Recommendation Report for the Next-Generation Computer Resources (NGCR) Operating Systems Interface Standard Baseline
Abstract
The Next-Generation Computer Resources (NGCR) Operating Systems Standards Working Group (OSSWG) conducted a survey of existing operating systems and operating systems interface standards to establish a baseline for the NGCR operating system interface (OSIF). As a result of this survey, the total number of operating systems considered was reduced from 110 to 7, which then were formally evaluated. These seven were Alpha, ARTX, CRONUS, iRMX, Mach, ORKID, and POSIX. The formal evaluation consisted of assessing the seven candidates against the requirements contained in the NGCR OSSWG Requirements Document (reference 1) and a set of eight programmatic issues. The numeric results of this evaluation identified three candidates as superior: Alpha, iRMX, POSIX. To obtain a clear consensus of the OSSWG, an anonymous ballot was held that resulted in POSIX obtaining a 51-percent majority vote. Based on the results of the balloting, the NGCR OSSWG recommends POSIX be selected as the NGCR OSIF baseline. The working group also recommends that the Navy and OSSWG capitalize on the strengths of the other candidates, particularly Alpha and iRMX, in the continuing standards development.
