protocol sends a request and waits for a response, or whether it can multiplex multiple requests on a single connection. This could improve performance over high latency links, if a lot of time is spent waiting for the response (i.e. when the hashes match). -- Travis is an organic computer peripheral.

...onvergent operations - Disabling jump threading of convergent operations - Auditing SimplifyCFG for additional transforms that break convergent guarantees *** WHY *** SPMD/SIMT programming models are a family of related programming models in which multiple threads execute in a per-instruction lockstep fashion. Predication is typically used to implement acyclic control flow that would otherwise diverge the PC address of the lockstep threads. In these models, each thread's register set is typically indepedent, but there exist a small number of important circumstances in which a thread may acc...

...llvm, clang, clang-tools-extra, > compiler-rt, libc++, libc++abi, libunwind, test-suite. The minimum that makes sense is llvm, though that defeats the point of a combined repo. I don’t think that libc++ / libc++abi make sense there for several reasons: - You very rarely need to update them in lockstep with anything else - LLVM/Clang is useful and frequently built without libc++ - libc++ is useful and frequently built without any of the rest of LLVM The same applies to libunwind. If you’re building an entire toolchain then you might want to use it, but most projects don’t benefit from it and...

It is not clear that the two should be kept in lockstep and there is certainly no mechanism to enforce that. -- Peter Dalgaard, Professor, Center for Statistics, Copenhagen Business School Solbjerg Plads 3, 2000 Frederiksberg, Denmark Phone: (+45)38153501 Office: A 4.23 Email: pd.mes at cbs.dk Priv: PDalgd at gmail.com

...ll, We're planning an Asterisk implementation consisting of two SC1425 Dell Servers using Digium T1 cards and SATA drives. The problem I'm having is the only PCI slot shares an IRQ with the SATA controller. Any altering of one device's IRQ takes the other device's IRQ with it in lockstep. I've disabled all non-essential integrated devices with no change. I'm a little worried about call quality if I can't resolve this IRQ sharing issue. So I'm wondering a few things... 1. Am I missing something with regard to the IRQ configuration? 2. Should I trust in the mot...

I'm currently running: virsh --version 1.0.2 libvirtd --version libvirtd (libvirt) 1.0.2 I have a couple questions. 1. Can I upgrade my libvirt.so version to use with an older libvirtd? In other words, does the versions of libvirt and libvirtd need to be in lock step? 2. I'm able to use virsh blockcopy, but I want to do it programmatically via C. I looked through the API and was not

For the runtime projects, another option would be to only allow standalone builds. However, the runtime projects are often built in lockstep, and so running three CMake commands when one would suffice is both annoying and also an easy way to screw things up.

I understand that dealing with this is at least partially the responsibility of the Debian QEMU Team, which is why I've CC'd them. However, this seems to suggest that qemu packaging would need to be updated in lockstep with Xen, even if someone is using qemu in kvm or standalone mode! -- -- Stevie-O Real programmers use COPY CON PROGRAM.EXE -------------- next part -------------- An HTML attachment was scrubbed...

...s that other falcons which require signed firmware (like PMU) cannot be used as of now. Our goal is to eventually have Nouveau use the same firmware as our own driver (RM), but this will take some more work. One of the obstacles being that since RM embeds the firmware, both can safely evolve in lockstep, while in the context of Nouveau we must make sure older kernels remain supported forever and either avoid incompatible changes or manage different firmware versions. - https://github.com/Gnurou/nouveau/tree/secboot is a Nouveau branch capable of loading the signed firmware.

Hi people... I want know if Source Codes Virtulization Solution from Red Hat has be release? Thanks -- Gilberto Nunes

I'm doing a huge rsync from one net to another (about a terabyte) over a dedicated DS-3. One rsync doesn't even come close to saturating the line, especially with compression enabled. Is it okay to run multiple rsyncs copying the same source to the same destination or do I have to take care that they work on disjoint sections of the source directory tree? Thanks, Skip Montanaro
