Google crafts custom networking CPU with parallel computing links
Updated It appears Google has quietly built an in-house processor with close ties to parallel computing and networking. Evidence of the CPU, destined for internal use only, emerged today in source code patches for the LLVM C/C++ compiler, allowing programmers to produce executables for the hardware. Not that you can get your hands on any. Getting the patches accepted into LLVM, though, will make l
Writing fast, processor-independent code using C++ and LLVM bitcode
Writing fast, processor-independent code using C++ and LLVM bitcode Using inline assembly along with C/C++ code has long been the best choice for developers writing optimized code. However the approach had its shortcomings: - the need to write assembly for each architecture - the use of inline assembly hinders certain compiler optimizations (such as register allocation) But thanks to LLVM it is no

%0 = add i32 %X, %X ; yields i32:%0 %1 = add i32 %0, %0 /* yields i32:%1 */ %result = add i32 %1, %1 This last way of multiplying %X by 8 illustrates several important lexical features of LLVM: Comments are delimited with a ‘;’ and go until the end of line. Alternatively, comments can start with /* and terminate with */. Unnamed temporaries are created when the result of a computation is not assig
The Julia Programming Language
Fast Julia was designed for high performance. Julia programs automatically compile to efficient native code via LLVM, and support multiple platforms. Dynamic Julia is dynamically typed, feels like a scripting language, and has good support for interactive use, but can also optionally be separately compiled. Reproducible Reproducible environments make it possible to recreate the same Julia environm
