TEST (global output) HPL_T_test * On entry, TEST points to a testing data structure. On exit, the fields of this data structure are initialized as follows: TEST->outfp specifies the output file where the results will be printed. It is only defined and used by the process 0 of the grid. TEST->thrsh specifies the threshhold value for the test ratio. TEST->epsil is the relative machine precision of the distributed computer. Finally the test counters, kfail, kpass, kskip, ktest are initialized to zero.
