Re: [ccp4bb] MX data processing with GPUs??

Dear Ana, To benefit from GPU architecture, over CPU, the algorithm needs to do quite significant number crunching – i.e. do at least certain number of floating point operations (FLOP) per one byte of data. It also needs to be highly parallel, preferably without conditional (if/else) statements

Dear Aleix, From what you say, it is also possible, that you see anomalous scattering of native elements present in your complex - your DNA contains P atoms, there might be also S in protein part and K+/Ca2+ in solvent. The signal is very weak at 12667 keV, but could give high anomalous correla
