WebSep 10, 2013 · This tells the Cilk runtime to only use one worker, so there's only 1 thread to do the work. If you don't do this, the Cilk runtime will use as many workers as your system has logical cores - Assuming you're using Linux, the number of cores in the /proc/cpuinfo file. The environment variable is only set for the duration of the command. imb christmas offeringWebCilk (pronounced “silk”) is a C-based runtime system for multi-threaded parallel programming.
