LogCA: A High-Level Performance Model for Hardware Accelerators Muhammad Shoaib Bin Altaf ∗ David A. Wood AMD Research Computer Sciences Department Advanced Micro Devices, Inc.

Unfortunately, accel- 0.1 erators don’t always live up to their expectations and may under- perform in some situations. Understanding the factors which effect Time (ms) 0.01 Break-even point the performance of an accelerator is crucial for both architects and 0.001 programmers early in the design stage. Detailed models can be 16 64 highly accurate, but often require low-level details which are not 256 1K 4K 16K 64K available until late in the design cycle. In contrast, simple analytical Offloaded Data (Bytes) models can provide useful insights by abstracting away low-level system details. (a) Execution time on UltraSPARC T2. In this paper, we propose LogCA—a high-level performance 100 model for hardware accelerators. LogCA helps both programmers SPARC T4 UltraSPARC T2 GPU and architects identify performance bounds and design bottlenecks 10 early in the design cycle, and provide insight into which optimiza- tions may alleviate these bottlenecks. We validate our model across Speedup 1 Break-even point a variety of kernels, ranging from sub-linear to super-linear com- plexities on both on-chip and off-chip accelerators. We also describe the utility of LogCA using two retrospective case studies. -

Foreign Library Interface by Daniel Adler Dia Applications That Can Run on a Multitude of Plat- Forms
30 CONTRIBUTED RESEARCH ARTICLES Foreign Library Interface by Daniel Adler dia applications that can run on a multitude of plat- forms. Abstract We present an improved Foreign Function Interface (FFI) for R to call arbitary na- tive functions without the need for C wrapper Foreign function interfaces code. Further we discuss a dynamic linkage framework for binding standard C libraries to FFIs provide the backbone of a language to inter- R across platforms using a universal type infor- face with foreign code. Depending on the design of mation format. The package rdyncall comprises this service, it can largely unburden developers from the framework and an initial repository of cross- writing additional wrapper code. In this section, we platform bindings for standard libraries such as compare the built-in R FFI with that provided by (legacy and modern) OpenGL, the family of SDL rdyncall. We use a simple example that sketches the libraries and Expat. The package enables system- different work flow paths for making an R binding to level programming using the R language; sam- a function from a foreign C library. ple applications are given in the article. We out- line the underlying automation tool-chain that extracts cross-platform bindings from C headers, FFI of base R making the repository extendable and open for Suppose that we wish to invoke the C function sqrt library developers. of the Standard C Math library. The function is de- clared as follows in C: Introduction double sqrt(double x); We present an improved Foreign Function Interface The .C function from the base R FFI offers a call (FFI) for R that significantly reduces the amount of gate to C code with very strict conversion rules, and C wrapper code needed to interface with C. -

Basics of UNIX
Basics of UNIX August 23, 2012 By UNIX, I mean any UNIX-like operating system, including Linux and Mac OS X. On the Mac you can access a UNIX terminal window with the Terminal application (under Applica- tions/Utilities). Most modern scientific computing is done on UNIX-based machines, often by remotely logging in to a UNIX-based server. 1 Connecting to a UNIX machine from {UNIX, Mac, Windows} See the file on bspace on connecting remotely to SCF. In addition, this SCF help page has infor- mation on logging in to remote machines via ssh without having to type your password every time. This can save a lot of time. 2 Getting help from SCF More generally, the department computing FAQs is the place to go for answers to questions about SCF. For questions not answered there, the SCF requests: “please report any problems regarding equipment or system software to the SCF staff by sending mail to ’trouble’ or by reporting the prob- lem directly to room 498/499. For information/questions on the use of application packages (e.g., R, SAS, Matlab), programming languages and libraries send mail to ’consult’. Questions/problems regarding accounts should be sent to ’manager’.” Note that for the purpose of this class, questions about application packages, languages, li- braries, etc. can be directed to me. 1 3 Files and directories 1.
