News from ScaliMunich 30 October 2000 Hakon Bugge from Scali gave an outlook on the actual situation and coming products as a scheduled ScaSAN architecture, MPI2 and MPICH.
Scali was founded in 1997 and has 1000 installed nodes in 15 countries with middleware and management software for scalable computing. On October 6, Scali 2.1 was delivered with Cray Shmem ready for beta testing. An internal profiling is now possible to deliver performance statistics. A transferrate of more than 300 MByte/s between two processors are possible.
Instead of transferring user data from an remote node via different system buffers - this means the data is transferred six times - it is much easier in a shared address space. There the data can be transferred directly from the remote user memory into the user memory of the requesting node.
He discussed the ScaSAN architecture, this means a System Area Network (SAN) on top of SCI (Scalable Coherent Interface). Further he gave some estimated timings concerning MPI2, Shmem will be probably available in 4th quarter 2000, the one-sided communication in the 1st quarter of 2001, MPICH 2000 in the second half of 2001 and the full MPI2 functionality is available in the 4th quarter 2001.
