- Characterizing Parallel File-Access Patterns on a Large-Scale
Multiprocessor by Apratim Purakayastha, Carla Schlatter Ellis,
David Kotz, Nils Nieuwejaar and Michael Best.
ABSTRACT:
Rapid increases in the computational speeds of multiprocessors have
not been matched by corresponding performance enhancements in the
I/O subsystem. To satisfy the large and growing I/O requirements of
some parallel scientific applications, we need parallel file
systems that can provide high-bandwidth and high-volume data
transfer between the I/O subsystem and thousands of
processors. Design of such high-performance parallel file systems
depends on a thorough grasp of the expected workload. So far there
have been no comprehensive usage studies of multiprocessor file
systems. Our CHARISMA project intends to fill this void. The first
results from our study involve an iPSC/860 at NASA Ames. This paper
presents results from a different platform, the CM-5 at the
National Center for Supercomputing Applications. The CHARISMA
studies are unique because we collect information about every
individual read and write request and about the entire mix of
applications running on the machines. The results of our trace
analysis lead to recommendations for parallel file system
design. First, the file system should support efficient concurrent
access to many files, and I/O requests from many jobs under varying
load condit ions. Second, it must efficiently manage large files
kept open for long periods. Third, it should expect to see small
requests, predominantly sequential access patterns,
application-wide synchronous access, no concurrent file-sharing
between jobs, appreciable byte and block sharing between processes
within jobs, and strong interprocess locality. Finally, the trace
data suggest that node-level write caches and collective I/O
request interfaces may be useful in certain environments.

ABSTRACT:
We have been developing high-level checkpoint and restart methods
for Dome (DIstributed Object Migration Environment), a C++ library
of data-parallel objects that are automatically distributed using
PVM. There are levels of programming abstraction at which fault
tolerance mechanisms can be designed; high-level, where the
checkpont and restart are built into our C++ objects, but the
program structure is severly constrained; high-level with
preprocessing, where a preprocessor inserts extra C++ statements
into the code to facilitate checkpoint and restart; and low-level
where periodically an interrupt causes a memory image to be written
out. Because we consider portability (both of our libraries and
the checkpoints they produce) to be an important goal, we focus on
the higher-level checkpointing methods. In addition, we described
an implementation of high-level checkpointing, demonstrate it on
multiple architecutres, and show that it is efficient enough to
provide good expected run times with low overhead, even in the case
of frequent faiulres.

ABSTRACT
New file systems are critical to obtain good I/O performance on
large multiprocessors. Several researchers have suggested the use
of collective file-system operations, in which all processes in an
application cooperate in each I/O request. Others have suggested
that the traditional low-level interface read, write, seek) be
augmented with various higher-level requests (e.g., read matrix),
allowing the programmer to express a complex transfer in a single
(perhaps collective) request. Collective, high-level requests
permit techniques like two-phase I/O and disk-directed I/O to
significantly improve performance over traditional file systems and
interfaces. Neither of these techniques have been tested on
anything other than simple benchmarks that read or write
matrices. Many applications, however, intersperse computation and
I/O to work with data sets that cannot fit in main memory. In this
paper, we present the results of experiments with an

ABSTRACT
This paper summarizes and organizes the views expressed and the
issues discussed by a broad cross section of the participants
at the workshop on Parallel Object-Oriented Methods and
Applications (POOMA) held in Santa Fe, New Mexico between Dec
5-7, 1994 [11]. About 6 years after the first C++ conference,
object-oriented programming (OOP) and its relevance to
large-scale applications was discussed at this workshop. The
special focus was on the effectiveness of OOP methodology in
terms of performance when coupled with the parallel programming
paradigm.

University, USA.
ABSTRACT:
The Tremendous storage space required for a useful data base of
traces has driven a search for trace compaction techniques. In
this paper we present an information-lossless trace compression
scheme that can reduce both storage space and access time by an
order of magniture or more, compared to ASCII-format traces,
without discarding either references to or inter-reference timeing
from the original trace.
This techniqute has been selected as the standard trace format for
an extensive new trace base that will be made accessible to the
international research and teaching community.
