A look back at 2014 and plan for 2015
2014 was a year of changes. I completed my doctoral thesis, not without difficulty in its redaction (I am not a very good writer), and I also relocated with my girlfriend to Illinois. And I started to work at Argonne. I think I got lucky -- I ended up getti...

Profiling the Thorium actor model engine with LTTng UST
I have been working with perf for a while now, butfound it only useful mostly for hardware counters. I typically use this command to record events ($thread is the Linux LWP (lightweight process) thread number): perf record -g \     -e cache-references,cache...

The public datasets from the DOE/JGI Great Prairie Soil Metagenome Grand Challenge
I am working on a couple of very large public metagenomics datasets from the Department of Energy (DOE) Joint Genome Institute (JGI). These datasets were produced in the context of the Grand Challenge program. Professor Janet Jansson was the Principal Inves...

The Thorium actor engine is operational now, we can start to work on actor applications for metagenomics
I have been very busy during the last months. In particular, I completed my doctorate on April 10th, 2014 and we moved from Canada to the United States on APril 15th, 2014. I started a new occupation on April 21st, 2014 at Argonne National Laboratory (a U.S...

Symmetric initial actor placement with biosal thorium actor model implementation:

node/0 worker/0 Frequency list
node/0 worker/0 Frequency dna_kmer_counter_kernel => 18
node/0 worker/0 Frequency argonnite => 1
node/0 worker/0 Frequency sequence_store => 1
node/0 worker/0 Frequency aggregator => 18
node/0 worker/0 Frequency kmer_store => 1

node/0 worker/16 Frequency list
node/0 worker/16 Frequency dna_kmer_counter_kernel => 18
node/0 worker/16 Frequency sequence_store => 1
node/0 worker/16 Frequency aggregator => 18
node/0 worker/16 Frequency kmer_store => 1

node/0 worker/21 Frequency list
node/0 worker/21 Frequency dna_kmer_counter_kernel => 18
node/0 worker/21 Frequency sequence_store => 1
node/0 worker/21 Frequency aggregator => 18
node/0 worker/21 Frequency kmer_store => 1

The actor model of computation
This video has Professor Carl Hewitt in it. Hewitt is the original creator of the concept of actors. Hewitt created the concept of actors in 1973 with Bishop, and Steiger. Everything is in this paper and it's 11 page. If you have little time, you can read o...

I wrote a previous post on Class-Like Structures for usage in C, in order to create objects that would allow for both inheritance and polymorphism. However, it's annoying to keep a pointer to each type of required function fo...

Profiling an high-performance actor application for metagenomics
I am currently in an improvement phase where I break, build and improve various components of the system. The usual way of doing things is to have a static view of one node among all the nodes
inside an actor computation. The graphs look like this: 512x16 1...

Is it required to use different priority in a high-performance actor system ?
I was reading a log file from an actor computation. In particular, I was looking at the outcome of a kmer counting computation performed with Argonnite, which runs on top of Thorium. Argonnite is an application in the BIOSAL project and Thorium is the engin...

Early prototype of our work with actors for genomics
Our work on biosal (bsal) is advancing well. Here is an example of what you can do easily with the actor model. This actor machine emulator contains 4 biosal nodes, each with 24 threads and 23 workers (23 worker threads and 1 communication thread). The acto...
