Blir mer og mer overbevist om at opeteron/athlon64 er det neste systemet mitt.

 

Bare og bli litt mer brukbar i C++ nå da

Kjempe bra..

Men hva er "kompilatorer"

Har hørt det før men ikke fått med meg hva det er for noe..

kompilator:

--------------

 

et program som oversetter programmeringskode som er skrevet i noe forståelig engelsk (eks c/c++) til kode som datamaskinen skjønner på binært nivå, 1 og 0 (av og på)

 

 

dagens kompilatorer brukes i sammenheng med å lage .exe filer, eller kjørbare filer.

PathScale fortsetter å imponere og har nå øket ytelsen med nesten 30% i SPEC-tester på Opteron:

Sun tested 2-way Sun Fire V20z and 4-way Sun Fire V40z servers using multiple SPEC benchmarks, including the SPEC® ompM2001 suite of OpenMP® benchmarks. The PathScale EKOPath Compiler Suite helped Sun's AMD® Opteron® processor-based servers set world records for SPEC ompM2001 on two-processor and four-processor systems. The Sun/PathScale two-processor results were 29 percent faster (footnote 1) than previous-best Linux ompM2001 benchmarks using non-PathScale Fortran and C compilers. This 29 percent advantage, enabled in large part by PathScale compilers, far exceeds the eight percent faster clock rate of the newer Sun systems. The Sun/PathScale four-processor SPEC ompM2001 result surpasses the best four-processor benchmarks on Intel Itanium 2, Power5 and Alpha processors as well as previous SPEC results on four-processor Opteron systems.

 

In addition, using the SPEC® CPU2000 benchmark, the Sun Fire V40z server equipped with the PathScale EKOPath Compiler Suite achieved two new world records for 4-way x86 systems on integer and floating point performance (footnote 2). The V20z server achieved a new x86 world record score on floating point intensive SPECfp2000 performance, as well as the best 2-way x86 result on floating point performance. The PathScale-optimized Sun servers showed improved scalability and higher performance for both floating point and integer performance, with up to 25 percent improvement when compared with previous benchmarks.

 

"Sun's choice of the PathScale EKOPath compilers over all other compiler alternatives is a testimony to the clear performance advantages of PathScale compilers and our new OpenMP 2.0 implementation," explained Art Goldberg, COO of PathScale. "We have made some major improvements in the EKOPath 2.0 release to optimize performance of multi-processor nodes and have also worked closely with AMD to support their upcoming dual-core processor release. OpenMP performance is critical to efficient use of these types of systems and the Sun benchmark results underscore the quality of the EKOPath implementation."

 

(1) About the SPEC OMPM2001 Results Reported Above:

 

Two-Processor Results: The Sun V40z server with PathScale EKOPath Compiler Suite and 2.6 GHz AMD Opteron CPUs achieved a result of 6486 on a system with two cores, two chips and two threads. This comparison is based on the best performing two-processor servers currently shipping by IBM [sPECompM2001 5526, two cores, one chip, four threads] and Suns previous results with competitor's compiler on a 2.4 GHz Java Workstation W2100z system [sPECompM2001 5085, two cores, two chips, two threads].

 

Four-Processor Results: The Sun V40z server with PathScale EKOPath Compiler Suite and 2.6 GHz AMD Opteron CPUs achieved a result of 11223 on a system with four cores, four chips and four threads. This comparison is based on the best performing four-processor servers currently shipping by IBM [sPECompM2001 10522, four cores, two chips, eight threads], HP with Alpha CPUs [sPECompM2001 6946, four cores, four chips, four threads], HP with Intel Itanium two CPUs [sPECompM2001 6886, four cores, four chips, four threads], and Sun V40z previous results on a 2.4 GHz system with a non-PathScale compiler [sPECompM2001 8694, four cores, four chips, four threads].

Forspranget til Itanium på SPECfp-testene er nå kraftig innhentet, og Opteron har faktisk forbigått den i noen tester
