Cray Research SV1ex-1

This Cray Research SV1ex-1 vector supercomputing system was recently donated by the Ford Motor Company, which had five SV1 systems for safety and structural analysis. This SV1e model was introduced in 1999, runs the UNICOS operating system, and is in the same family as the J90 systems. You could use the SV1 processor modules to upgrade a J916/J932 system.

This system includes 8 processor boards with 4 processors per board for a total of 32 processors. The processors are connected to the outside world with counter-rotating GigaRing that can move data at 800 MBytes/Sec. This system is a little unusual because all 8 processor modules have GigaRing interfaces. It is an indication that this system had very high I/O requirements. It has 8 memory boards totaling 64 GB or RAM.

Jonathan White prepairs the SV1 processor cabinet to come off the delivery truck.

The front of the Cray SV1. The cabinet in the middle holds the CPUs and memory.

The smaller cabinets to the left and right hold the I/O subsystems.

The left PCB in this CPU module is the Gigaring interface.

The right PCB holds the quad processors.

This is one of 8 8GB memory boards on the Cray. When this machine was introduced that was an enormous amount of memory.

With the doors open you can see the CPUs and memory in the middle cabinet.

The front and rear of the Cray Multipurpose Node (MPN-1).

The chassis contains a HyperSPARC processor running the VxWorks real-time operating system.

The MPN contains two SBuses so it can support up to 8 SBus I/O cards.

The only SBus card currently installed is for 100 Mb Ethernet.

It can support Ethernet, FDDI, ATM, SCSI disks, and Supervisory Channel SBus (SC01).

The right I/O Cabinet.

The Multipurpose Node (MPN) is at the top of the right cabinet. The MPN is a SPARC based controller that connects the GigaRing to Sbus interface boards. This one has a 100BASE-T Sbus board installed and an empty Sbus slot. The empty Sbus slot probably contained the required SCSI interface board.
