Manufacturer/Processor Type, Speed, Count, Threads, Processes
Includes the manufacturer/processor type, processor speed, number of processors, threads, and number of processes.
Move mouse over this column for each row to display additional information, including; manufacturer, system name, interconnect, MPI, affiliation, and submission date.

Run Type

Run Type, indicates whether the benchmark was a base run or was optimized.

Randomly Ordered Ring Latency ( per process )
Randomly-Ordered Ring Latency, reports latency in the ring communication pattern. The communicating processes are ordered randomly in the ring. The result is averaged over various random assignments of processes in the ring.
Unit: micro-seconds
Naturally Ordered Ring Latency ( per process )
Naturally Ordered Ring Latency.
Unit: micro-seconds
Ping-Pong Latency
Ping-Pong Latency, reports the latency for a number of non-simultaneous ping-pong tests. The ping-pongs are performed between as many as possible (there is an upper bound on the time it takes to complete this test) distinct pairs of processors. The test uses MPI standard send and receive routines. Unit: micro-seconds
Maximum Ping-Pong Latency
Maximum Ping-Pong Latency, reports the maximum latency for a number of non-simultaneous ping-pong tests. The ping-pongs are performed between as many as possible (there is an upper bound on the time it takes to complete this test) distinct pairs of processors. The test uses MPI standard send and receive routines. Unit: micro-seconds
Minimum Ping-Pong Latency
Minimum Ping-Pong Latency, reports the minimum latency for a number of non-simultaneous ping-pong tests. The ping-pongs are performed between as many as possible (there is an upper bound on the time it takes to complete this test) distinct pairs of processors. The test uses MPI standard send and receive routines. Unit: micro-seconds
Average Ping-Pong Latency
Average Ping-Pong Latency, reports the average latency for a number of non-simultaneous ping-pong tests. The ping-pongs are performed between as many as possible (there is an upper bound on the time it takes to complete this test) distinct pairs of processors. The test uses MPI standard send and receive routines. Unit: micro-seconds
Ping-Pong Bandwidth
Ping-Pong Bandwidth, reports the bandwidth for a number of non-simultaneous ping-pong tests. The ping-pongs are performed between as many as possible (there is an upper bound on the time it takes to complete this test) distinct pairs of processors. The test uses MPI standard send and receive routines. Unit: Giga Bytes per second
Maximum Ping-Pong Bandwidth
Maximum Ping-Pong Bandwidth, reports the maximum bandwidth for a number of non-simultaneous ping-pong tests. The ping-pongs are performed between as many as possible (there is an upper bound on the time it takes to complete this test) distinct pairs of processors. The test uses MPI standard send and receive routines. Unit: Giga Bytes per second
Minimum Ping-Pong Bandwidth
Minimum Ping-Pong Bandwidth, reports the minimum bandwidth for a number of non-simultaneous ping-pong tests. The ping-pongs are performed between as many as possible (there is an upper bound on the time it takes to complete this test) distinct pairs of processors. The test uses MPI standard send and receive routines. Unit: Giga Bytes per second

Average Ping-Pong Bandwidth, reports the average bandwidth for a number of non-simultaneous ping-pong tests. The ping-pongs are performed between as many as possible (there is an upper bound on the time it takes to complete this test) distinct pairs of processors. The test uses MPI standard send and receive routines. Unit: Giga Bytes per second
Randomly Ordered Ring Bandwidth ( per process )
Randomly Ordered Ring Bandwidth, reports bandwidth achieved in the ring communication pattern. The communicating processes are ordered randomly in the ring. The result is averaged over various random assignments of processes in the ring.
Unit: Giga Bytes per second per process
Naturally Ordered Ring Bandwidth ( per process )
Naturally Ordered Ring Bandwidth, reports bandwidth achieved in the ring communication pattern. The ring is formed with consecutive processes in MPI_COMM_WORLD.
Unit: Giga Bytes per second per process
