This training course provides two 120 minute sessions to enable users to maximize their usage of the Forge tools. We will provide an overview of Linaro Forge, a cross platform, integrated environment for debugging and optimizing parallel codes at any scale. We will provide hands-on demonstrations and exercises of how Linaro Forge reduces development time, simplifies debugging, and eases application performance enhancement on ALC systems.
10:00 - 12:00 Session 1: Ensuring Program Correctness with Linaro DDT
Using sample codes, we will walk through the major capabilities of the debugger to illustrate how DDT can debug applications ranging from a single thread to large scale.
- Submitting a Forge job on your batch system
- Using semantic analysis tools to catch bugs before you even run the code
- How to use sparklines to visualize variable values across processes and threads
- Illustrate memory debugging to trap array out of bounds errors and memory leaks
- Using the array viewer to visualize multi-dimensional variables
- Using watchpoints to halt execution dependent upon expression values
- Offline debugging for large scale debugging, catching non-deterministic errors and continuous integration
- Trace points, a flexible and deterministic printf alternative
- Modifying the definition of your program without re-building using the Evaluate Window
- Debugging Nvidia GPU applications
- Debugging Python applications
13:00 - 15:00 Session 2: Performance Engineering with Linaro Performance Reports and Linaro MAP
We will illustrate how in a matter of minutes you can understand the nature of your application’s performance. We will introduce best practices to attain and maintain optimal performance.
- Understanding the performance road map
- Using Performance Reports to understand your application’s overall performance characteristics
- Characterize file IO behavior
- Isolate workload imbalance issues in codes at any scale
- Measure energy consumption of workloads
- See how the amount of time spent in memory operations varies over time and processes
- Isolate problematic memory access patterns
- Determine how well your application is vectorized
- Profiling Nvidia GPU applications
- Profiling Python applications
