Re: nvidia and latest unstable kernel image
I am on debian lenny amd64 shipped with an nvidia GeForce 6150, with 2.6.24 release I had no problem running nv driver, now I am 2.6.25 using nvidia proprietary driver with no problem at all. Dual head works fine too. I just followed this brief but operative how-to http://tinyplanet.ca/~lsorense/debian/debian-nvidia-dri-howto.html hope this helps 2008/7/15 Seb [EMAIL PROTECTED]: Hi, I still cannot use the new 2.6.25 kernel due to this problem with nvidia module, even with the recently available linux-headers-2.6.25-2-amd64 and image packages. I'm starting to think that these don't work with my card anymore. If anybody has any further tips, I'd be grateful for them. Thanks.

EM64T compiling options?
Hi, I'm migrating from an i686 to an EM64T machine (Intel core 2 quad) and I'd like to know whether there are specific options that I can pass to gcc for an optimization of my code or if everything is blindly set up. How would I manage the 4 cpu cores if I was to write in assembly? Thank you in advance for any link or information on this subject.

How would I manage the 4 cpu cores if I was to write in assembly? GCC has a lot of optimization/architecture flags. Just have a look here [1]. However, this won't make your software use the 4 cores. You should use threads or multiple processes with IPC. I don't know what you want to do but I think you should forget about writing in assembly and use an higher level language. You probably don't need assembly at all. Moreover, higher level language have sometimes concurrency and synchronization facilities which will help you getting the most of your 4 cores.

Re: EM64T compiling options?
Many thanks, I'll read your link with attention. Do you have further links on threads and IPC ? I'm thinking in rewriting an old and unfinished logical interpreter in C that used assembly code (nasm) for truth evaluation of the smallest elements. I'd like also to create a small database for prime numbers (using John Moyer's storage code) in order to test several things on prime numbers distribution.

You might write a critical section of code in assembly, but all the glue ought to be in C, inluding anything to manage pthreads to do multiple threads, which is how you take advantage of multiple cores. As for optimizing, there really aren't any options yet since there are very few amd64 designs so far and they all have the same instruction set and features pretty much and hence the code should be pretty much optimal for all of them (in as much as gcc produces optimal code for anything). -- Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Opera 9.51
Hi, everyone, I have Opera 9.51 (amd64 version) installed here, but it is unusable. It starts without error, and I can usually browse a page or two, but then it stalls, or at least becomes hideously slow. If I run top and then start Opera, it's CPU usage climbs to near 100% and the memory percentage seems to increase slowly as long as it is open. This doesn't happen with the 32-bit version that I have installed at home. Does anyone have an idea as to what's going on here? -Chris | Christopher Judd, Ph. D.

AFAIK it use pthread to work but it create all necessary pthread at startup to avoid creating them at each loop parallelization. It should work properly with pthreads, it wouldn't be packaged with gcc if it wasn't the case. However I didn't test this combination. openmp is really simple to use, easier than programming the same thing with pthreads. You can see examples on wikipedia : http://en.wikipedia.org/wiki/OpenMP The purpose is to do simple parallelization.

Re: EM64T compiling options?
There is an environment variable GOMP_AFFINITY in libgomp that binds threads to single cpus. Can I use it the same way with multi-cores (i.e GOMP_CPU_AFFINITY=0 1 2 3 in order to bind thread 1 to core 0 etc..)? Is this a good way to take advantage of the quad architecture?

hibernate, just a question
Hi all, I am using swsusp with hibernate. In the past I had the problem, when hibernate started, only hibernate-ram was working. Using hibernate-disk ( same as /usr/bin/hibernate), the contents of the memory was not written to disk. So it failed. Now I am wanderin, although I never changed the configuration and never changed the version of hibernate, suddenly it is working. So, glad everything is fine now, the situuation is not really satisfying, as I want to know, why it is working now. Maybe someone is knowing more. Was there something known in the past about it ? (there was a bugreport by me) Or have there been some changes to the kernel relating to this ? I would be pleased about every information, to learn what happened !
