In 2004 I was working for Microsoft in the Xbox group, and a new console was being created. With fixed hardware it’s easy to construct a linked list that will stay in L1, or will always require a trip to L2, or will always require a trip to main memory.

Breaking that assumption allowed Ceph to introduce a new storage backend called BlueStore with much better performance and predictability, and the ability to support the changing storage hardware landscape. The storage backend is the software module directly managing the storage device attached to physical machines.

To explain this example in more detail: The profiler periodically interrupts software execution, and for those disconnected stacks it happens to be the execution of the kernel software ("vfs*", "ext*", etc.). These partial stacks get grouped together on the left. Click here for a longer explanation. Just to name a couple of languages.

The behavior of the Windows scheduler changed significantly in Windows 10 2004, in a way that will break a few applications, and there appears to have been no announcement, and the documentation has not been updated. First, a bit of operating-system design context. The answer is hardware interrupts. The new undocumented reality.

After working with DynamoDB for only three days, they had already managed to go from the design phase to a fully production-ready deployment that could handle the biggest advertising event of the year. DynamoDB runs on a fleet of SSD-backed storage servers that are specifically designed to support DynamoDB. As Amazonâ??s

With the motion extension, it was accepted as the video coding standard for digital cinema in 2004. There is a potential benefit in reusing the hardware in place for video compression/decompression. The goal of this library is to ease the integration in software from the image community.
