Hello,
First of all I have to admit that I have little experience running parallel codes outside of normal SMP desktop machines, so therefore please forgive my ignorance about the way Parallella works. Before I invest any money into buying Parallella boards, I would like to know: is it possible to simply compile pre-existing scientific codes such as the VASP Quantum chemistry code on the parallella board in order to take advantage of the 16-cores Epiphany CPU, or does the code necessarily have to support GPGPU protocols such as CUDA or OpenCL to be run on the RISC cores of the Epiphany? The code I would like to use (VASP) provides Makefiles for the following architectures: Altrix, Cray, DEC, HPUX Itanium, IBM SPX, Linux Absoft compiler, Intel Fortran compiler for ITANIUM 2 systems, Linux Gfortran, Intel Fortran compiler for Pentium/Athlon/Opteron, Portland Group F90/HPF compiler, NEC SX-5, RS 6000, FUJITSU VPP, SUN, SGI and HP PA-RISC..... I normally use Linux Gfortran on Ubuntu and it works just fine. Would any of these makefiles be suitable to compile VASP on the Epiphany architecture?
Many thanks,
Gabriele
