Technical details of the SN-MIPS system:
The NSC user surveys have indicated an increasing demand for large primary memory areas. We are therefore happy to be able to announce that the SN-MIPS system will have 96 GByte of shared memory and fast large scale secondary storage of at least 6 TByte. Compared to the shared memory of the Cray C90 at NSC this is an increase by a factor of 48 in size. The new system is thus especially suitable for applications that make use of large primary memory and fast large scale secondary storage. For example applications that diagonalize large matrices in core or applications that use out of core solvers to handle even larger problems.
From July 1st until the installation of the SN-MIPS system a smaller SGI Origin 2000 interim system will be available. The user environment will be the same on the Origin 2000 system as on the SN-MIPS system. Users will only experience the positive change of increased performance due to more and faster processors, larger total shared memory and larger secondary storage when they are transfered from the interim system to the SN-MIPS system. The interim system will be equipped with 32 processors, a total of 32 GByte shared memory and 16 GFLOP/s total peak performance. Already the interim system thus has 16 times as large shared primary memory as the Cray C90.
The new SN-MIPS system will replace the NSC Cray C90, which will be phased out during the summer following the installation of the interim system. Users with allocations on the C90 will be offered time on the new system. At NSC we will do our best to assist C90 users so that their migration to the new SN-MIPS system will be as quick and easy as possible. New specialized courses on the new system and on how to migration to it is under development and will be given at several occasions during the year. Furthermore, a new user guide that describes all systems at NSC will be made available and distributed to our users. Check out our web-page http://www.nsc.liu.se/ for information about courses and the new user guide.
It is possible to apply for time on the new SN-MIPS system already in the current application round announced by the Swedish National Allocations Committee for High Performance Computing (SNAC) with deadline May 8, 2000. We welcome proposals applying for time on the new system as well as on our Cray T3E and especially encourage people with applications that require large primary memory and fast and large secondary storage to submit proposals applying for time on the new SN-MIPS system available late 2000.
