The CRAY-1 computer (Serial No. 1) was installed at the Los Alamos Scientific Laboratory (LASL) on April 1, 1976. This report describes experience with the CRAY-1 since that time. The first six months of the period were spent in a detailed evaluation of the hardware. The machine successfully passed the performance thresholds that had been established, and on October 1, 1976, it became available for productive use. Initial efforts were concentrated on achieving an early production capability for several large codes. In order to achieve this objective, a link was established between the CRAY-1 and CDC 7600 running the Livermore Time-Sharing System (LTSS). This link became operational in December 1976, and security approval was received in January 1977. The first major production code became operational in May 1977, and production usage has increased since that time. An operating system for the CRAY-1 that is tailored to the LASL computing environment is currently being developed. Several smaller-scale computers with extensive software facilities that will support the CRAY-1 are being obtained. 4 figures.
