SST Competition Instructions

Problem description

The research department at your company has developed a new application, but it runs terribly on their outdated hardware, so they’ve been given $3500 to purchase a new machine. As the chief computer architect, they’ve asked you to advise them on what to buy. You have received some quotes for different systems, but there are many options to pick from and each has a different cost (see table below). The company wants the most cost efficient system (highest performance per cost). You need to use SST to determine which configuration, within the budget, meets the goal of the company. To help you, the research department has modeled their workload as a Miranda workload generator subcomponent.

Instructions

1. Install SST 9.1 from www.sst-simulator.org. You will need sst-core and sst-elements.

2. Edit the Makefile in the workload/ directory so that SSTELEMSOURCE and SSTCOREINSTALL point to your sst-elements source root directory and sst-core install root directory, respectively. Then run make. You can run sst-info sc19 to check that SST can now find the new subcomponent.

3. The SST input script workload/scc-sst-node.py is parameterized to take each of the system options in the table. Comments at the top of the script describes the simulated architecture in some more detail. Do not modify the simulated architecture or workload in the script (specifying partitioning or printing additional information is OK). The script can be run as follows:

   sst scc-sst-node.py --model-options='-n=X0 -c=X1 -t=X2 -l1=X3 -l2=X4 -s=X5 -l3=X6 -b=X7 -w=X8 -m=X9'

   where the Xs should be replaced with an option from the table. For example:

   sst scc-sst-node.py --model-options='-n=40 -c=fast -t=no -l1=big -l2=small -s=private -l3=small -w=6 -b=slow -m=basic'

4. The script will immediately reject and not run any configuration that exceeds the $3500 limit with the message “ABORT: Cost exceeds limit of 3500. Cost is ...”. If the --model-options string you give is valid and within the budget, the script will print the configuration and cost, and the simulation will run.

5. A text file has been provided in this directory for you to record your answers. Fill in the configuration (--model-options string), simulated time, and cost for the highest performance/cost system (cost.txt). Correct answer (this answer is unique) receive all 35 points; incorrect answers receive up to 30 points prorated by how closely they come to the correct system. Invalid configurations, configurations that exceed the budget, and answers with an incorrect cost or simulation time will receive no points. For simulation time, include all digits and units reported by SST (e.g., “32.3187 us”).

Scoring formula for non-correct answer: $$ \begin{align*} \frac{simulated\ time_{best}*cost_{best}}{simulated\ time_{submitted}*cost_{submitted}}30 \end{align} $$
