An experiment with Gnocchi – (the database) – Part 3

In Part 2, I summarized the iterations applied to the kernel (the piece of CUDA code that executes on GPU) to remove the bottlenecks encountered during profiling, like using shared memory to avoid non-coalesced memory access. In this part, I will talk about the final version of the kernel and using the GPU in other […]

An Experiment with Gnocchi – (the Database) – Part 1

Background (Why): Openstack has component: Ceilometer (Telemetry). Ceilometer was huge and its main purpose was to help with the Monitoring and Metering of whole of th OpenStack. But because of the scale at which OpenStack operates, Ceilometer would often fall behind and become a major bottleneck for the same function it was designed to do. […]

SUSE Linux Enterprise 12 and IBM POWER8

Once again SUSE and IBM are jointly developing the next generation of Linux for IBM hardware because, as the SUSE motto says, “We adapt, you succeed.” In 1999, SUSE worked with IBM to bring System z into a new era, bringing Linux to the mainframe. Now, we are applying our deep software engineering experience to […]
