FastR implements the R Language. Currently, FastR can run the R implementation of the Language Shootout Benchmarks and the Benchmark 25 suite.
This version of FastR has been published at VEE'15: "A fast abstract syntax tree interpreter for R". The project now continues here.

cd fastr-master ; ant
./r.sh
./r.sh --args 5 -f test/r/shootout/binarytrees/binarytrees.r
To run the binarytrees benchmark as shown above, FastR requires Java. All Shootout benchmarks can be run this way, but some of the mandelbrot only on Unix, as they spawn the cat
process.
To run the benchmarks from the Benchmark 25 suite, and for best performance of all benchmarks, build native glue code which links FastR to the GNU-R Math Library, system Math library, and openBLAS. The build scripts are tested on Ubuntu 13.10. Any platform supported by GNU-R and Java could be supported by FastR.

Using GNUR: yes
Using System libraries (C/M): yes
Using MKL: not available
./nr.sh -f test/r/benchmark25/perfres/b25-matfunc-1.r
To ensure that the openBLAS library is used, run the matcal-4 benchmark with the system profiler: perf record ./nr.sh -f test/r/benchmark25/perfres/b25-matcal-4.r
.
Check with perf report
that DGEMM from openBLAS is used, e.g. dgemm_kernel_SANDYBRIDGE
from libopenblas.so.0
. Also expect to see the random number generator, e.g. qnorm5
from libRmath.so.1.0.0
.
ant tests
The outputs will appear in junit
directory.
The code contains settings and project configuration for Eclipse Juno.
