lucene: Lucene searching server and client, which are based on Lucene regression framework https://github.com/mikemccand/luceneutil
nanonap: Linux kernel patch and the nanonap kernel module.
microbench: Instrumentation code for C micro-benchmarks used in the paper.
dacapobench: JikesRVM patch for running Dacapo benchmarks as the batch workload.
misc: scripts for processing the results.

elfen's Issues

Code of elfen scheduling is missing

Hello, i read your elfen scheduling paper, here are some problems i met:

    1. There are 4 scheduling methods which you've introduced, but i can't find the code on this project or on anywhere of your github.
    1. You said that "We implement ELFEN in the Linux kernel and in compile-time instrumentation that self-schedules batch workloads, using both C and Java applications, demonstrating generality." But i don't know how you do this.

Thanks very much if you could add the missing code!

hello, about ipc=0.01 and ipc=1 batch workloads, there seems to be no code on github

hello yangxi, i am reproducing your work about elfen, but i can't find the code of producing the batch workloads of ipc=0.01 and ipc=1, you said in the paper that

The first uses a non-temporal store and memory fence to continuously block on memory, giving an IPC of 0.01. For instance, the Intel PAUSE instruction has a similar IPC. The other performs a tight loop doing nothing (IPC=1) when running alone.

But i am wondering how you realize it, thanks for you reply!!!
