Abstract: [eng] [cze]
The paper describes our precious short-time opportunity to make some hands-on experience with the Bulgarian IBM Blue Gene/P system, where we tested the parallel scalability of our domain decomposition finite element solver on a greater number of processors and completed experiments with microstructure modelling of geocomposite materials. The tests showed that due to its relatively low computation/communication performance ratio this specific architecture may need optimizations of parallel codes to take advantage of its performance potential. Clanek popisuje cennou zkusenost autoru s bulharskym systemem IBM Blue Gene/P, kde na vetsim poctu procesoru testovali paralelni skalovatelnost vlastniho konecneprvkoveho resice, jenz vyuziva metody rozkladu oblasti, a take pocitali model mikrostruktury geokompozitnich materialu. Testy potvrdily, ze v dusledku relativne nizkeho pomeru vypocetniho a komunikacniho vykonu tato specificka architektura muze vyzadovat optimalizaci paralelnich kodu pro vyuziti jejiho vykonnostniho potencialu.
