Intel tunes Saudi Fortran

Intel has been working with Saudi Aramco to tune Fortran code running on its 1,800 cluster seismic computer.

Intel Solution Services (ISS) have been helping Saudi Aramco’s geophysical programmers optimize their pre-stack time migration code. This runs on an 1,800 processor cluster located in Dhahran. During two days of ‘intensive programming’, Intel Solution Services optimized the PSTM code using the Intel Fortran for Linux 6.0 compiler and the Intel VTune Performance Analyzer to identify parts of the code for further optimization.


ISS’ Gernot Hoyler said, “We got the PSTM application to run 33 percent faster on the same Intel Chip. With additional tuning, we hope to boost performance by 50 percent.” Saudi Aramco’s PSTM application runs on a cluster of 900 IBM rack mounted nodes, each with 2GB of memory and twin, 1.4 GHz Pentium III processors. The operating system is RedHat Linux 7.2 and the cluster interconnect is 100Mb Fast Ethernet. The system, which started out with 128 processors is to grow to 4,000 by the end of 2002.
