[petsc-dev] OT: Testers needed for PathScale ENZO 2012

["C. Bergström"]

Hi

I'm hoping someone with some spare cycles and patience is willing to 
help test a nightly ENZO build with petsc.

Here's the nightly which won't require a key (It will ask, but it's 
optional)
http://c591116.r16.cf2.rackcdn.com/enzo/nightly/Linux/enzo-2012-09-18-installer.run

For BLAS we're testing against this (and in the future will ship our own 
built version)
https://github.com/xianyi/OpenBLAS/
----------
I'm specifically looking for feedback on the GPGPU side of this and 
performance.  The reason why anyone would care - We've put a lot of work 
in performance for memory bound kernels, predictable latency and lowest 
latency.  (We don't generate any PTX and go direct to bare metal codegen 
tied with our own very small runtime.  We officially only support Tesla 
2050/2070 cards at this time, but ping me if you have another card you 
can test with)

You can replace nvcc with pathcu (We don't support the nvcc flags)

pathcu -c foo.cu # CUDA (Bugs found should be fixed quickly, but expect 
bugs - Thrust and CuSP testing also in progress)
pathcc/f90 -hmpp # OpenHMPP
pathcc/f90 -openacc # OpenACC and the flag will be changed to -acc soon

For more details, documentation and or bug reports please email me directly.

Cheers,


Christopher
