1. Is it possible to replace team members after submission?

–  yes

2. Is it possible to have more than 6 people in the group?

–  The submission proposal can have more than 6 members, but for the competition only 6 team members can compete.

3. Can the HPL binary from the HPCC application can be substituted by the NVIDIA optimized binary?

– It’s possible, and may help to the utilized better the GPUs for HPCC. However, we need to understand the exact code changes, to make sure it is valid.

4. We would like to implement an optimization on the HPCG. With the OptimizeProblem() it is possible to allocate memory only at the beginning of the problem, however, it is not possible to do any memory management at the beginning and end of every CG iteration. Are we allowed to modify CG.cpp for this purpose? (algorithm remains the same)

– Yes we allow changes to the code for various reasons. Sometimes if the group has some special hardware (like GPU) and they want to offload the compute intensive routine for their hardware, the team can work on making changes to the code instead of using the reference implementation, as long as their implementation doesn’t change the logic of the application/algorithm. In your case, it seems to be ok.

In any case, you will need to show us the changes of the code so we could review, and supply description of the changes to help us with that.

5. Can I use any version of TensorFlow?

– Any general available version can be used, changes can be done. The differences/patches done should be sent to us for review.

6. Can we get formal invitation letter from the competition, we need it in order to get the VISA to Germany.

– Yes, please email us and we will generate it for you.

7.  As for HPCC – is there a limit for how much code allowable to be optimised? (We can demonstrate that we didn’t change the algorithm)

– For code change you will need to show us your modifications in HPCC/other codes, we will need to review the changes and evaluate.

8. May I know if all nodes are required to participates in benchmarking? We can have the all nodes connected to power supply, and will not change the hardware configuration after benchmarking.

– For hardware, after submitting the first set of results, that would be the hardware they would need to use throughout the competition. Such that if you use 8 nodes in the first submission (say for LINPACK), they will need to keep using 8 nodes throughout even if you use less, or want to use more/others.

9. What can I expect regarding students accommodation, meals, etc.?

– We don’t supply accomodation for the students, you will need to work this out your own. Meals may be provided during the competition.
