Gradient Technologies Inc, of Marlborough, Massachusetts is irked at longtime rival Globetrotter Software Inc, Campbell, California for getting Silicon Graphics Inc to dump its NetLS software in favour of Globetrotter’s Flexlm software licence manager, a fact that Silicon Graphics and Globetrotter reportedly neglected to mention to Gradient before press releases were sent. Globetrotter sees it as just one software vendor supplanting another, but Gradient maintains that Silicon Graphics bought the rights to use NetLS when the system still belonged to Hewlett-Packard Co and neglected to adopt Gradient’s subsequent upgraded and enhanced models, iFORLS and then EZ-LoK. Meantime Gradient is on the verge of issuing another enhanced version of EZ-LoK, for Windows NT. EZ-LoK presently runs under Solaris, AIX and HP-UX. The firm will release further information on its Distributed Computing Environment implementation for Unix System V.4 MP RAS 3.0 this week.
