kandi X-RAY | xstore Summary

xstore is a C++ library. xstore has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

XStore is an RDMA-enabled ordered key-value store targeted at a client-sever setting. Specifically, the server has an in-memory B+Tree; and the client uses one-sided RDMA READs to traverse the B+Tree. To accelerate the lookup, we deploy a learned cache (xcache) at the client to accomplish the traversal in one round-trip (if the learned cache is all cached). Even if the xcahe is not cached, XStore client only needs at most 2 round-trips for the traversal.

Inserting parameters into a template loop

Asked 2021-Sep-13 at 09:03

Is it possible to use the parameters declared in the parameters' node (see the XDT file) inside a foreach loop in the template? I'd have to add a namespace? If yes which one?

When you reference a field, it's looking inside the element you are currently in. So you will need to tell BI Publisher where it is if it's not in the current element. Just add ../ for each level you need to go up the tree, and then once you get into the first common element, you can then go back down.

So if you are in a You can get the parameter attribute value, where the attribute name = GroupName, by doing:

Let's try and break down the problem into two discrete steps:

Group discrepancies based on Date, Store and Register
Output an object describing the Date, Store, Register and all sources associated with that group

For the first step, we can make use of Group-Object:

QUESTION

Machine coding an Arduino/Atmel328 over a serial line from a tethered (host) PC

Asked 2020-Jun-18 at 23:42

I'm trying to write a program for the AVR Atmel 328 chip that will allow me to send machine code instructions to the chip over a serial line, run/execute them on the chip, and interrogate the results by reading chip memory and sending the contents back over the serial line. This is the genesis of the idea: 3-instruction Forth by Frank Sergeant.

The remote-store and remote-fetch instructions appear to be working fine, but I've not been able to get the remote-call instruction (XCALL() function) to work. The approach I've taken is to coerce a 16-bit address into a subroutine by casting it as a function pointer.

Below is the code that is running on the Arduino Nano (compiled in the Arduino IDE and uploaded using the USB cable via the bootloader)

Any insight would be greatly appreciated! (I can add diassembled code, my remote instructions etc, if that helps).

Thanks in advance!

You didn't tell us the exact name of your chip but I suspect you are using the ATmega328P.

The ATmega328P cannot execute instructions from RAM. You will need to figure out how to write the code to flash before you can execute it. You might want to use a bootloader like Optiboot to write the program to flash, or you could study Optiboot to see how it works. Note that the flash is only rated for a limited number of erase/write cycles (typically 10000).

Also, your C++ syntax is wrong. To call a function, you always need to use parentheses. So you would write fGf(). instead of just fGf.

Install xstore

XStore is a header-only library. Basically, git clone https://github.com/SJTU-IPADS/xstore.git xstore-open --recursive is all you need to use XStore. To use XStore, just include the required header to your project. For instance, xkv_core/src/xtree/mod.hh provides the implementation of XTree.
Build

Support

This codebase has the basic functionality of XStore, including basic XCache training, deployment, various learned models. It also provides various benchmark code for XCache analysis and static benchmark code. Other features will be released soon.
