Hello,

Intel's High-Performance Computing Card "Xeon Phi" will released soon. This Card have a FPU-Power of 1TeraFLOP.

It looks, Xeon Phi is based on old Intel x86 Core-Design (Pentium with SIMD and AVX) with 62 cores connected with a ring-bus-system. This card have own Memory (min. 8GB)and an own LINUX-Operatingsystem which communicates with the HOST-OS via TCP/IP via PCI-Express.

Question to the Engeneerers of CPDN: Could/would it be possible to use this special HPC-Card for Climate-Modelling? Could this Card solve the problem of existing GPU-calculation for CPDN which can not run, because we need x86 compatible cores.

Bye

This card will not change what the 2 project programmers do, which is to make it possible for research groups to create climate modelling data with the programs supplied by the UK Met Office. They don't write, or re-write, these climate programs.

The closest that some advance may get would be if the resources were to be made available to work out how to get a single model to run on multiple cores of a processor and produce viable data. This was tried a few years ago, but it didn't work out, and the idea was dropped before even getting through alpha testing.

The Test4Theory@home project from CERN is multithreading, that is it runs on up to 2 cores if you want. Since it uses a Virtual Machine the CERN programs are not modified in any way and run in the BOINC_VM window.
