What you will need for creating a bootable microSD card ?
1. A development machine with some version of linux (I had Ubuntu installed on my machine) .
You should have root access on this machine (or at least the ability to mount/unmount devices and run
fdisk).
2. A microSD card adapter. Your hardware should contain an adapter that converts microSD card into
an SD card which you can use on your computer. If your computer/laptop does not have an SD card
reader, please contact the course staff to get a USB adapter for the microSD card.
The example covered in this document will show the steps for setting up a brand new 2GB microSD card.
First insert your card into your development machine’s flash card slot.
On my Ubuntu 12.04 machine, the newly inserted card shows up as /dev/mmcblk0(or /dev/sdb) (with any
partitions showing up as /dev/mmcblk0p1 (or /dev/sdb1), /dev/mmcblk0p2(or /dev/sdb2), etc.) and that is
the device name that will be used through this example. You should substitute the proper device name for
your machine. You can use ’mount’ or ’df’ to see where the card mounts on your machine.

What you will need for creating a bootable microSD card ?
1. A development machine with some version of linux (I had Ubuntu installed on my machine) .
You should have root access on this machine (or at least the ability to mount/unmount devices and run
fdisk).
2. A microSD card adapter. Your hardware should contain an adapter that converts microSD card into
an SD card which you can use on your computer. If your computer/laptop does not have an SD card
reader, please contact the course staff to get a USB adapter for the microSD card.
The example covered in this document will show the steps for setting up a brand new 2GB microSD card.
First insert your card into your development machine’s flash card slot.
On my Ubuntu 12.04 machine, the newly inserted card shows up as /dev/mmcblk0(or /dev/sdb) (with any
partitions showing up as /dev/mmcblk0p1 (or /dev/sdb1), /dev/mmcblk0p2(or /dev/sdb2), etc.) and that is
the device name that will be used through this example. You should substitute the proper device name for
your machine. You can use ’mount’ or ’df’ to see where the card mounts on your machine.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
