Interestingly though, what happens with such a benchmark is that the performance that is being reported differs quite dramatically from LINPACK performance results. LINPACK, which began its evolution in the late 1970s, does measure how well the CPU is able to do floating point arithmetic, but it doesn’t really capture what’s happening with the rest of the machine-especially in those more pressured parts involved with data movement, most notably the interconnect network.

It has already been distributed in its early form to the vendor community to test and comment upon, leading to a number of valuable insights about more alterations and again, will be put to the test of a wider set of systems once the code is opened to more users beginning after SC13.īut the community needs to start somewhere, especially when it comes to kickstarting the process of moving from a benchmark that emphasizes the floating point capabilities that were a key factor in systems from 20 years ago. He says that HPCG will undergo many tweaks over the next couple of years before it’s ready for primetime. This new benchmark will be announced in further detail tomorrow (Tuesday) during the Top500 announcement and will be made available to be tested across a wider array of systems.ĭongarra says that while there are a few systems that have reported early numbers using the “alpha” version of this benchmark, it’s not time to think about replacing LINPACK just yet. The news about this effort drew a great deal of positive reaction from the scientific computing community in particular as it is more in tune with the types of modern and future simulations that are actually running on LINPACK top-ranked systems on the Top500.
Jack Dongarra.Īt that time, he described a new benchmarking effort that is taking shape with the input of several collaborators, called the high performance conjugate gradient (HPCG) benchmark. Since 1987 - Covering the Fastest Computers in the World and the People Who Run Themīack in June during the International Supercomputing Conference (ISC), we discussed the need for a potential alternative to the current LINPACK benchmark, which is the sturdy yardstick by which supercomputing might is measured, with its creator, Dr.
