Description

This tool is designed to benchmark data transfers between two depot collections. The two depot collections don’t have to be the same size.

Options

-d

Enable minimal debug output

-dd

Enable FULL debug output

-network_chksum type blocksize

Enable network checksumming for transfers. type should be SHA256, SHA512, SHA1, or MD5. blocksize determines how many bytes to send between checksums in kbytes.

-disk_chksum type blocksize

Use block level checksum allocations. type should be NONE, SHA256, SHA512, SHA1, or MD5. If NONE is specified it will force the creation of allocations without checksums. If the option is not specified then the resources default options are used. blocksize determines how many bytes to send between checksums in kbytes.

-validate

Validate disk chksum data. Option is ignored unless disk chksumming is enabled.

-config ibp.cfg

Use the IBP configuration defined in given file. nthreads overrides value in config file unless -1.

-phoebus ppath

Use Phoebus protocol for data transfers. The Phoebus path si a comma separated List of phoebus hosts/ports, eg. gateway1/1234,gateway2/4321.

-tcpsize tcpbufsize

Use this value, in KB, for the TCP send/recv buffer sizes.

-duration duration

Allocation duration in sec. Needs to be big enough to last the entire run. The default duration is 900 sec.

-sync

Use the synchronous protocol. Default uses asynchrounous transfers.

-alias

Use alias allocations for all I/O operations.

-progress

Print completion progress.

-alias-source

Use alias allocations for source allocations

-alias-dest

Use alias allocations for the destination allocations

src_n_depots

Number of source depot tuplets

dest_n_depots

Number of destination depot tuplets

depot port RID

Depot tuple comprised of the depot hostname, port and resource to use. A RID of 0 lets the depot pick a resource.

nthreads

Max Number of simultaneous threads to use. Use -1 for defaults or value in ibp.cfg

ibp_timeout

Timeout(sec) for each IBP copmmand

count

Total Number of allocations on destination depots

size

Size of each allocation in KB on destination depot
