General
|
|
Is the HPC Challenge Class 2 Award partly a subjective beauty contest?
|
|
Is there a written specification of the HPC Challenge?
|
|
How big a system should I run on?
As big as you can. However, the judges do understand that the
largest machines are difficult to get time on for this kind
of activity. |
|
Are submissions in higher level languages allowed?
Yes. In fact, higher level language submissions are
strongly encouraged. |
|
Are factors other than code size (i.e. software lines of code) important?
Yes. HPC Challenge Class 2 is 50% performance and 50% elegance which includes code size, readability, required effort and expertise of the implementation. |
|
I have a very elegant approach for wrapping existing high performance parallel libraries, can I submit?
Yes. However, the judges are very interested in how your environment enables parallel computing, which includes how parallelism and data layout are expressed and used to implement HPC Challenge. |
|
Can I use serial libraries like BLAS or FFTW?
|
|
Must all relevant libraries be in the public domain?
|
|
What is code size of the HPC Challenge reference implementation?
The relevant HPC Challenge code size are as follows (approximately):
| Benchmark |
HPL |
RandomAccess |
STREAM |
FFT |
PTRANS |
DGEMM |
| Framework |

|
Must I use the HPC Challenge software framework for running my code?
No. But having similar configuration and reporting
capabilities is a plus. |
|
Are there any example submissions?
|
|
Do I have to resubmit my previous submission?
For Class 1: no (if nothing has changed in your system
since your previous submission). For Class 2: yes
(even if nothing has changed from your previous submission).
In other words, winning submission in Class 1 from previous
year is still a winning submission for this year's edition
unless a better result is submitted or the system that
achieved the winning result has changed. Last year's
winning submission for Class 2 may win this year's
competition but will not do it automatically, it has to
be resubmitted.
