RaftLib is a portable parallel processing system that aims to provide extreme performance while increasing programmer productivity. It enables a programmer to assemble a massively parallel program (both local and distributed) using simple iostream-like operators. RaftLib handles threading, memory allocation, memory placement, and auto-parallelization of compute kernels. It enables applications to be constructed from chains of compute kernels forming a task and pipeline parallel compute graph. Programs are authored in C++ (although other language bindings are planned).
Example Here is a Hello World example for demonstration purposes:
import <raft>; import <raftio>;
import std;
using String = std::string;
using RaftKernel = raft::kernel; using RaftKernelStatus = raft::kstatus; using RaftMap = raft::map; using RaftPrint = raft::print;
class HelloWorld : public RaftKernel { public: HelloWorld() { output.addPort<String>("0");
virtual RaftKernelStatus run() { output["0"].push("Hello World\n"); return raft::stop;
int main(int argc, char* argv[]) { // instantiate print kernel RaftPrint<String> p;
// instantiate hello world kernel HelloWorld hello;
// make a map object RaftMap m;
// add kernels to map, both hello and p are executed concurrently m += hello >> p;
// execute the map m.exe();
return 0; }
