GpuScan and SSD-To-GPU Direct DMA
An article for none-Japanese readers....What I'm recently working on is a feature to load data blocks from NVMe-SSD to GPU using peer-to-peer DMA. It allows to bypass the CPU/RAM under a series of data loading process, thus, also allows to reduce number of expensive data copy. Once data blocks are l…

A tale of an impossible bug: big.LITTLE and caching
When someone says multi-core, we unconsciously think SMP. That worked out well for us until recently when ARM announced big.LITTLE. ARM’s big.LITTLE architecture is the first mass produced AMP architecture and as we’ll see next, it raises the bar for how hard multi-core programing is.

Robin Hood Hashing should be the default hash table implementation (2013)
There’s a neat variation on open-addressing based hash tables called Robin Hood hashing . This technique isn’t very well-known, but it makes a huge practical difference because it both improves performance and space utilization compared to other “standard” hash tables (e.g. chaining ). It also eliminates the major…

How to allocate memory
Many programmers use malloc() and free() and pay no more mind to "allocating memory", but I often find 2-20× speed improvements by rethinking memory usage, so it is something I usually want to examine when joining a distressed project.
