LLCbench
Low Level Architectural Characterization Benchmark Suite
(LLCbench) is a suite of three different benchmark applications grouped
together in a single benchmark package. The three utilities are
MPIbench, CacheBench, and BLASBench.
MPIbench measures the performance of some critical MPI
functions. It provides performance metrics to measure the
performance of parallel computing systems and clusters running
Message-Passing Interface (MPI) applications. The second application in
this package, CacheBench, empirically determines some parameters about
an architectures memory subsystem. The third application, BLASBench, is
a useful utility to benchmark the BLAS library in relation to the
memory subsystem.

MPIbench features include:
- Packaging of datafiles for machines without GNUplot
- Automated build, execution and result processing
- Generates postscript graphs using GNUplot
- Safe from aggressive optimizating compilers
- Tunable run time parameters to reduce test domain
- Configurable cache flushing
CacheBench features include:
- Flexible data types, defaults to double instead of int
- 8 different tests, read, write and read/modify/write
- Automated build test, execution and result processing
- Generates postscript graphs using GNUplot
- Measurement of access time in nanoseconds and bandwidth in
MB/sec
- Safe from aggressive optimizing compilers
- Tunable run time parameters to reduce test domain
BLASbench features include:
- Generates graphs of UTK and vendor routines as well as
comparison graphs
- Both single and double precision data types, defaults to
double
- Formatted output to tty, tabular to file
- 3 different routines: AXPY, GEMV and GEMM
- Automated build test, execution and result processing
- Generates postscript graphs using GNUplot
- Measurement of access time in nanoseconds and bandwidth in
MB/sec
- Calibrated iteration count to maintain consistent test
length
- Safe from aggressive optimizating compilers
- Tunable run time parameters to reduce test domain
