Gfarm file system is a network shared file system that supports scalable I/O performance in distributed environment. It can federate local disks of network-connected PCs and compute nodes in several clusters.

PiP is a user-level library to have the best of the both worlds of multi-process and multi-thread parallel execution models. PiP allows a process to create sub-processes into the same virtual address space where the parent process runs. The parent process and sub-processes share the same address ... [More] space, however, each process has its own variable set. So, each process runs independently from the other process. If some or all processes agree, then data own by a process can be accessed by the other processes. Those processes share the same address space, just like pthreads, and each process has its own variables like a process. The parent process is called PiP process and a sub-process are called a PiP task. [Less]
