My Responsibilities:

• Development of test exerciser for InfiniBand HCA Adapter. I was involved in the development phase of this test exerciser. Developed exerciser to transfer data among multiple HCA cards through a switching network. Also, between two HCA cards in loop back mode. We needed to test the performance of the system with maximum load. In the process we have found a number of hardware bugs. Implemented all these: QPs, WQEs and CQEs. Also, designed the exerciser in such a way that a single process can have multiple QPs. Worked with Hardware team to identify any hardware fault.
• Skills : C, C , Tnk Test Nano Kernel ,RDMA, IBM POWER Architecture, InfiniBand Architecture , PCI/PCIe, etc.
