Dear all,
We are putting new simulations in DENIS (in the CRLP2011 app). These first simulations will be in small groups and little by little the groups will increase in size.

Thank you for your patient!

Best regards,
Jesús.

Great news! I take a few task to see how it runs.

Hope there start for real after this summer.

Any chances to get optimizations included in the app ? WUs seem so slow ...

Yep. I will try to do some optimizations in free time.

FIrst I have to look in new source(models).

Hi!
We will try to add some of them to the official version in a near future. But the main limitation is that we never work directly with the code of the models. We use CellML files with the description of the models and we export them by using a tool we have developed: https://github.com/DENISproject/DENIS-CellML2C
We need to modify this program to make them automatically.

Best,
Jesús.

Did you even enable automatic optimization (SSE x.x or AVX) when compiling the application to embed all code path in the same executable ?

They compiled with mtune=generic and march=x86_64, so the compiler assumes that it can use either x87 instructions or SSE2. There is lots of x87 code.

They use the GNU 4.8.1 compiler so they would have to build special CPU specific binaries to support AVX.

The execution profile indicates that the code does not generate VECTOR instructions so AVX2 would probably generate slower code because of the larger data footprint.
