Compiler Technology for Blue Gene Systems
نویسندگان
چکیده
Standard compilers are incapable of fully harnessing the enormous performance potential of Blue Gene systems. To reach the leading position in the Top500 supercomputing list, IBM had to put considerable effort into coding and tuning a limited range of low-level numerical kernel routines by hand. In this paper the Vienna MAP compiler is presented, which particularly targets signal transform codes ubiquitous in compute-intensive scientific applications. Compiling Fftw code, MAP reaches as much as 80% of the optimum performance of Blue Gene systems. In an application code MAP enabled a sustained performance of 60 Tflop/s to be reached on BlueGene/L.

FFT specific compilation on IBM blue gene
Bei vielen numerischen Codes gelingt es verfügbaren Compilern nicht, das Leistungspotential moderner Prozessoren zufriedenstellend auszuschöpfen. Als Alternative zum Hand-Coding und -Tuning von numerischen Grundroutinen wurde der MAP Special-Purpose-Compiler entwickelt und speziell an die Anforderungen von Codes aus der Domäne der Signalverarbeitung angepaßt. Die neue, an IBM Blue Gene Supercom...
متن کاملA New Reporter Gene Technology: Opportunities and Perspectives
The paper summarizes the current status of the reporter gene technology and their basics. Reporter gene technology is widely used to monitor cellular events associated with gene expression and signal transduction. Based upon the splicing of transcriptional control elements to a variety of reporter genes, it “reports” the effects of a cascade of signaling events on gene expression inside cells. ...

متن کاملUnderstanding Checkpointing Overheads on Massive-Scale Systems: Analysis of the IBM Blue Gene/P System
Providing fault tolerance in high-end petascale systems, consisting of millions of hardware components and complex software stacks, is becoming an increasingly challenging task. Checkpointing continues to be the most prevalent technique for providing fault tolerance in such high-end systems. Considerable research has focussed on optimizing checkpointing; however, in practice, checkpointing stil...
