CALL FOR PAPERS Special Issue of The International Journal of Supercomputer Applications and High Performance Computing on I/O in Parallel Applications Parallel computers are increasingly being used for applications with significant I/O requirements. In many such applications, I/O is the main factor limiting performance and scalability. The International Journal of Supercomputer Applications and High Performance Computing will be publishing a special issue on I/O in Parallel Applications. Papers are solicited that describe the nature of I/O in real I/O-intensive parallel applications, methods and tools used for I/O, performance obtained, problems experienced, etc. Of particular interest are experiences with applications that highlight the strengths and weaknesses of existing hardware and software support and user interfaces for parallel I/O. All submitted papers will be refereed. The papers must be unpublished and not under consideration for publication elsewhere. All papers must be submitted electronically by sending the PostScript file by e-mail to thakur@mcs.anl.gov. The deadline for submitting papers is May 10, 1997. Authors will be notified of the publication decision by July 25, 1997.
