another meaningless subtitle

My new love: Python

Past Friday’s afternoon, around 3 pm, I was at university, specifically I was in one of the libraries and I was reading a book titled “Concurrency”; it’s about engineering concurrent systems using the modelling software LTSA and then write the actual program in Java. While reading I was also talking with two friends of mine about a problem another friend found on a book; to make a long story short, the problem was about balancing a predefined non-balanced random function.

AMD and LN2

Yesterday’s afternoon and today I had a LN2 trip with two AMD setup. I was aiming to break the 7 GHz wall with the trusty Phenom II 955 B.E. and improve my precedent results on socket 939 with the Opteron 148. I failed in reaching 7 GHz with the 955, tho I managed to improve just a little bit my Super-pi 1M score…still not satisfied with it but it is better than nothing.

What is the best way to kill time when you have close to nothing to do ? Easy, run Super-pi 32M using an CPU which takes more than 20 minutes to complete each run…so I did it and killed with easy 8+ hours trying to pull, tho without success, a sub 21 min 32M run with my trusty Opteron 148. Anyway, the result is still kinda worth to be posted here.

Yesterday Crucial released a new firmware for its M4 SSD series, the new version (codename 000F) is supposed to address some issues which used to appear when using the SSD connected to certain SATA/SAS controllers and generally improve stability and reliability. Changes between version 0309 and 000F include the following changes: Improved compatibility with certain SAS expanders and peripheral RAID cards. Improved throughput stability under extremely heavy workloads.

Ten days ago I had an LN2 session together with this Opteron 148; finally today I’ve the time to write a post here and talk about that. .:. SETUP: CPU: Opteron 148 cabrio @1.5*123% volt – CABYE 0536GPMW cooling: Guglio’s CPU pot 2.0 (CPU) and 1.0 (RAM) MB: DFI nForce 4 Ultra-D – bios 623-2 RAM: Corsair PC3500C2 2×256 MB :: Winbond BH-5 – yellow slots VGA: nvidia 6200 LE 256 MB PCI-E

This is the moment we are all waiting for (ok, maybe not really everyone 😀 ). Anyway, after approximately 10 hours of tweaking I came up with a quite interesting result. .:. SETUP: CPU: Opteron 148 cabrio @ 325×10.5 1.5*123 volt – CABYE 0536GPMW cooling: Single Stage phase change MB: DFI nForce 4 Ultra-D – bios 623-2 RAM: Corsair PC3500C2 2×256 MB @ 260 MHz 1.5-2-2-3 1t 3.7 volt:: Winbond BH-5 – yellow slots

Two weeks ago or so I bought a DFI nForce 4 Ultra-D, when it was here I had some fun playing with an old Athlon 64 3000+ core Winchester and some crappy DDR modules. I had also a bunch of Winbond BH-5 kits, too bad they are all dead or semi-dead, so I had to stick with a kit of Micron value PC2700 cas 2.5. Luckily a friend of mine was so glad to send me a kit of Corsair PC3500 cas 2 BH-5, so in the next few days I will have a decent kit of RAM to play with super-pi.

As you can see, it’s quite a long time since my last overclocking related post here. Even the one I’m writing now is not about overclocking, nothing of the latest hardware is interesting at all, so I don’t really bother go out and buy something. When nothing interesting is on the market the things I do is: upgrade the daily use rig. I’m not one of those interested in uber dupah performance, I’m alot more focused on reliability, so I never use the latest stuff for my DU rig…better to have 20 % less of performance but well tested and widely used components.

Think I never mentioned it but I have a small home server, it was built with a c2d E6600, an Intel G965 mobo and some HDDs. Since 2 weeks ago I was using Ubuntu then I decided it was time to try something better and more challenging than Ubuntu, my choice was CentOS. Why use CentOS ? Because it’s one of the best “enterprise class distro” with 7 years support and have a good ammount of interesting features like services GUI manager and iptables GUI.

Today I happen to read somewhere about Intel Rapid Storage and SSD performance. Well, I thought I had already installed it on my notebook but it seems I was wrong, so I did a quick google reserarch and downloaded the software from the Intel site. Someone says this software boosts SSD performance, so I did the usual ATTO benchmark to have a previous / after comparison. before after
