SPEC 2017

(by Andrei Rimsa)

SPEC2017 is available in opencl@dcc. To use it, each user should install it in their own home directory (ideally) or somewhere else of his/her choice. Since every user has his own needs, it is better for each one to have a private copy of SPEC. Andrei has created a script to help with this process. The script is available at:

$ /opt/benchmarks/SPEC2017/install.sh

The script asks the user to choose a directory:

SPEC CPU2017 Installation

Top of the CPU2017 tree is '/opt/benchmarks/SPEC2017/iso'

Enter the directory you wish to install to (e.g. /usr/cpu2017)
  1) choose somewhere in your home (e.g.: /home/andrei/SPEC2017")
  2) type "yes" to continue

To use SPEC, go to you installed SPEC directory and load its configuration:

$ cd /home/andrei/SPEC2017

$ . shrc

If you wish to run the SPEC benchmarks under a simulated environment, such as valgrind, pin or any other, download and apply spec2017-prepend.patch patch. This patch adds the "--prepend" command line argument to runcpu in order to execute another program with the benchmark and its inputs as arguments.

$ patch -p1 < spec2017-prepend.patch
patching file MANIFEST
patching file bin/harness/benchmark.pm
patching file bin/harness/configpp
patching file bin/harness/parse.pl
patching file bin/harness/runcpu

The patch was designed in such a way that you can use some of the variables exposed by the running script (bin/harness/benchmark.pm). Some interesting variables are (don't forget to escape the $ while running in the terminal):

• $basedir: the directory where the simulation is being executed
• $iter: the number of the current iteration
• $workload_num: the sequence of the current input used in the iteration (it resets every iteration).

$ runcpu --prepend="valgrind -q --tool=loopgrind --cfg-outfile=\$basedir/run.cfg" --config=valgrind 557.xz
...
