I want more control because the Windows thread scheduler seems to bounce around threads for no reason. If I make it multithreaded, then I am at the mercy of whatever crazy algorithms have been programmed into the scheduler. I believe Windows round robins the thread across the cores as an element of...

#pragma omp parallel for and compile your C/C++ program with -fopenmp on a modern compiler. Place that #pragma directly above any for() loop and the compiler will automatically optimize the loop to use all possible cores. This is a starting point. Look up OpenMP for more. Its incredibly simple and ...

That's about right as far as performance goes. TR has benchmarks on the drive which are pretty close. Realigining partitions is a waste of time and I doubt would offer any notable performance increases. http://techreport.com/articles.x/22401/4 An un-aligned partition can cause all IO to double. eg ...

Just use DD from any Linux live CD to do a raw byte-for-byte copy. You *should* be just fine with a drive of equal or larger size. The offset should be based from the beginning of the disk, so a larger disk should not affect anything.

Every CPU of which I am aware, even little microcontrollers, have to capability to provide some sort of hardware counter. In x86 compatible CPUs this is a free-running tick counter. As the OS enters a running task, it notes the value of that counter, and again when it comes out of that task back in...

So how does Windows figure out the CPU utilization and what does that even mean? I'm a computer architecture and VLSI design student so I know how a CPU works and I can't figure out how you would ever get to 100% CPU utilization on a consistent basis. It seems that branch mispredicts (as rare as th...

My home router supports jumbo frames on the switch. It's a dumb switch, so I can't turn it off.

Celeron 300a. Had a 100mhz bus, but the BX chipset was crazy stable and could OC to 133mhz. Insta 450mhz cpu when they were expensive. Also, it had on-die cache, even though less, so many times i twas faster than the 450mhz sibling that had more, but 1/2 speed off-die L2.

Bulldozer won't be competing with 32nm Sandy Bridge except for just a little bit. 32nm BD will primarily be competing with 22 Ivy Bridge, which can pack 50% more transistors. Intel is going 14nm in 2013. By the time BD gets its 28nm shrink, it will be up against a 14nm chip, packing about 75% more t...

I'm hoping for BD to be competitive, but I have a feeling Ivy Bridge is going to be a power house. IB at 22nm will be released shortly after BD at 32nm will be. That being said, an octal-core(quad module) BD chip should be more than enough power for even an avid gamer. Only SQL/Web/Video people will...

The larger the cache, the higher the latency. If they made 256k of L1 cache, not only would it eat up more transistors, but it could over double the latency, which would hurt performance. It's a delicate balance between locality and latency. Prefetching and hyper threading can help mask a lot of sta...

Add me in.

I just go all out and use SHA512 with a random GUID for a salt. Good luck rainbow-tabling that. A Rainbow table attack just uses a list of know hashes as a "hash table" lookup. By adding a salt, you invalidate all the entries in the rainbow table, so the table would have to be re-computed ...

QQ why won't Blizz protect me from myself?! It's their responsibility! Join a forum and right away act like a tool. Using "QQ" -- what, are you 12? Also, good job ignoring the points in Vinceant's post. Sorry, 5 years of WoW and people complaining about the same issue that has ALWAYS been...

/sigh Don't complain if your hacked because you didn't dish out the $6.50 for the authenticator. btw, that includes s/h and the devices cost $14 whole sale so Blizzard is not only saving you $7.50, but they're covering the S/H. The hackers have been known to circumvent the authenticators. The only ...

Assuming the computer are in the same broadcast domain, he could setup a service to run on both machines. Using raw packets, he could construct his own Layer3 generic protocol and just send his custom data packet to the MAC address. When the other system's service sees this specific type of packet, ...

I have an APC1500va UPS that I bought back in 2001 and I'm still using the original battery. Anyway, it claims the battery is bad but my i7-920(stock) 4GB ram, 22" LCD, and ATI4850 still gets a good 10min of run time on it. As for AVR, yeah it has that, but I'm not sure how crazy important it i...
