Benchmark results for new BLAS mode
Here are the benchmark results/evaluation of the new BLAS mode as
promised. Full log files attached.
The test compares FFC default mode with FFC BLAS mode for Poisson
in 2D and 3D for q = 1, 2, ..., 8 and different levels of optimization
during the compilation with g++: -O0, -O1, -O2.
Here are some conclusions:
- Optimization (-O1, -O2) has little effect on run-time performance
in FFC default mode. These are numbers for Poisson degree 5 in 3D:
| Run-time | Compile-time (g++)
------------------------------------
-O0 | 3.417e-05 | 4.596e+00
-O1 | 3.116e-05 | 5.725e+01
-O2 | 3.788e-05 | 6.929e+01
With -O1, the code runs about 10% faster and with -02, the code
is actually slower, possibly due to increase in size of object code.
On the other hand, the level of optimization has quite a big
influence on the compile-time (g++). Compile-time increases with
more than a factor 10 when going from -O0 to -O1 and even more when
going to -O2.
Compiling with optimization also increases the memory usage for g++
and I can't go beyond q = 5 for Poisson on my 2GB machine with -O2
and g++ 4.0.2.
Conclusion: -O1 may improve the run-time performance, but only
little and with a big penalty in compile-time.
- Optimization (-O1, -O2) has no effect on run-time performance in
BLAS mode, at least not for Poisson, where the computation of the
geometry tensor is only a small contribution to the overall work.
These are numbers for Poisson degree 5 in 3D:
| Run-time | Compile-time (g++)
------------------------------------
-O0 | 6.787e-05 | 1.070e+00
-O1 | 6.817e-05 | 1.305e+00
-O2 | 6.805e-05 | 1.448e+00
Also note that compile-time (g++) is much the same with different
levels of optimizations in BLAS mode.
Conclusion: the level of optimization has little effect in BLAS
mode.
- Comparing now FFC default mode with FFC BLAS mode, we have the
following timings for Poisson degree 8 in 3D:
| BLAS mode | default MODE
-----------------------------------
FFC | 6.039e+01 | 6.807e+01
g++ | 1.383e+00 | 9.053e+01
Run-time | 5.907e-04 | 1.333e-03
Compile-time with FFC is about 1 minute in both modes.
Compile-time with g++ is a factor 6 better in BLAS mode.
Run-time is more than a factor 2 better in BLAS mode.
When examining the influence of the order q, one finds that BLAS
mode is always equal or faster than default mode in terms of g++
compile-time. In 3D, the difference is significant for q > 3.
Concerning run-time performance, FFC default mode is faster than
BLAS mode for small q, and BLAS is faster for large q. For Poisson
in 3D, the break-even point is at q = 6.
Conclusion: the FFC blas mode will in some cases generate faster
code, but it's first and foremost an option that should be
considered to decrease the compile-time (with g++).
- Overall conclusions:
It's unecessary to compile with -O1 or -O2. We have -O2 by
default in DOLFIN, but should probably consider to change to
-O0, at least for the compilation of forms. There is probably
a huge improvement in compile-time for Navier-Stokes if we switch
to -O0.
BLAS can be an option to reduce compile-time and possibly to
improve the run-time for high-order forms.
- Finally, note that these benchmarks are for Poisson, where the main
part of the work is the computation of the element tensor (doing the
tensor product). For other forms, computing the geometry tensor can
dominate, and then BLAS mode won't help, but compiling with -O0 may.
