does anyone have experience with the Pallas Benchmark and the new Myrinet
LanaiXP Cards ?
Problem: I ve got some strang, sporadic gaps on our 32 Node (64 CPU)
processes 32: (32 waiting in barrier)
32x Myrinet Lanai M3F-PCIXD-2 Myrinet-Fiber/PCI-X Interface, 64x 2.4 Ghz,
32 GB Mem
All myrinet cards are running with 133 MHz, (PCI read/write above 800
Compiler: gcc, pgroup, intel
The configuration looks fine. Cards are very fast.
8 byte PingPong below 7usec, Peak Bandwidth near 500 MB/sec
Thanks in advance and have a nice weekend.
