/* _test_string4.c: test the functionality of upc_memset.

        Date created    : September 17, 2002
        Date modified   : November 19, 2002

	Function tested: upc_memset

        Description:
	- Test correctness of upc_memset() function. 
	- Each thread initializes a local array "compare[]" to be used for comparison purposes.
	- Then, upc_memset each element in "a" to VALUE+MYTHREAD.
	- Each thread performs error checking by comparing "a" to array "compare". 
	- Thread 0 determines success of test case at end.

        Platform Tested         No. Proc        Date Tested             Success
