I'm attempting to add a new member variable to the Instruction class but I get assertion errors when I run lli. All I add is the following line to the private portion of the Instruction class definition. bool b; The error usually is: lli: /development/Contracts/DOVE/src/c/llvm/include/llvm/Type.h:329: void llvm::Type::dropRef() const: Assertion `isAbstract() && "Cannot drop a

I just noticed I'm getting some pretty extreme CPU usage on my Samba server when transferring files. The Samba server has a quad core 2.0gHz Core2. During transfers, CPU use spikes to 100-200% with a throughput around 30MB/s. I'm using the registry config backend. [global] use kerberos keytab = True server string = X dns proxy = yes log file =

Mark Schilling a ?crit : > I recompiled with FIXED_POINT and CPU utilization stays below 4%. This is a great improvement. > So how can I fix this to work with floating point ? OK, so it looks a lot like a denorm problem. The issue is basically that there are filters that decay exponentially, so when the input suddenly goes to zero, then the filter's output value becomes smaller and

I am using puppet 0.23.0-1 from Fedora Core 7 for a while and just realized that puppet use over 90% CPU every 30 minutes for about 10minutes. Anyone has the same issue?

I've been looking over Benjamin Schwartz's Skeleton A-mod proposal. I've been pretty busy with other projects over the past few months, so haven't had a chance to look at Ogg indexing until now... In general, I think Benjamin's ideas are sound, they're improvements, and I'm open to being convinced to take them in the next index version. We may as well get the index

Hi Jean-Marc, I recompiled with FIXED_POINT and CPU utilization stays below 4%. This is a great improvement. So how can I fix this to work with floating point ? Thanks.

In the general case, I think you have to be conservative about this because programmers may deliberately want this kind of "wraparound" behavior, e.g., with periodic boundary conditions. But 99.9% of programs probably don't need that so it would be bad to penalize them for this corner case. In such a situation, I think you just have to support both choices, but choose the

Hi Jeff, Hi Jean-Marc, I first modified the FPU control word to raise an exception whenever a denormal is used. Then I used the debugger to locate the exceptions and added VERY_SMALLs where they seem to fit well. Although I got CPU usage as low as 10%, I seriously lack knowledge of how things work inside speex. So just changing some code is not the best idea for me. My second attempt was to

Hola, Estoy intentando realizar un ajuste a un modelo setar con R y me surgen problemas a la hora de representar el modelo setar sin la constante. El código es el siguiente: # Estimacion TAR(2;2,2) con delta 1: mod.setar <- setar(x, m = 2, mL = 2, mH = 2, thDelay = 1) mod.setar summary(mod.setar) mod.setarc<-setar(x, m=2, mL=2, mH=2, thDelay=1, include=c("none")) ##eliminamos

The subject says it all really. Question 1. Here is some code created to illustrate my problem, can anyone spot where I'm going wrong? Question 2. The reason I'm following a manual specification of models relates to the fact that in reality I am using mgcv::gam, and I'm not aware that dredge is able to separate individual smooth terms out of say s(a,b). Hence an additional request,

Dear R community, I've been writing simple functions for the past year and half and have come across a similar problem several times. The execution of a function within my own function produces NaN's or fails to execute as intended. My conundrum is that I can execute the function outside of my function without error, so it's difficult for me, as a novice functioneer, to figure out

The below seems to give me several minutes of 15-60% cpu usage. As far as I can tell there doesn''t seem to be anything really wrong with my configuration. Anyone have any idea why this might be the case? I also get about 6% memory usage. This is a 3.0 ghz Xeon with 2 gigs of memory. class apache2 { file { "/etc/apache2": recurse =>

Hi all, I''m not sure what qemu-dm does or how to debug its high CPU usage. Any one mind giving me a clue? - Brian _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I have couple of HVM guests on xen 3.2. When guests boot, qemu-dm uses alot of cpu for approx 20 minutes post boot then load drops to average 0.50. I did some debugging and see this is going on, I suspect display output is using the CPU. Disabling VNC and SDL didn''t help with the CPU usage. any ideas how to reduce the cpu or stop it all together? My setup is as following: Xen

Hello, Using one of Brendan''s dtrace script prusage and prstat, I was able to find the process that is consuming high cpu. I also have a test case that can trigger this high cpu usage. Questions are a) how do I proceed from here? b) how do I figure out which thread is using this high cpu? c) how do I figure out which piece of code is causing this problem? Thanks This message posted from

The setup: Downloaded from samba-2.2 branch of cvs as of 9 okt. (also tried 2.okt) installed on a redhat 7.1 2.4.7 i386 system The problem: the smbd process serving a NT 4.0sp6 workstation uses 80+ % cpu smbstatus reveals that the pid is attached as "smbguest" to the IPC$ share. The workstation has opened up another IPC connection at this point. The problem do not show up in
