clwprime is a program for solving if p is a prime or not by using Wilson's theorem. It solves it with parallel computation. Reducing the time complexity for bigger p than if it were to be computed with serial computation. This program works similar to the wprime program. The Differences is that it solves the prime in serial computation.
- Check if 13 is prime. Returns 1 if true or 0 if false.
clwprime 13
- Check if 13 is prime. Will print the result in a human readable format.
clwprime 13 -h
- Check if piped 13 is prime.
echo '13' | clwprime
In order to compile the program, the following Debian packages has to be installed.
apt-get install opencl-headersBecause each graphic card vendor has their own driver for implementing OpenCL. You'll have check what packets has to be installed for the graphic cards on host in order for the OpenCL work on the system.
The clinfo programmed can be installed with apt-get. It will display information about each OpenCL compatible devices on the host. If no information is displayed, then either there is not OpenCL compatible devices or the driver is not installed properly.
