Descripción
COMPSs is a programming model which is able to exploit the inherent concurrency of sequential applications and execute them in a transparent manner to the application developer in distributed computing platform. This is achieved by annotating part of the codes as tasks, and building at execution a task-dependence graph based on the actual data used consumed/produced by the tasks. The COMPSs runtime is able to schedule the tasks in the computing nodes and take into account facts like data locality and the different nature of the computing nodes in case of heterogeneous platforms. Additionally, recently COMPSs has been enhanced with the possibility of coordinating Web Services as part of the applications. COMPSs supports Java, C/C++ and Python as programming languages.
Consider the following scenario: we have a large database of gene sequences,
hundreds of thousands, even, millions (e.g. in GenBank). In order to enable
fast similarity search, clustering, phylogenetic reconstruction, etc. it is
usual to consider
the set of distinct k-mers of each sequence in the database (typical values of
k are around 20), but instead of using the full set of k-mers of each
sequence, we will use a sketch (a random sample) instead: computing the
similarity (Jaccard, cosine, ...) of the sketches yields accurate estimates of
the true similarities.
One problem that we face then is that of producing random samples for each
gene sequence in an efficient way. Practical constraints require, among other
things, that the algorithms can be parallelized and that the size n of the set
from which
we draw the samples is not known in advance.
Algorithms such as MinHash (mash) or bottom-k are easy, efficient and will
produce random samples of a given fixed size. Because the size of the sketches
is fixed in advance these schemes have limited accuracy and adapt poorly when
the database contains very different types of gene sequences (small/medium/
large sequences, low/high variability, ...). Recent proposals, such as
FracMinHash (sourmash) are also fast, simple and efficient, but produce random
samples of linear size w.r.t. the size n of "population". For FracMInHash,
similarity estimates are very accurate, but this is at the expense of bigger
sketches and, hence, larger processing times too.
In the talk I will describe my recent work on two sublinear random sampling
algorithms. The first is Affirmative Sampling (Lumbroso and M., 2022) which is
the first of its kind, as far as we know. Affirmative Samping is simple and
efficient, and its standard variant produces samples of (expected) size k
ln(n/k) + O(k), for a fixed parameter k. Another variant generates samples of
expected size Theta(n^alpha), for a given valua alpha, 0 < alpha < 1.
Unfortunately, parallelization of Affirmative Sampling will render different
samples depending on how the database is "split" among parallel threads, which
is not desirable in practice.
In a more recent work, we introduce MaxGeomHash (Hera, Koslicki and M.,
submitted) which admits "deterministic" parallelization, and has better
concentration around the expected size of the samples. The algorithm is also
very simple, and effcient in practice. The standard variant (MGH) produces
samples of expected size k log_2(n/k) + k + O(1), and variance is 1.215 ... k
+ o(1); for the variant alpha-MGH, 0 < alpha < 1, we have samples of expected
size is f(alpha) n^alpha + o(n^alpha), for a explicitly computable f(alpha),
and the variance is n^alpha + o(n^alpha). MGH achieves accuracy close to that
of FracMInHash, while only needing a fraction of the computational resources
needed by FracMInHash.
We will end briefly describing some of the applications and implications of
these algorithms, besides the initial example motivated in computational
biology.

Descripción
RISC-V is an open instruction set standard which is experiencing extraordinary growth all over the world in numerous areas of focus ranging from HPC & ML to the data center to embedded computing. The standardization activities are community driven by expert members (from industry, academia and individuals). BSC is one of the community members that is contributing to the ecosystem. This course is an opportunity to get familiar with technical aspects of the standard through a combination of lectures and hands-on sessions.
This course identifies topics that are both fundamental to computer architecture and relevant to the design of RISC-V based solutions of the future. The emphasis is always on insights that will be useful to the (under)graduate student, whether he/she goes on for a PhD or joins a software or hardware development team. We will deal with principles, trade-offs, and implementation details related to the RISC-V standard. Along the course, the students will get familiar with some layers of the RISC-V software and hardware stacks using a learning-by-doing methodology. This will provide a mechanism to the students to understand the RISC-V ecosystem, BSC know-how and activities related to RISC-V, and explore the potential of the ISA to freely develop new technologies..
Topics will cover aspects like: how to boot an operating system, how to deploy a container and execute an application, how to tune an algorithm for improving its performance through the addition of custom instructions, and finally, how to improve the performance of an HPC application by taking advantage of the RISC-V Vector extension.

Descripción
The objectives of this course are to understand the fundamental concepts supporting message-passing and shared memory programming models. The course covers the two widely used programming models: MPI for the distributed-memory environments, and OpenMP for the shared-memory architectures. The course also presents the main tools developed at BSC to get information and analyze the execution of parallel applications, Paraver and Extrae.
It also presents the Parallware Assistant tool, which is able to automatically parallelize a large number of program structures, and provide hints to the programmer with respect to how to change the code to improve parallelization. It deals with debugging alternatives, including the use of GDB and Totalview. The use of OpenMP in conjunction with MPI to better exploit the shared-memory capabilities of current compute nodes in clustered architectures is also considered. Paraver will be used along the course as the tool to understand the behavior and performance of parallelized codes. The course is taught using formal lectures and practical/programming sessions to reinforce the key concepts and set up the compilation/execution environment.
