Together with National Institute of Genetics and RIKEN, we have implemented PZLAST, a metagenomic homology search software developed on the ZettaScaler-2.0 server, on the new ZettaScaler-3.0 Server Unit.<\/strong><\/p>\r\n

 <\/p>\r\n

1.\u3000Overview and Features:<\/h2>\r\n

1) Each ZettaScaler-3.0 Server Unit (= 4 PEZY-SC3 processors) provides the equivalent processing power of 1 brick (= 32 PEZY-SC2 processors) of ZettaScaler-2.0 (Table 1 below). This eliminates the need for an immersion system and can be installed in a 4U by 19″rack.
\r\n2) The four modules of PEZY-SC3 are used in parallel to enable high-speed searches.
\r\n3) By using a large-capacity RAM (1TB) as a work area, CPU-side processing is much faster than in ZettaScaler-2.0.<\/p>\r\n

4) In addition to the speed improvement by changing from PEZY-SC2 to PEZY-SC3, various algorithms have been optimized.<\/p>\r\n

5) The metagenome database, which exceeds 2TB, is stored on an internal SSD for fast database access. This eliminates the need for external high-speed storage that was required with ZettaScaler-2.0.<\/p>\r\n

6) Parallelization with multiple computers, as done in ZettaScaler-2.0, remains effective. This system can also be scaled up by adding more computers.<\/p>\r\n
