There is a big problem in concurrent use of the parallel storage systems on HPC Clusters. This might spoil the performance improvement that might otherwise be obtained by optimizations of MPI-IO, such as data sieving, two-phase collective I/O and etc.
Our approach to achieve performance guarantees is to allow users / applications to explicitly reserve I/O throughput of the storage system in advance, with start and end time of the access.

Modern seismologists are presented with increasing amounts of data that may help them better understand the Earth’s structure and systems. However:
- they have to access these data from globally distributed sites via different transfer protocols and security mechanisms;
- to analyse these data they need to access remote powerful computing facilities;
- their experiments result in yet more data that need to be shared with scientific communities around the world.

The turbulent global digital-data revolution is delivering a bonanza of research opportunities. In most disciplines these promise significant advances in understanding, but today we have to invest unsustainable amounts of intellectual effort and energy to obtain those advances because our conceptual tools and their supporting technology have not yet grown to meet the challenge of data wealth. The talk reviews some of the ways in which we can sharpen our data-intensive tools and discuss early experiences in several application areas.
