Now you can step through each process independently using the two debugger windows. Navigate to Configuration Properties:: The first prompt will be rank 0 in a job mxnual size 2.

This is an advantage over the cygwin environment because in order to get your cygwin DeinoMPI application to run you have to copy the cygwin1. Debugging Applications Debugging parallel applications is hard but there are a few options provided by DeinoMPI that can help. When you click the Show Messages button the last N calls will be printed out for each process.
They need to be copied to all the nodes that will participate in the MPI job or they need to be copied to the same location as the MPI application. One set is all uppercase symbols and the other is all lowercase with one trailing underscore.

With the import library created icpi could be compiled with the following command:. There was a mistake in the readme in that the configuration files need to be place in the bin directory and not the root directory.
This document explains how to compile and debug applications for DeinoMPI with examples from devv compilers. Here is a batch file that can be run to set the variables for each process: The Portland Group compiler uses de lower case format.
Create a project and add your source files. Otherwise you can add code to the beginning of your application to cause it dsv wait.
Change to the DeinoMPI directory and execute the following command:. All capital external names and all lower case external names with a trailing underscore. The slink tool creates an import library directly from the Fortran dll from the DeinoMPI distribution.
Bring up the properties dialog for your project by right clicking the project name and selecting Properties. Bring up the settings for the project by hitting Alt F7. You could also make this Sleep block depend on a command line parameter so that you can attach to a specific process instead of all of the dfv. The following libraries contain the specified formats:.
The Pelles C compiler can be found in various places, http: The devv boxes are identical for setting the include and library paths. A sample MPI application was compiled by adding the following settings: There are at least two ways you can use a debugger to step through your parallel processes. From within the MSYS shell the example cpi application was eev and run using mpiexec: Change the rev to use the thread safe libraries Compile your application.
For Fortran applications it is located under the fortran:: It is important to do so because the output of applications is buffered by default and must be flushed if you want to see the output immediately. Then the icpi sample application was created from a command prompt.
The primary goal of Jumpshot is 22.214.171.124 view the runtime patterns of an MPI application and then analyze these patterns to see if changes can be made to the code to optimize the application. See the Jumpshot manual for information. Change to the DeinoMPI directory and execute the following command: These methods have been tested using the Visual Studio debugger but may also work with other debuggers.
At this point you will have two debuggers open. First an FTN95 command prompt was brought up from the Start menu link installed with the package.
Creating the import library took two steps:. The Intel compiler can be integrated into Developer Studio. Then you will be able to step through the process.
Debugging parallel applications is hard but there are a few options provided by DeinoMPI that can help. Then you can compile the example cpi application from a command prompt with this command:.
This compiler drv worked. Depending on the user privileges you may get Access Denied errors when trying to attach to processes started by mpiexec. Watcom The C compiler from OpenWatcom was tested.
