qpi

At work we use SAS to manipulte large amounts of data everyday on our workstations. To give an indication of scale the largest merges we had to do was merging 24 files of 2GB in size each together into one big file (if you are familiar with SAS the files are binary compressed too!). If we upgrade our PCs to core i7 then which of Core i7 975 or Core i7 960 is better? The main difference between the two seems to be QPI. So does that affect large scale data processing such as merge datasets in SAS?

Is Infiniband going to get squeezed by iWARP and external QPI?

The Inquirer certainly thinks so.However, I'm not so sure it makes sense to compare Infiniband to an as-yet-unannounced optical external QPI. QPI is currently a processor interconnect. CPUs, RAM, and devices connected by it are conceptually part of the same machine -- they run a single OS, for example… >>> More

Core i7-860 has a slightly higher clock speed (2.8 vs 2.66 GHz) Core i7-920 has QPI and tri-channel DDR3 (vs DMI and dual-channel) >>> More
NUMA-aware placement of communication variables

For classic NUMA-aware programming I'm typically most concerned about simple cold, capacity and compulsory misses and whether we can satisfy the miss by locally connected memory or whether we have to pull the line from its home node over the coherent interconnect -- we'd like to minimize channel contention… >>> More
Wireless internet is connected to an open network but has no internet

I just installed Ubuntu on my laptop yesterday and it connected to the wireless fine. Then I took it to school, put it on their wired connection, downloaded some stuff, and now the wireless doesn't work. At first it would detect networks, but not connect. I restarted it and now it can connect, but… >>> More
