The SPRINT framework. SPRINT runs across all processors. The R application (which runs the R script) runs on the master processor. This links to the SPRINT library via the R to C interface. The compute farm library uses files to communicate with compute farm which can then execute functions in the library over this compute farm. The pcor library is a parallel function library (in this case parallel correlation). Other libraries can be added, such as "hello" which is a simple "Hello World" function.
