On behalf of a friend i'm building a pc to run his algos although im not sure which route to take. this is his statement:
Hi,
I'm torn between these two processors at the moment. The programs i run in matlab dont run in parallel until certain simulations at which point they will use all 6 or eight cores for certain simulations. in terms of time about 80% will be spend using all cores.
I can liquid cool and overclock the i7 to 4.5 however i need to run this every day for 8 hours for about a year. so i'm worried this will cause problems.
The e5-2687w v2 whilst it has more cores has a lower clock speed and the turbo boost is 4ghz but i dont know how long it can sustain this.
Whats my best option ignoring price etc other components will match, 2400mhz ram 32gb, ssd in raid 1 etc.
I'm looking at executing the code as fast as possible - is my main goal.

On anything this computationally massive, almost always the best bang will be achieved by making a serious effort at optimizing the code. After all, if it will take a year to solve, why not invest a few days of programming time, if that will give even a 20% decrease in the time required? Surely this is worth the effort. Since the profile tool can help to identify the bottlenecks in the code, it is the perfect tool to find those few points where the time will be well spent.
