Abstract
When converting a sequential execution source program into a parallel program to be executed by respective processors (nodes) of a distributed shared memory parallel computer, a compiler computer transforms the source program to increase a processing speed of the parallel program. First, a kernel loop having a longest sequential execution time is detected in the source program. Next, a data access pattern equal to that of the kernel loop is reproduced to generate a control code to control first touch data distribution. The first touch control code generated is inserted in the parallel program.
