[LLVMdev] LLVM optmization
The following C test program was compiled using LLVM with -O3 option and MSVC with /O2. The MSVC one is about 600 times faster than the one compiled with the LLVM. We can see that the for loop in MSVC assembler is solved in the optimization pass more efficiently than that in LLVM. Is there an way to get a optimization result in LLVM like that of the MSVC?

Faking system time
Hello all. I am trying to use WINE to make a windoze-only development environment (very rudimentar, command line cross-compiler and stuff) under Linux, because GNU make is far superior from the M$'s 'nmake'. Anyway, I have some trouble with expirating licenses and stuff, and the solution is to revert the system date back to some valid thing and then compile. Since I am now running

Problem with definition of slist in CFEngine
Hey folks, I have a problem with the definition of a variable of type slist in CFEngine on # uname -a ; cat /etc/redhat-release Linux policyhub.example.com 3.10.0-693.el7.x86_64 #1 SMP Tue Aug 22 21:09:27 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux CentOS Linux release 7.4.1708 (Core) I'm not sure if its valid to ask CFEngine questions on this mailing list, but as far as I'm running on

Xen guests clock is exactly 2 hours before dom0 time
Hi list, one and hopefully last strange thing I figured out ist the systime of my guests. Dom0 uses ntp for time syncronisation. I set the time on my guests manually but after reboot any machine (Windows server, XP, Freebsd, even PV Machines like ubuntu) all run local time - 2 hours. /proc/sys/xen/independent_wallclock is set to 0 so actually the time should be set by dom0...(?)

[API reference] confused by CPU time term
Hi, everyone I'm writing a virtual machine monitor based on libvirt. As I read the api reference, I found I'm confused by some terms. 1, What is cumulative I/O wait CPU time? API reference says that VIR_NODE_CPU_STATS_IOWAIT indicate cumulative I/O wait CPU time. I'm confused by this time. As far as I know, when cpu meets IO wait situation, it will schedule another task, so,

[LLVMdev] LLVMdev Digest, Vol 55, Issue 16
1. Re: LLVM optmization (Bill Wendling) Hi, The IR is not wrong. I said that the assembler generated by MSVC is quicker. We can see that the for loop, in the TESTE function, is done without jump's in the MSVC and with jumps in LLVM. I think thats the point. If we don't use threads, the result is the same. My test were done with one billion interactions in the for loop. The MSVC

Shows that as the MCU increases, the OpenMP extra overhead is amortized and OpenMP becomes as fast as the pthreads implementation. The last chart http://lampiao.lsc.ic.unicamp.br/~piga/gsoc_2008/systime.png Shows that both pthreads and OpenMP overhead decreases as what seems to be a logarithmic function of the MCU size. This was a great experiment, and from what I can conclude, the OpenMP

GSoC - Theora multithread decoder
Hi, This email is to inform what I have been doing since the mid-term. After the mid-term I worked on a pipeline implementation with OpenMP. As I said before I did a pipelined implementation of these functions: (c_dec_dc_unpredict_mcu_plane + oc_dec_frags_recon_mcu_plane) and (oc_state_loop_filter_frag_rows + oc_state_borders_fill_rows) as explained in my previous email. But the results were

how to initialize random seed properly ?
I want to start R processes on multiple processors from single shell script and I want all of them to have different random seeds. One way of doing this is sleep 2 # (with 'sleep 1' I am often getting the same number) ... set.seed(unclass(Sys.time())) Is there a simpler way without a need to sleep between invoking different R processes ?

Updating hardware clock from cron
Is there a package to do this? Normally the hardware clock is set during shutdown if one is running ntpd. But if a long-running server shuts down unexpectedly, this isn't done, and the hardware clock might be off by a lot when it comes back up. So setting it periodically from a cron job could be useful. What do others do? Adding a one liner to /etc/cron.daily that invokes

a strange behavior on a small memory system with tun0
Hello I am using openssh as vpn on a router with freewrt.org and rsync to sync my local data to a remote server. Everything works fine for me so far. The only problem is that the channel-1 (tun0) goes down on the router after 50-200MB transfered via tun0 or after 5-20 hours only with a ping to the server . Channel-0 is still working. Tcpdump shows that a ping from the router to the server via

thread taskq / unp_gc() using 100% cpu and stalling unix socket IPC
Hi there We have a pair of servers running FreeBSD 9.1-RC3 that act as transparent layer 7 loadbalancer (relayd) and pop/imap proxy (dovecot). Only one of them is active at a given time, it's a failover setup. From time to time the active one gets in a state in which the 'thread taskq' thread uses up 100% of one cpu on its own, like here: ---- PID USERNAME PRI NICE SIZE
