I recently picked up a Supermicro X10SLL-F at Microcenter for my first DIY NAS build. I tried pairing it with the Intel Pentium G3258 (Intel Pentium 20th Anniversary Edition), thinking that it would be a robust processor.
I recently learned that it is possible to buy motherboards that support multiple CPUs. I'm curious about what the benefits of having multiple processors are. What does this enable me to do? Is it better to, for example, have two quad-core CPUs as opposed to one eight-core CPU?
To clarify: this is not a question about multiple-core processors.
Intel launched a bevy of new processors, including its highest-end desktop CPU and new, security-enhanced 32nm CPUs for the enterprise. The Xeon Processor 5600 series also includes the chipmaker's first six-core embedded processors, plus a dual-core processor for & micro servers& that has a TDP of only 30 Watts, the company says....
I have 6 PCs in my office, all running Ubuntu 12.04. The kernels that go with them are different. 64-bit CPUs (AMD) with three or more processors are 3.8.0-36-generic. 64-bit processors with a single CPU (AMD) have 3.2.0-59-generic. A PC with a 32-bit Intel CPU with two processors has 3.5.0-46 generic, and a PC with an AMD 32-bit single CPU has 3.2.0-59-generic-pae.
The forthcoming release of the GCC 4.9 compiler will feature support for Advanced Vector Extensions 512 (AVX-512) although this instruction set extension won't be appearing on Intel CPUs for a while...
"Since Intel is ramping down the motherboard business there is no plans of adding support for newer processors to the current line of boards. For new processors compatibility we recommend customers to try looking for third party manufacturers..."
