The Chinese reclaimed the top spot on June's 'Top500' fastest supercomputers list with a system almost twice as fast as any other.
Juqueen is the most powerful European supercomputer. Peaking at the speed of about 5 petaflops, it moved down two spots since November's "Top500 List" to No. 7 on the June list.
Different versions of the system, which have been manufactured by IBM (IBM), have also cracked the top 10 in the past.
Juqueen is housed at the Forschungszentrum Juelich research center in Germany. It is one of 19 supercomputers located in Germany that made the Top500. The United Kingdom and France have 29 and 23 systems, respectively, on the list.
