The S/390 G5/G6 binodal

چکیده
The IBM S/390 fifth-generation CMOS-based server (more commonly known as the G5) produced a dramatic improvement in system-level performance in comparison with its predecessor, the G4. Much of this improvement can be attributed to an innovative approach to the cache and memory hierarchy: the binodal cache architecture. This design features shared caching and very high sustainable bandwidths at all points in the system. It contains several innovations in managing shared data, in maintaining high bandwidths at critical points in the system, and in sustaining high performance with unparalleled fault tolerance and recovery capabilities. This paper addresses several of these key features as they are implemented in the S/390 G5 server and its successor, the S/390 G6 server.

The CMOS-based IBM S/390 Parallel Enterprise Servers have always employed the technique of memory caching to bridge the gap between processor speed and mainmemory access time. However, that gap has widened with each succeeding system generation, requiring increasingly sophisticated, multiple-level cache structures in order to minimize memory-access latency. The IBM S/390 G5 and G6 include two-l...

This study aimed to evaluate the quimiopreventive ability of phenylalanine. We used pregnant and non-pregnant female mice divided into the following groups: G1-PBS, (0.1 mL/kg b.w); G2, cyclophosphamide (35 mg/kg p.c.-i.p.); G3 and G4, phenylalanine (150 and 300 mg/kg b.w respectively-v.o.) and G5 and G6, association between the two doses of phenylalanine and cyclophosphamide, respectively. The...
