Thanks Wesley. Actually Windows is a constraint that plays a major role in deciding the software I can use. The next time basictests runs, the new process manager and device pair will be added to the tests, and the web page will reflect the new tests.

The first of these is the entire output file. The second contains only the output of make that was might contain warnings or errors about the make.

The remaining eight files contain the test results and the failure-only results the files with the -fail extension. If more details are required, you will need to check the directory in which the tests were run.

The -help option to specialtest describes the options that can be used to run a subset of tests or to select different combinations of process managers or devices. For example, to run the tests on your own copy of MPICH2 and place the results in a private location, use. The configure tests are run with the script testoptions. To run the coding checks, change to a directory that contains MPICH2 and execute the following command:. This assumes that you are running on one of the MCS division Linux systems; you can install the buildsys tools and using codingcheck from your own installation if you need to run the coding check on a different system.

The report of problems detected is sent to standard output. The above command will produce a relatively comprehensive report. An explanation of some of the rules that are applied by the style checker are in the Coding Standards. Currently, the coding checker produces a unified report about all problems. To find specific problems, you can use grep or view the report it is a text file in your favorite editor. Some simple examples are:. These are uses that are viewed as erroneous. Each file should have a style header to avoid unnecessary reformatting when the file is edited e.

There are a number of functions, such as strcat , that should never appear in good code because of the potential for memory overwrites even if the code is surrounded by length checks, any reader of the code must take the time to ensure that those checks are correct; it is better to avoid them. Other routines, such as malloc , interfere with debugging tools that are built into the code. Yet other functions, such as setvbuf or snprintf , are either not portable to all operating systems or are only part of C99 or later, and may pose portability problems for users with older e.

The program itself is a simple perl script; if you wish to change the tests for yourself, make a copy and update the values of the following variables, found near the top of the file:.

Location of program that is used to check for global symbols, along with any command-line arguments. There are several easy ways to get a quick look at the global symbols. The easiest is to use the nm program on libmpich. However, you will need to filter the output to find any non-conforming names. If not, you may have issues with missing dependencies. For any issue, I highly recommend copying and pasting the error message directly into Google. If you already have the hardware and resources to setup a local cluster, I suggest you proceed to the tutorial about running an MPI cluster in LAN.

If you have built a cluster in either way or simply want to run the rest of the lessons from your machine, proceed to the MPI hello world lesson , which provides an overview of the basics of programming and running your first MPI program.
