![]() The main compute node is a n2-highmem-128 machine running Debian Linux 11, with 128 vCPUs and 864 GB of memory, and 100 Gbps egress bandwidth support. We designed a cluster of one computational node and 32 storage nodes, for a total of 64 iSCSI block storage targets. The maximum persistent disk capacity that you can attach to a single virtual machine is 257 TB, which is often enough for traditional single node applications, but not in this case. Here’s how we configured our Compute Engine environment for the challenge.įor storage, we estimated the size of the temporary storage required for the calculation to be around 554 TB. Architecture overviewĬalculating π is compute-, storage-, and network-intensive. You can see that we're adding digits of π exponentially, thanks to computers getting exponentially faster. History of π computation from ancient times through today. Total I/O: 43.5 PB read, 38.5 PB written, 82 PB total.Total storage size: 663 TB available, 515 TB used. ![]() Total elapsed time: 157 days, 23 hours, 31 minutes and 7.651 seconds.Compute node: n2-highmem-128 with 128 vCPUs and 864 GB RAM. ![]()
