A Comparative Survey of the HPC and Big Data Paradigms: Analysis and Experiments

Autor: Dounia Khaldi, Barbara Chapman, Hamidreza Asaadi

Publikováno v: CLUSTER

Many scientific data analytic applications need huge amounts of input, which can often consist of more than several TBs of data. This emphasizes the high I/O and processing/computational cost requirements of these algorithms. Tasks in these programs

Optimizing GPU Register Usage: Extensions to OpenACC and Compiler Optimizations

Autor: Rengan Xu, Barbara Chapman, Xiaonan Tian, Deepak Eachempati, Dounia Khaldi

Publikováno v: ICPP

Using compiler directives to program accelerator-based systems through APIs such as OpenACC or OpenMP has increasingly gained popularity due to the portability and productivity advantages it offers. However, when comparing the performance typically a

OpenSHMEM

Recent reports on challenges of programming models at extreme scale suggest a shift from traditional block synchronous execution models to those that support more asynchronous behavior. The OpenSHMEM programming model enables HPC programmers to explo

LLVM '15 Proceedings of the Second Workshop on the LLVM Compiler Infrastructure in HPC, Nov 2015, Austin, United States. pp.2:1--2:8, ⟨10.1145/2833157.2833158⟩
LLVM@SC

We extend the LLVM intermediate representation (IR) to make it a parallel IR (LLVM PIR), which is a necessary step for introducing simple and generic parallel code optimization into LLVM. LLVM is a modular compiler that can be efficiently and easily

OpenSHMEM as a Portable Communication Layer for PGAS Models: A Case Study with Coarray Fortran

Autor: Dounia Khaldi, Deepak Eachempati, Barbara Chapman, Naveen Namashivayam

Publikováno v: CLUSTER

Languages and libraries based on the Partitioned Global Address Space (PGAS) programming model have emerged in recent years with a focus on addressing the programming challenges for scalable parallel systems. Among these, Coarray Fortran (CAF) is uni

An Evaluation of Anticipated Extensions for Fortran Coarrays

Autor: Dounia Khaldi, Barbara Chapman, Shiyao Ge, Deepak Eachempati

Publikováno v: 2015 9th International Conference on Partitioned Global Address Space Programming Models.

A set of parallel features, broadly referred to as Fortran coarrays, was added to the Fortran 2008 standard. It is expected that several new parallel features, designed to complement or augment this feature set, will be added to the next revision of

Publikováno v: Lecture Notes in Computer Science ISBN: 9783319264271
OpenSHMEM

OpenSHMEM is a library interface specification which has resulted from a unification effort among various vendors and users of SHMEM libraries. OpenSHMEM includes routines which aim to support a PGAS programming model, encompassing data management, o
