No. It pessimizes correctly behaving code to work around code that

Hi: I deleted old modules in /usr/lib/asterisk/modules before make install. I built zaptel and libpri before asterisk. Modprobe zaptel and modprobe -v wctdm executed witiout complaint. Starting asterisk produced the output below with several warnings and a failure. Can someone help, please. I double-spaced the warnings in the text below. The first warning is about music on hold because it

It seems benign, but has implications since checking time is actually not a cheap operation: adding jus ta time check alone incurs a penalty of ca. 700% compared with the time it takes to call R_CheckUserInterrupt(). Generally, it makes no sense to check interrupts at every iteration - you'll find code like if (++i % 10000 == 0) R_CheckUserInterrupt(); in loops to make sure it's not called

tl;dr: R_CheckUserInterrupt() can be a performance bottleneck within GUIs. This also affects functions in the 'stats' package, which could be improved by changing the position of calls to R_CheckUserInterrupt(). Dear all, Recently I was puzzled because some code in a package under development, which consisted almost entirely of a .Call() to a function written in

A more generic solution would be for R to throttle calls to R_CheckUserInterrupt(), because it makes no sense to check 1000 times per second if a user has interrupted, but it is difficult for the caller to know when R_CheckUserInterrupt() has been last called, or do it regularly without over-doing it. Here is a simple patch: https://github.com/r-devel/r-svn/pull/125 See also:

This seems like a great idea. Would it help to escalate this to a post on R-bugzilla, so it is less likely to fall through the cracks?

Hello, I am writing an R interface for one of my C++ programs. The computations in C++ are very time consuming (several hours), so the user needs to be able to interrupt them. Currently, the only way I found to do so is calling R_CheckUserInterrupt() frequently. Unfortunately, there are several problems with that: 1. Calling R_CheckUserInterrupt() interrupts immediately, so I have no

Hello, My problem is that I have an extension in C++ that can be quite time-consuming. I'd like to make it interruptible. The problem is that if I use the recommended R_CheckUserInterrupt() method I have no possibility to cleanup (e.g. free the memory). I've seen an old thread about this, but I wonder if there's a new and definitive answer. I just do not understand why a simple

A relatively simple way to hang

Hello, I am working on reports now where we are using MySQL (InnoDB) and Rails 2.3.4. Tables are big and there are a lot of calculation with several big tables. Please give me some suggestions whether there any gem, plugin, articles, or techniques that allows me to create heavy reports. I am even going to use cron job that allows me to calculate some middle data in order to provide heavy

I have a firewall (No NAT - just routing) configuration with a large number of chains and rules. I am now testing it on RH9 and it seems to take 100% user CPU time for more than 30 minutes for the script to run (I am still waiting for it to finish) On RH7.1 a similar set of rules takes about 30 seconds to load (also at around 100% cpu) Is this a known "feature" or am I missing

hi everybody, my samba performance is very bad. in my 100 MBit network the file transfer between nt und my samba linux (2.0.34 , 2.0.3) is terrible. from nt to nt 70 Mbytes are 2 times faster than the same 70 MBytes from Linux (i.g. samba) to nt workstation. where the hell is the problem und where can i find the solution ??? is it a problems with the passwords ?? cause all users can connect from
