[Tutor] Threads, ok to access parent script methods by passing 'self' ?

Hi All, If a thread is started and 'self' is passed as a parameter, is it acceptable to access methods of the calling class via 'self.updateGrid()' etc from within the thread or does everything have to be done via wx.lib.pubsub and publisher calls ? Cheers Dave -- Please avoid sending

[Tutor] Threads and Signals

Hi, I am testing out some stuff with threads and signals. This is just a prototype of how I want to incorporate it into my main script. I figured out how to catch signals for SIGUSR1 to output what all the thread children are working on. The problem I have is if in terminalA I run my script,

I just looked at web.py. It's not a webserver. It's a toolkit you use to write your own webserver. Why are you under the impression that it's a webserver? Did you just google for 'web server in Python' and find this? you are right, i mean that it is the core of the webserver If you're

I have done scripts for decompressing MP3 in the past. I normally follow a fork() exec() subprocess scheme, and this helps me gain about 30% improvement. I'm not an expert, but I have read that CPU time will be better used by several processes than for just one, and while one process is

I knew what he meant, but since most albums have around 12 tracks, 4 tracks per thread gives you 3 threads. In any case, thanks for the catch on the loop. I'll let you know if it makes a difference.On 10/22/05, Kent Johnson [EMAIL PROTECTED] wrote: Alan means to use two or three threads

Re: [Tutor] : Threads?

in mind, I thought, why not try to use threads so all the conversions happen simultaneously? That way, the whole album will take between 30 and 50 seconds. One possible problem with this is that the activity is disk IO bound. In fact using too many threads could even slow the thing down

Re: [Tutor] : Threads?

I'll try doing 3 or 4 tracks per thread, then. Thanks for the advice.If you keep the thread count down to two or three you might get a noticable improvement but one thread per track, unless you havea lot of separate hard disk spindles to distribute the work willnot help much I suspect.Alan G. --

Re: [Tutor] threads

If what you want is something that scales up, then you're attacking the Wrong Problem. Rather than focus on getting your thread overhead as small as possible in order to support as much real-time concurrency as you can, you should (as has been suggested) try to get simulation-time concurrency

I have run into a problem again. I thought about simulation time concurrency and figured an inherent problem with the approach. The main objective of my project is to simulate traffic behavious under congested conditions.Hence I was using semaphores to lock the areas already occupied by the

Re: [Tutor] threads

Remember that I am generating cars even while the simulation is running, hence calculating this HCF at the beginning is not going to work. Any comments? This won't help you much in writing your program, but you might find it interesting and vaguely similar to what you're doing:
