Lbench
Lbench can make the following measurements
# integer-32 and floating-64 arithmetic performance
# performance of a few engineering functions (sqrt, sin, etc.)
# memory performance for cache memory and main memory
# time overhead to acquire and release a mutex lock
# time overhead to start and complete a process thread
# time overhead to start and complete a sub-process
# time overhead to call and return from a function
# disk I/O throughput for various record and file sizes
All of these functions can be run with 1-9 parallel threads. |
