Job abstractJV_description

A PhD Research Fellowship in Informatics is available at the Department of Informatics.

The fellowship period is 3 years. Candidates may be offered one additional year by the Department of Informatics; the 4 years position then entails a compulsory work load of 25% that consists of teaching and supervision duties.

No one can be appointed for more than one PhD Research Fellowship period at the University of Oslo.Starting date no later than 01.10.2019.

More about the position

Through recent years, we have seen an increase in the number of languages that run on top of runtime systems. JavaScript, Java, C#, Scala, Python, and Go are just a few examples of widely adopted managed languages that run on top of such runtimes. The extensive use of managed languages reveals that application developers want to take advantage of all the benefits of using a runtime system, and also shows that current runtimes' design is mature, providing competitive performance when compared to traditional languages such as C and C++. Therefore, we foresee that runtime system utilization will continue to grow in the future, suggesting the need for more research in this area. In addition, many research works have shown that memory management algorithms, Garbage Collection (GC) algorithms in particular, can be tuned in order to prioritize specific performance metrics such as latency, throughput, and memory utilization (footprint). With the recent development of new GC algorithms providing ultra-low latency (e.g., NG2C, C4, Shanendoah, ZGC), the memory management landscape becomes more complex. In particular, selecting the correct GC for a specific application is not trivial since each GC provides different trade-offs.

Thus, this PhD proposal addresses the need to study how current GCs perform regarding the above mentioned metrics (in particular, latency and throughput) to better understand their trade-offs and select the right GC solution.

An example of such trade-off is the need of higher footprint and lower throughput in order to guarantee lower pause times, i.e. lower latency (as is the case with C4, Shanendoah, and ZGC).

Findings on how current GCs behave, for example, with smaller footprints, could affect both migration and other related memory management works (e.g., in dynamic vertical scalability algorithms) which try to reduce the amount of memory used before a JVM live migration or during periods in which applications have low activity. In short,  not only current GCs must be studied, but trade-offs must also be ameliorated; for example, this PhD will explore a possible solution which is to use the underlying host operating system to identify unmodified memory pages that could be skipped during a full tracing cycle, thus helping to minimize applications pause times.

The candidate will be supervised by a group of supervisors in the Programming and Software Engineering Group who have broad competence in informatics:

Paulo Ferreira, Professor, Department of Informatics, UiO

Eric Jul, Professor, Department of Informatics, UiO
