SYNOPSIS
ib_clock_test
DESCRIPTION
The ib_clock_test() test utility is part of the "perftest" utilities
that are used for InfiniBand related performance testing. The
"perftest" utilities (See ib_read_lat(1), ib_write_bw_postlist(1),
ib_write_bw(1), etc.) are micro bench mark utilities. Users of the
these can use ib_clock_test(1M) to test accuracy of system clock.
The ib_clock_test(1M) utility, tests the accuracy of the system clock,
takes no parameters and provides the following output:
#ib_clock_test
