RTK(RunTime in Kernel)

This is the top-level git repository for the Run time in Kernel(RTK)

Different branches include different things we built described as below, and in README of different branch, detailed description on how to use and what to test is provided (except for PIK, CCK, which are supposed to appear on other repo)

Branch	content
OpenMP	OpenMP library source code, able to compile OpenMP library
LibOMP	Compiled OpenMP library
RTK	Runtime in Kernel, and benchmarks run with kernel
EPCC	EPCC benchmarks source code for linux
NPB3.0-omp-c	NAS-NPB source code for linux

Alternatively, even without going to each branch, we provide top-level make command that will compile different things.

Fetch EPCC, NAS Parallel Benchmarks (NPB), and RTK source code

Run from the top directory

make init

Nautilus with EPCC Benchmarks

Build Nautilus with EPCC Benchmarks

make BENCH-NAME=EPCC build_nautilus

Run EPCC Benchmarks from within Nautilus (on QEMU)

make run_nautilus BENCH-NAME=EPCC

To start running benchmarks, use the following commands at the root-shell prompt:

root-shell> ompb

To test on a physical machine, write the nautilus_rtk/nautilus.iso to a CD or USB stick and boot the machine. Alternatively, add nautilus_rtk/nautilus.bin to your grub configuration as described elsewhere, or PXE boot it.

Nautilus with NAS Parallel Benchmarks (NPB)

Build Nautilus with NPB

We included eight of NAParallel BenchmarkS Parallel Benchmarks (BT, FT, CG, EP, LU, MG, IS, SP) in RTK. FT is used as an example below:

To build Nautilus with one NAS Parallel Benchmark (e.g. FT), use the following command:

make build_nautilus BENCH-NAME=NAS BENCHMARK=FT 

Run NPB from within Nautilus (on QEMU)

note, to quit from qemu, use "Alt+2", then type "quit"

make run_nautilus BENCH-NAME=NAS BENCHMARK=FT 

To start running that benchmark (e.g. FT), use the following commands at the root-shell prompt:

root-shell> nas-ft

To change the number of threads, for example to 16 threads, before running the test, run following:

root-shell> omp_num_threads 16

Or

root-shell> set-omp-num-threads 16

Compile and Run Benchmarks on Linux

To compile the same test suite as RTK's:

make build_linux

This will compile BT, FT in B Class; CG, EP, MG, LU, IS, SP in C Class for NPB; this will also compile all the EPCC Benchmarks.

To run them all:

make run_linux

WARNING: This would take hours to finish.

---

EPCC benchmarks

To compile EPCC benchmarks for Linux:

make build_linux_epcc

To run all the EPCC benchmarks:

make run_linux_epcc	

---

To run one of the EPCC benchmarks (syncbench, schedbench, taskbench, arraybench_59049), run the following: (e.g. arraybench_59049)

make run_linux_epcc BENCHMARK=arraybench_59049

---

NAS Parallel Benchmarks (NPB)

To compile the same test suite as RTK/CCK's:

make build_linux_nas

To run this test suite:

make run_linux_nas

WARNING: This would take hours to finish.

---

All available NAS Parallel Benchmarks include FT, CG, BT, LU, IS, EP, SP, MG available at 4 scales/classes (S, A, B, C)

To compile a specific NAS Parallel Benchmark (e.g. FT) with CLASS B, run following:

make build_linux_nas BENCHMARK=FT CLASS=B

To run a specific NAS Parallel Benchmark (e.g. FT) with CLASS B after build:

make run_linux_nas BENCHMARK=FT CLASS=B

---

If you want to compile a different test suite with different CLASSes from the test suite we are using for the paper, do the following:

vi linux_npb-nas/config/suite.def	

and uncomment the benchmarks you want to include in the test suite for Linux.
