Installation
Follow the "Tools" link from the Downloads menu at the SimpleScalar web site to download the package with the SimpleScalar source code. The file that you need to download is simplesim-3v0d.tgz. You need to agree to SimpleScalar terms of usage prior to downloading the file.
Copy this file to the Grid appliance, under /home/griduser, using one of the mechanisms (sftp or Samba) described in the Grid appliance introductory tutorial.
Uncompress and compile SimpleScalar with the following commands within the appliance (these will compile the PISA version of SimpleScalar; at this time the Alpha model does not compile correctly with the version of gcc within the appliance):
cd tar -xzf simplesim-3v0d.tgz cd simplesim-3.0 make config-pisa make
Test the SimpleScalar installation with the following commands:
cd tests-pisa make do-tests DIFF=/usr/bin/diff ENDIAN=little SIM_DIR=/home/griduser/simplesim-3.0/ SIM_BIN=sim-outorder cd results diff anagram.progout ../output/anagram.progout
The output of the diff command should be blank - meaning there is no difference between the output generated by your SimpleScalar and the reference output that comes with the simplesim-3v0d.tgz package.
Condor simulation
Here is a sample Condor submission script for one of the SimpleScalar tests. Type in and save this as a file named simplescalar_submit within the /home/gridusers/simplesim-3.0 directory:
Universe = vanilla Executable = sim-outorder Log = montepi.$(Cluster).$(Process).log Output = simoutorder.$(Cluster).$(Process).out Error = simoutorder.$(Cluster).$(Process).err should_transfer_files = YES transfer_input_files = tests-pisa/bin.little/anagram, tests-pisa/inputs/words when_to_transfer_output = ON_EXIT Arguments = -redir:prog anagram.progout -redir:sim anagram.simout anagram words Queue
This example submits the sim-outorder model with the anagram application and the words input file. The outputs of this run will be stored in the anagram.progout (stdout of the anagram program) and anagram.simout (simplescalar stdout).
Future Work
- We need to find out how to compile the Alpha model with the gcc version within the appliance. If you know how to do this, feel free to add instructions to this document.
