In an earlier report, we presented the performance of several scientific applications on AIX and SUSE LINUX for the IBM eServer pSeries systems. In this report, we expand our original study by including performance analysis on the most recently announced POWER4+ family of IBM eServer pSeries systems. In our latest study, we show that the pSeries running either AIX or Linux represent a valuable combination to carry out scientific calculations in several fields. We also look at various compilers performance and provide information about the current status of Linux on POWER series.
