Fujitsu VP2000 series Supercomputer is a pipeline supercomputer series developed by Fujitsu. The peak performance of this series ranges from 375 MFLOPS of the VP2100/10S to 5 GFLOPS of the VP2600/10. Operations are mainly performed by using a pipeline which is called “Universal Pipeline”. This pipeline provides a capability of one of the following operations such as a multiplication, an addition, a multiplication-addition or a logic operation at one time. In addition, in case that two pipelines are used, they can perform such operations concurrently. The VP2200, the VP2400 and the VP2600 have two pipelines and both pipelines are used for multiplication-addition concurrently to attain the peak performance. FORTRAN77 EX/VP, which is developed to utilize this hardware, makes it possible to schedule these two pipelines effectively. Using the VP2600/10, the performances of LINPACK problem for a matrix of order 100 and for a matrix of order 1000 are 249 MFLOPS and 4009 MFLOPS respectively.
