What's New with FMS Version 6.0

• Support for NVIDIA GPU processors. On systems equipped with GPUs, FMS automaticaly detects them and divides the work between the CPUs and GPUs. GPUs can provide an order of magnitude or more in performance, cost/performance and power reduction. Several FMS Parameters have been added to control the options available with GPUs.

• The IWATCH Performance Report has been added to provide a WEB based report as FMS jobs are running. The information includes current details on the CPUs, GPUs, Memory, Disks, Files, Software, Subroutine calls and System usage. In addition Performance data showing the progress of the calcualtion and rate of performing useful work (matrix terms filled, flops, etc.) is also included.

• Subroutines FMSPSH and FMSPOP have been added to allow you to instrument your subroutines. By placing a call to FMSPSH and the beginning of the routine and FMSPOP at the end, FMS will compute the amount of time spent in that routine. In additon your subroutine will be available for monitoring using the IWATCH performance report.

• Subroutines FMSILG, FMSRLG, FMSCLG have been added to allocate memory that is local to a processor. Using local memory can improve performance on machines with several processors, especially NUMA machines. When the memory is no longer required, subroutines FMSILR, FMSRLR, FMSCLR can be called to return it.

• The license file is now named fmslic.txt. License files named fmslic.52 will not work with version 6.0.

New FMS Subroutines

• FMSPSH
  Add your subroutine to the FMS call stack.

• FMSPOP
  Remove your subroutine from the FMS call stack.

• FMSILG, FMSRLG, FMSCLG
  Allocate integer, real or complex memory local to each processor.

• FMSILR, FMSRLR, FMSCLR
  Return the integer, real or complex local memory that was allocated.

New FMS Parameters

• MAXGPU
  Determines the number of GPUs to use.

• GPUFL
  Controls the use of GPUs.

• GPUPR
  Determines how much information is printed about the GPUs.

• ICHUNK
  Controls how data is distributed among the GPUs.

• IMMPCT
  Specifies the percentage of work done by the CPUs during matrix multiply computations.

• ITRPCT
  Specifies the percentage of work done by the CPUs during trinagle solve computations.

• MAXEVT
  Read only. Returns the maximum number of events that were recorded during a single call to a GPU routine.

• CUPATH
  Path to the nvidia-smi program.

• IOLAST
  Physically reserve file space when a file is opened by writing to the end of the file.
  NOTE: On version 5.2 the default was to write to the end of the file. On version 6.0 the default is NOT to write to the end of the file since this can take a considerable amount of time for large files. Setting this Parameter to 1 will cause the same behavior as version 5.2.

New Example Problems

• EXAMPLE_21
  This example illustrates the use of the matrix multiply routine FMSMM

• EXAMPLE_22
  This example is used to measure disk performance.

• EXAMPLE_23
  This example shows how OpenMP and FMS calls can be mixed.
