MPI_Init issue

When you get an error like the following this means that MPI_Init is expecting argc/argv. NULL values being passed there are not sufficient. Passing NULL to MPI_Init works on the cluster at ASC though - that is, the program that gives the following error on Olympus runs perfectly on the cluster at ASC.

Ant Script Problems

When stuck, check:

1) the version of the jar files that are being used. Make sure they are from a stable build. For example, ant-contrib-1.0b has bugs in it.


2) check the classpath. For example, { classname="FileCopy" } is correct but {
classname="C:/AMMA/Eclipse3.3/FileCopy/bin/FileCopy"} is not.
