High performance transaction systems on the SB-PRAM

The SB-PRAM is a shared memory parallel machine under construction in Saarbrucken. With the help of simulations we have evaluated the performance of transaction systems on this machine. We use the well known, DEBIT/CREDIT benchmark as workload. According to the simulations the machine reaches 6000 transactions per second with, 256 data disks, 32 log disks and 128 processors, although each processor has only 8 MIPS. With a partial run time analysis we support this surprisingly high transaction rate. >
