Installation Top The ZeptoOS V2.0 Kernel

Using Testcodes

Once the files installations have been done and the profiles defined by creating symbolic links to the images in the top-level directory, it is time to submit a test job. Use the test program provided with the distribution. From the top level directory: 

$ cd comm/testcodes

Compiling

The program can be compiled on the login node using: 

$ /path/to/install/bin/mpicc -o hello_world hello_world.c

Submitting Job

(For ANL Users) The job needs to be submitted using the cobalt resource manager. For the hello_world program use the following command: 

cqsub -n <number-of-processes> -t <time> -k <profile-name> ./hello_world
