At the time of writing this paper, our attempts to 'port' mpiJava to Linux are in progress. We are currently experiencing problems similar to those encountered during our early attempts to create the interface on Solaris, mentioned in section 3.1 . Sun's releases the JDK for Solaris and NT platforms first. On other platforms, such as Linux, it is necessary for developers to 'port' the JDK. The most recent release of the JDK for Linux is 1.1.7 and this is version is known to be the cause of our problems. It is anticipated that JDK 1.2 will be available for Linux shortly and that we will be able to report our experiences with Linux at the IPPS/SPDP 99 workshop in April 1999.
