Samsung DRAMs in Massive Leibniz SuperMUC

The Leibniz Supercomputing Centre's SuperMUC supercomputerToday Samsung announced that its chips are used exclusively to make up the 324-terabytes of DRAM in Germany’s new Leibniz Supercomputing Centre SuperMUC supercomputer.

Samsung’s release tells us that the SuperMUC, the most powerful supercomputer system in Europe, is an IBM System x iDataPlex dx360 M4 server built using over 18,000 Intel Xeon CPUs and over 80,000 4GB DRAM modules from Samsung.  (Simple math makes this out to be 82,944 modules.)

That looks like a lot of silicon!  Let’s see how much that might be.

A 4GB parity DRAM module would use nine 4Gb DRAM chips, which Samsung appears to Continue reading

A Change to Computing Architecture?

Venray's TOMI Die LayoutI got a phone call yesterday from Russell Fish of Venray Technology. He wanted to talk about how and why computer architecture is destined for a change.

I will disclose right up front that he and I were college classmates.  Even so, I will do my best to give the unbiased viewpoint that my clients expect of me.

Russell is tormented by an affliction that troubles many of us in technology: We see the direction that technology is headed, then we consider what makes sense, and we can’t tolerate any conflicts between the two.

In Russell’s case, the problem is the memory/processor speed bottleneck.
