PARAM
PARAM – PARAllel Machine
Developed by Center for Development of Advanced Computing (C-DAC) India
PARAM Padma is the latest in the line of PARAM series after PARAM 8000, PARAM 9000 and PARAM 10000
Introduced in 2003
Its a next generation high performance scalable computing cluster
PARAM Padma's theoretical peak performance of complete configuration is 1.13 TFlops
PARAM Machine Architecture
Cluster Personality
- Data Link Provider Interface (DLPI) driver allows mapping of common network protocols to the underlying network
MPP (Massively Parallel Processor) Personality
- Architecture allows microkernel to be loaded on compute nodes
- implements custom designed Concurrent Runtime Environment (CORE)
- Standard message passing interface
1. Parallel Virtual Machine (PVM)
2. Message Passing Interface (MPI)
PARAS Microkernel Architecture
Message for high MPP
Supports multiple tasks with a paged virtual memory space
Multiple threads of execution within each task
Message based interprocess communication
Communication between tasks by message passing
Location independent interprocess communication supported by port abstraction
Microkernel Architecture
PARAS service request dispatcher routes all requests to appropriate service provides
Resource Managers
- Process Manager
- Virtual Memory Manager
- Inter-Process Communication (IPC) Manager
PARAMNet II - NIC
Provides interface to SANSW8 (8 port ) and SANSW16 (16 port) PARAMNet II switch
Supports for connection oriented and connectionless protocols
Can be configured for other protocols
Capable of performing I/O from paged virtual memory
