Motivation
Probably, in a near future, even personal computer in a domestic
domain will be based on a parallel architecture with more than ten
logic processors. Nowadays, dual-core and multi-threading processors are
widespread used, and soon, we will see processors in which a great deal
of threads can be executed in parallel.
However, the majority of the programs and current applications
(numeric or symbolic) are not designed to exploit all the possibilities
of these multicore/multithread processors. To manually parallelize the
existent or future software applications is a tough, non-productive
and inefficient job. So, in practice, new parallel languages, libraries, tools and
compilers will be necessary in order to generate
applications able to take advantage of the potentiality of parallel
architectures.
Antecedents
Our research group has been researching for more than a decade on
techniques and technologies related to automatic parallelization and
optimization of codes. We have visited and collaborated with pioneer
research groups, like Polaris (led by Prof. David Padua) or Apart (led by Prof. Michael
Gerndt). From this work, several contributions arised in the field
of automatic parallelization/optimization of Fortran codes, easier to
tackle due to the lack of pointers and dynamic data structures.
More recently, and based on the accumulated
experience, we have extended the sphere of activity of our techniques
to let them face codes written with more evolved languages: C, C++ or
Java. All these languages have in common the possibility of using
complex data structures based on pointers and dynamic memory
allocation. However, there is still a lack of compiler techniques to
deal with the automatic optimization of such codes. The main
limitation of these compilers is that they are not able to
automatically extract from the source code the necessary information
to exploit parallelism, locality, etc. To solve this, we basically
need a description of the memory locations read and written at each
code statement. More precisely, the topology and properties of the
data structures used in the code must be automatically captured via
static analysis.
During the last years,
we have developed a shape analyzer
which precisely capture the properties and topology of the data
structures used in pointer-based codes. This previous work was carried
out by F. Corbera for his Ph.D. [1-6,8,9]. Later on, we have used this
first implementation of the shape analyzer to develop a dependence
test able to successfully detect parallel loops [3,15,16,23]. We have
also explored the applicability of the shape analysis in oder to
exploit locality and parallelism in pointer-based codes [7,
10-12,14,17]. Using Java, NetBeans, CVS, several GUI libraries, and
extending the Cetus
compiler infrastructure, we have reformulated the shape analysis using
"Coexistent Links Sets" [18-19], reducing the amount of memory
required during the analysis and increasing the precision in the
description of the data structures captured in dynamic codes. We have
validated this new shape analysis approach with several codes in which the used data structures are
successfully identified. Besides, we are researching strategies aimed
at reducing the complexity of such analysis [20,34]. For his
Ph.D. [35], Adrian Tineo has added interprocedural support to deal
with recursive codes [25,32,33] and a data dependence test that
successfully detect loop-carried dependences in loops and recursive
functions that traverse recursive data structures.
Current Work and Main Goals
Current steps are directed towards four main projects:
- New parallel languages: Chapel. In collaboration with Brad
Chamberlain, from Cray Inc., we want to contribute to the Chapel project, mainly
related with data redistribution, the sparse and irregular data
structures distribution problem, parallel Input/Output, and with work
stealing and task parallelism.
- Load balance for heterogeneous architectures. In
collaboration with María Jesús Garzarán, from UIUC, and with Jose Nunez-Yanez
from Univ. of Bristol, we are also
dealing with the problem of automatically balance the workload on
heterogeneous architectures, composed of multicores, GPGPUs and FPGAs.
