1000-core MIMD Microprocessor Built

Motherboard reports on a press release by the University of California Davis, where researchers designed a multiple instruction, multiple data (MIMD) microprocessor. Unlike a GPU, each core can run distinct instructions on distinct data.

According to the researchers the chip has a greater number of cores than any other "fabricated programmable many-core [chip]," exceeding the 336 cores of the Ambric Am2045, which was produced commercially.

IBM was commissioned to fabricate the processor in 32 nm partially depleted silicon-on-insulator (PD-SOI). It is claimed that the device can "process 115 billion instructions per second while dissipating only 1.3 watts." or, when operating at greater supply voltage and clock rate, "execute 1 trillion instructions/sec while dissipating 13.1 W."

    That's not a C++ problem, that's a program organization problem. Just break the code up into a bunch of independent libraries and it will compile quickly. This also facilitates code reuse...though not as much as it logically ought to. Most of the libraries are likely to end up only being used in one project.

    That's not a C++ problem

    It usually is.

    that's a program organization problem

    Yes, C++ makes organising a program harder than many other languages.

    Just break the code up into a bunch of independent libraries and it will compile quickly.

    Interfaces are brittle in C++, which means library recompilation is often required, more so than in better-designed languages. Longer development cycle, more bugs...

    This also facilitates code reuse...though not as much as it logically ought to.

    Because C++ interfaces are complex and brittle. Templates? Exceptions? Compiler versions?

    Most of the libraries are likely to end up only being used in one project.

    Use a language with proper support for modules, no pre-processor and a proper ABI.
