Lindon, Utah-based SCO said it had terminated the Sequent contract for improper transfer of the company’s Unix source code and development methods into Linux, one of the central arguments of its $3bn breach of contract and unfair competition claim against IBM.
SCO said that IBM/Sequent had contributed 148 lines of code relating to NUMA (non-uniform memory architecture) and RCU (remove copy update) from Dynix into the Linux 2.4 and 2.5 kernels, totaling 168,276 lines of code.
SCO also claimed that IBM/Sequent contributed Unix-based development methods to Linux in addition to the lines of code, and failed to treat Dynix as a part of the original System V software, which according to SCO it was required to do as part of its contract.
IBM had not responded to SCO’s termination at press time, although the company previously maintained that it has an irrevocable and perpetual Unix license after SCO terminated the license for its AIX version of Unix in June.
SCO said it had given IBM two months written notice prior to the termination of the Sequent Unix license and maintained that the termination is self-effectuating and does not require court approval.
