The definitions disagree, or more than one is initialized, the There may be more than one external definition for the identifier ofĪn object, with or without the explicit use of the keyword extern if It is so common, that the C standard itself mentions it in an annotation.

This is also how I write C code and this is also how most C code I've seen has been written.īut apparently it seems that there exits a common extension to the C standard. Correct would be to just have extern declarations in the H file and matching definitions for them in one and only one C file compiled. At least when strictly following the C standard. So the behavior riscv64 is expected, the behavior on x86_64 isn't. usr/bin/ld: geo.o:/home/riscv/parsec-benchmark/ext/splash2x/apps/raytrace/obj/riscv64-linux.gcc/rt.h:750: multiple definition of `prims_in_leafs' bbox.o:/home/riscv/parsec-benchmark/ext/splash2x/apps/raytrace/obj/riscv64-linux.gcc/rt.h:750: first defined here usr/bin/ld: fbuf.o:/home/riscv/parsec-benchmark/ext/splash2x/apps/raytrace/obj/riscv64-linux.gcc/rt.h:750: multiple definition of `prims_in_leafs' bbox.o:/home/riscv/parsec-benchmark/ext/splash2x/apps/raytrace/obj/riscv64-linux.gcc/rt.h:750: first defined here usr/bin/ld: env.o:/home/riscv/parsec-benchmark/ext/splash2x/apps/raytrace/obj/riscv64-linux.gcc/rt.h:750: multiple definition of `prims_in_leafs' bbox.o:/home/riscv/parsec-benchmark/ext/splash2x/apps/raytrace/obj/riscv64-linux.gcc/rt.h:750: first defined here usr/bin/ld: cr.o:/home/riscv/parsec-benchmark/ext/splash2x/apps/raytrace/obj/riscv64-linux.gcc/rt.h:750: multiple definition of `prims_in_leafs' bbox.o:/home/riscv/parsec-benchmark/ext/splash2x/apps/raytrace/obj/riscv64-linux.gcc/rt.h:750: first defined here run-sniper -benchmarks=splash2-fft-test-4 -c gainestown run-sniper -p splash2-fft -i test -n 4 -c gainestown This distribution currently contains the following benchmark suites:

-c, -g, -s: passed to sniper/run-sniper unmodified.

-benchmarks=suitename-benchmarkname-inputsize-numcores+.

Usually test, small and large are available, as defined in our IISWC 2011 paper.

-i inputsize (required): input set name.

For Parsec, this means that the -n passed to the benchmark is usually lower since many Parsec programs start additional helper threads or use multiple threads per requested core. Note that this is the total number of threads that will run (equal to the number of available cores in the simulated machine).

-n numcores (required): number of threads to run.

-p suitename-benchmarkname (required): suite (splash2, parsec) and name (fft, blackscholes.
